Describe the difference(s) between local and global winds.
Explanation:
The term global winds refers to the six major wind belts that encircle the globe.
Local winds, however, are the winds, or breezes, that are stirred up by the temperatures and topographical features of a small region or area. This is especially true of coastal areas.
Thinking about taxonomy, the basic unit of naming, that includes
members with the ability to reproduce with each other, is?
Answer:
species.
Explanation:
Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals. Thus, it is the biological classification of living organisms based on similarities or characteristics such as eyes, number of legs, etc.,
The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; kingdom, domain, phylum, family, order, class, genus and species.
In taxonomy, species refers to the basic unit of naming that includes members such as mammals and reptiles with the ability to reproduce with each other to birth new offsprings and exchange genetic informations. Some examples of species include Homosapiens, Vulpes, Elephas maximus, Pinus banksiana, Alces laces, Ursus americans, Canis lupus, etc.
In conclusion, taxonomy helps scientist to have good understanding and knowledge when studying various organisms.
The theory of endosymbiosis is based on Multiple Choice similarities between chloroplasts and other organelles in animals. evidence from the fossil record. the knowledge that ribosomes are structures found in bacteria, plants, and animals. the experiments in which bacteria were made to grow in plant cells forming chloroplasts. the observations that chloroplasts and mitochondria resemble bacteria.
Answer:
the observations that chloroplasts and mitochondria resemble bacteria
Explanation:
The Endosymbiotic Theory is a theory that enables us to understand the origin of eukaryotic cells. The Endosymbiotic Theory posits that the mitochondria and chloroplast, which are organelles found in the eukaryotic cells, were once prokaryotic microbes that were first ingested by amoeba-like organisms and subsequently evolved by developing a symbiotic relationship with them. Some of the most important lines of evidence that supports this theory are: 1-chloroplasts and mitochondria resemble prokaryotic cells, i.e., they have a similar size, replicate by binary fission and there are unicellular eukaryotic protists that have filamentous temperature-sensitive proteins at their division plane (similarly to bacteria), and 2- chloroplasts and mitochondria are organelles with their own DNA and their own ribosomes (which are similar to those of bacteria).
Answer:
the observations that chloroplasts and mitochondria resemble bacteria
Explanation:
Replication. Mitochondria and chloroplasts make more of themselves in much the same way as bacteria reproduce. ... Like bacteria, mitochondria and chloroplasts grow in size, duplicate their DNA and other structures, and then divide into two identical organelles.

Homeostasis is maintained through feedback mechanisms.
a. True
b. False
Answer:
a. True
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Homeostasis is maintained through feedback mechanisms, which are either positive or negative feedback.
During a negative feedback, a sensor and a control center in the body of a living organism maintains blood glucose to regulate blood pressure by releasing glucagon to increase blood sugar or releasing insulin to decrease blood sugar.
For a positive feedback, a sensor and a control center aids child birth by causing the uterine to contract.

