Explanation:
The diagram shows a model of a section of double-stranded DNA. The straight lines and dotted lines represent chemical bonds between the
components of the molecule.
During DNA replication, which chemical bonds break apart? Select all that apply.
The DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.
What role does DNA replication play?DNA replication is the process of making two DNAs from a single DNA, and here the hydrogen bonds that are present between the bases, such as thymine and adenine, which have two hydrogen bonds, and guanine and cytosine, which have three hydrogen bonds, break. The purpose of DNA replication is to make a copy of the genetic content of the cell so that it can be passed to other cells.
Hence, the DNA has two double strands, and they have different chemical bonds, so during the DNA replication, the hydrogen bonds that are present between the two strands break to separate the DNA.

Which MOLECULES are DIRECTLY involved in protein synthesis-translation? (choose 3)
1. mRNA
2. rRNA
3. tRNA
4. cytoplasm
5. sugar
6. DNA
7. Golgi Apparatus
8. amino acid
The translation is directly facilitated by mRNA, tRNA, and rRNA. A specific DNA sequence termed a gene is used as a template during gene transcription to produce a messenger RNA (mRNA), so 1, 2, and 3 are directly involved.
What is the process of protein synthesis?The ribosomes are the next location this mRNA visits before being employed to translate it into a protein.
A ribonucleoprotein complex called the ribosome is made up of proteins and ribosomal RNA (rRNA) sequences.
The linear order of the amino acids that will be added to the protein is indicated by the triplets of nucleotides, or "codons," in the mRNA.
Therefore, the process of translating mRNA into the chain of amino acids that makes up the produced protein occurs in ribosomes in the cytoplasm of the cell.

While looking at a cell under a microscope you notice there is no nucleus and the
chromosomes are double stranded (they have 2 sister chromatids). What phase of mitosis is
the cell probably in?
Answer:
This is the Prophase. Mitotic Prophase,
Explanation:
The process cell division where the cells divides two similar daughter cells(2n) is called mitosis. Therefore it is called a multiplication division because two daughter cells are form from a single the mother cells. Each of the daughter cells can also undergo Futher divisions.
It is the second stage fist mitotic cells division after the first phase called Interphase.
In this stage, the nuclear membrane disappear, nucleolus disintegrate and the nucleus disappeared This is followed by the constriction of the chromosome to sister chromatids.
The constricted nuclear membrane leads to the releases of the chromatids This is followed by the formation of the spindles fibers which are needed for the movement of chromosome for cross over.
other phases are Interphase Prophase Metaphase Anaphase Telephase(IPMAT)

Why do we use models in our everyday lives especially for the weather?
P.S- need the answer ASAP!! please helpppp
Answer:
In order to predict weather.
Explanation:
We use models in our everyday lives especially for the weather in order to gain information about the weather of next few days. This model is very necessary because it predicts the weather which is very important for the farmers. Observations of pressure, wind, temperature and moisture are obtained from different instruments such as ground sensors and weather satellites. The observations or data are put into the models which gives information about the weather.
Tropical rain forests receive heavy rainfall. How do the trees and plants of this region withstand rotting?
Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.
How do animal behaviors lead to successful reproduction and growth of their young?

Answer:
The correct answer would be - Archaea or bacteria.
Explanation:
All prokaryotic organism either archaea or bacteria both are unicellular organism that contain cytoplasm, genetic materia (DNA), ribosomes, plasma membrane, cell wall and no double membrane bound organelles such as nucleus or mitochondria.
These organism have no separation between cytoplasm and nucleoplasm and all genetical material is found inside the cytoplams itself. Archae and bacteria are two distinct domains of life that comes under prokaryotes.

C. Archaeological surveys are only conducted during evaluations for cultural resource management (CRM) projects
D. Surface surveys are conducted directly after excavations to assess overall damage(s) to a site
Answer:
The correct option is A.
A. Small test pits can be conducted in an undisturbed part of the surveyed area to find buried artifacts that may not be readily seen on the surface.
Explanation:
This is because archeological survey refers to the study , exploration and digging of sites to obtain archeological remains. The basic sim of this is to get remains that are not visible to man underneath.
usually , the sites are dug out by a shovel so as to determine whether the soil contains any archeological emains that cannot be seen on the surface. This involves the action of excavating the out something or remains especially an archaeological site.
True or False: Decomposers do NOT need energy to live.
A. True
B. False
Answer:
False
Explanation:
Consumers (animals) get their energy by eating the producers and/or other consumers. Scavengers and decomposers get their energy by eating dead plants or animals. Living organisms require these nutrients to create cells, tissues and to provide energy for life processes. Thus, all living things need energy to survive.

Answer: Muscle cells and nerve cells (neurons) are two very different types of cells. Muscle cells (myocytes) contract to produce movement while nerve cells send messages from receptor cells to either glandular cells or muscle cells relaying messages throughout the body.
Muscle cells and nerve cells (neurons) are very exceptional kinds of cells.
Muscle cells (myoc ) to provide motion at the same time as nerve cells ship messages from receptor cells to both glandular cells or muscle cells relaying messages during the body.For example, a muscle cell makes use of the DNA that specifies the muscle apparatus, while a nerve cell makes use of DNA that specifies the fearful system.What are the Neurons?Neurons (additionally known as neurons or nerve cells) are the essential devices of the mind and fearful system, the cells accountable for receiving sensory enter from the outside world, for sending motor instructions to our muscles.