Australia and New Zealand have a wide array of plants and animals found nowhere else because those organisms evolved in _____. Question 9 options: in the Southern Hemisphere
Answer:
These organisms evolved inside these countries.
Explanation:
Organisms evolved inside Australia and New Zealand countries because these two countries are isolated means there is no way for the movement of crops or animals from other regions into these environment. There is a big ocean present between these countries and other countries so the organisms only evolved inside these two countries not from the outside environment.
What term is used to describe the number of chromosomes in a gamete, such as
an egg cell or a sperm cell?
Answer:
The biology term, haploid can also refer to the number of chromosomes in egg or sperm cells, which are also called gametes
The term used to describe the number of chromosomes in a gamete would be haploid.
Gametes are usually formed by meiosis and meiosis is referred to as reductional division. When a normal diploid (2n) cell divides by meiosis, the daughter cells would have half the number of chromosomes of the parent cell. In other words, the daughter cells will have n number of chromosomes as opposed to 2n.
Cells with n chromosome numbers are generally referred to as haploid while those with normal 2n chromosome numbers are said to be diploid. Egg and sperm cells are haploid cells.
More on haploid cells can be found here: https://brainly.com/question/15475325
A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are exposed exclusively on one side of the membrane or both binding sites are exposed exclusively on the other side of the membrane. The protein can switch between the two conformational states only if both binding sites are occupied or if both binding sites are empty, but cannot switch if only one binding site is occupied. What kind of protein do these properties define
Answer:
The protein is a symport protein.
Explanation:
Transport proteins are proteins which are involved in the transport of solutes across the cell membrane. The binding of the solute to be transported across the membrane causes a conformational change in the shape of the protein, thereby moving the molecule to the side of nthe membrane it is to be transported. The difference in the concentration of the solute across the membrane known as concentration gradient is mainly responsible for the transport of molecules by the transport proteins.
There are three types of transport proteins: uniport, symport and antiport transport proteins.
Uniporters are involved in moving only one molecule across a membrane
Symporters are involved in moving two or more molecule across a membrane in the same direction.
Antiporters are involved in moving two or more molecule across a membrane in opposite directions.
From the description of the transport protein in the question, both solutes A and B are moved across the membrane simultaneously in the same direction. Therefore, the protein is a symport protein.
Which type of reproduction provides organisms with the following advantages? Desirable traits can be selectively bred for in a population of organisms. More genetic diversity that might benefit individuals when environment changes.
A. Asexual reproduction
B. Sexual reproduction
Answer:
Sexual Reproduction
Explanation:
Since sexual reproduction automatically causes genetic diversity(crossing over, DNA from both parents, etc.) it produces desirable traits for organisms. Asexual reproduction does not bring in new and desirable traits and is more of a copy of the parent.
Receptor binding motifs such as RGD have highly selective recognition for cell adhesion. Outline a strategy for incorporating a cell adhesive recognition domain to a biomaterial. Address the problems surrounding domain quantity, type, and affinity in your discussion.
Answer:
Explanation:
RGD stands for Arginine Glycine Aspartate and is a three-amino-acid peptide. It is the most extensively utilized adhesive peptide for adhering diverse cell types to a variety of biomaterials. Integrins, fibrinogen, osteopontin, fibronectin, and bone sialoprotein, as well as collagens and laminins, all include an RGD primary binding domain. As a result, the synthetic (artificial) peptide RGD may bind to a wide range of integrin types. The artificial RGD retains its functioning through the sterilizing and processing processes of biomaterial creation because of its recognition advantage. This feature denotes the immune reactivity and pathogen transmission during xenograft.
Affinity can be modulated by the conformation of artificial RGD. The efficacy of RGD is also determined by the in vitro deposition of cells on the surface of the material sample.
The molecular processes unravel its effectiveness throughout its use as a scaffold foundation in in-vivo models. The fact that artificial RGD cannot work well in isolation is now a major aspect that defines its activity.
It has been discovered that cells release a variety of integrin-binding proteins that are more effective in activating integrin signalling than pure RGD. As a result, most biomaterials will bind and adsorb these proteins rather than RGD. As a result, a serum-free medium is employed in the majority of in vitro research.
As a result, biomaterials are supplied with RGD as well as quasi polymers such as polyethylene glycol to reduce the variance produced by native proteins. The addition of additional amino acids to RGD based on natural sequences can increase its biological activity, which can aid in the development of new tissues and the stimulation of cellular responses and signalling.
The amino terminal endpoint of the peptide, as well as the carboxyl group of the material surface, establish a covalent connection, which binds the peptide to just the surface of its biomaterial. Cell adhesion biomaterials are made from a variety of cell adhesion materials, including poly-L-lysine, mussels adhesive protein (MAP), and outer membrane (extracellular matrix) proteins.
Because MAPS are high in Dihydroxyphenylalanine and lysine, RGD is coupled with either of these to boost its cell adhesion capability. As a result, they can also aid in the attachment to damp or moist surfaces. It may also firmly adhere to glass, metals, and plastics. The addition of thiol groups to a peptide can also aid in its orientation and boost its stability.
The gap and density of this peptide sequence and structure on the biomaterial surface may be adjusted using a micro and nanotechnology (nanoscale patterning) method, which also improves ligand binding accuracy. Cellular reactions and cell activity are also under its control. Integrin receptors have been shown to be between 9 - 12 nm in size, therefore nanoscale surface patterning is crucial.
As a result, the above methods serve as a strategy for incorporating a cell adhesion recognition domain into a biomaterial while taking into account all of the technical intervention affecting its quantity, type, and affinity to the top layer for cell adhesion as a functioning tissue rather than a monolayer.

Diminished bone mineral density can result from inactivity. In contrast _______________ can stop if not reverse the loss of bone mineral density.
Answer: Resistance exercise
Explanation:
A decrease in the quantity of mineral in the bone can occur due to inactivity or less body movements which may be as a result of old age or a disease condition.
RESISTANCE EXERCISE is a type of training in which the muscles are subjected to work against a weight to help increase the strength of the muscles. Below are the different forms of resistance exercise:
--> Resistance bands: these bands provides resistance when they are stretched.
--> Suspension equipment: this training tool uses the body weight and gravity to form resistance.
--> Your own body weight: one can conveniently use the body weight for push ups and squats.
Generally, the resistance exercise helps to reverse the loss of bone mineral density through increasing muscle strength and tone and reducing inactivity in the muscles that led to diminished bone mineral density.

Fire and Mello conducted an experiment where they added no gene X RNA (b), anti-sense gene X RNA (c) or double stranded gene X RNA (d) to C. elegans embryos. They then did a hybridization experiment examining gene X mRNA levels in the embryo. Square (a) is a no probe control. How does this act as a control
Answer:
The correct answer is - It shows that an RNA probe is necessary to get a signal.
Explanation:
A probe is a specific single-stranded sequence of DNA or RNA that recognizes its complementary sequence in a particular sample genome for synthesis. The RNA probe is placed into close contact with the given sample under a specific environment that allows the RNA probe sequence to hybridize with its complementary sequence.
In this case, square a is the condition where no RNA probe is persent whereas all three other conditions have some sort of RNA probe, however, in C there is no Gene X probe but their probe present. To get a signal in hybridization RNA probe is required and that can be used as control as it can be used to compare if a signal is received or not.

Explain why insertions and deletions are called frameshift mutations, usingthe terms reading frame, codons, and amino acids in your answer.
Answer: A reading frame shift mutation involves the insertion or deletion of a certain number of nucleotides that is not divisible by three, because the cell reads a gene in groups of three bases (a codon). This type of mutation can change the reading frame causing a different translation from the original, because it will code for different amino acids.
Explanation:
DNA is the double-stranded molecule composed of nucleotides which are the functional unit of nucleic acids and are composed of a base (which can be Adenine, Thymine, Guanine, Cytosine, and Uracil replacing Thymine in RNA), a phosphate group and a sugar which can be ribose in RNA and deoxyribose in DNA. The reading frame is one of the possible ways in which a sequence of DNA or RNA nucleotides can be divided to form a group of codons that are consecutive and non-overlapping. A codon consists of a set of three nucleotides and each codon codes for an amino acid during translation or protein synthesis. When DNA is transcribed into messenger RNA (mRNA), this mRNA is read on ribosomes during translation and the three bases of each codon will code for an amino acid.
A single-stranded nucleic acid (RNA) molecule has a phosphate end, called the 5' end (read five prime end) and a hydroxyl end, called the 3' end. These ends define the 5'-3' direction. There are three possible reading frames in which a nucleotide sequence can be read in the 5'-3' direction. Each of these reading frames could start at a different nucleotide of the same codon. In a double-stranded nucleic acid (DNA), there are also three additional reading frames corresponding to the complementary strand, but in an antiparallel direction. Since the two strands of a double-stranded nucleic acid are antiparallel, the 5'-3' direction of the second strand corresponds to the 3'-5' direction of the first strand.
Generally, there is at most, a single biologically relevant reading frame for a given section of a nucleic acid, and that reading begins when a start codon indicating the initiation of protein synthesis is found in the messenger RNA. And the process stops when a stop codon is reached.
An insertion is a type of mutation that involves the addition of genetic material. It can be small and involve a single DNA base pair, or large and involve a fragment of a chromosome. A deletion is a type of genetic mutation in which genetic material is lost, from a single DNA nucleotide pair to an entire chromosome fragment. A reading frame shift mutation involves the insertion or deletion of a certain number of nucleotides that is not divisible by three, because the cell reads a gene in groups of three bases, as it was explained before. This type of mutation can change the reading frame causing a different translation from the original.
