Explanation:
Plant cells are different from animal cells because they are usually -
Answer:
Plant cells have a large, singular vacuole that is used as a storage and to maintain the shape of the cell. Even though animal cells have vacuoles, they are smaller. Plant cells have a cell wall and a cell membrane. Animal cells only have a cell membrane, and no cell wall.
Explanation:
Please also describe how actin-binding sites are made available for cross-bridging with myosin heads during contraction.
Answer: The calcium ion binds to troponin, and this slides the tropomyosin rods away from the binding sites.
Explanation:
Contraction and relaxation of muscle cells brings about movements of the body. The contractile myofilament called sarcomeres are bounded at each end by a dense stripe called the Z - line, to which the myosin fibres are attached, and lying in the middle of the sarcomere are the actin filaments, overlapping with the myosin.
When action potential spreads from the nerve along the sarcolemma (muscle cell membrane), it penetrates deep into the muscle cell through the sarcoplasm (cytoplasm of muscle cell), and releases CALCIUM from the intracellular stores.CALCIUM triggers the binding of myosin to the actin filament next to it forming CROSS BRIDGES.
For this to occur, ACTIN BINDING SITE has to be made available. TROPOMYOSIN is a protein that winds around the chains of the actin filament and covers the myosin-binding sites to prevent actin from binding to myosin. The first step in the process of contraction is for calcium ions to bind to troponin so that tropomyosin can slide away from the binding sites on the actin strands.

Describe the structure of the conjugated protein
haemoglobin, with reference to the levels of protein
structure.
Answer: Answer below, hope this helps! :D
Explanation:
A conjugated protein is a protein that functions in interaction with other (non-polypeptide) chemical groups attached by covalent bonding or weak interactions. ... The non-amino part of a conjugated protein is usually called its prosthetic group. Most prosthetic groups are formed from vitamins. Hemoglobin is a protein having a globular structure. Based on its structural properties, hemoglobin can be divided into two parts; a protein part and a heme group. The structure of the protein part can be studied at four levels; primary structure, secondary structure, tertiary structure, and quaternary structure.

At what points in the progression from gene to protein do these methods act (i.e., what processes do they prevent)
Answer:
Genes are translated, transcribed and after these two steps, the formation of a protein takes place.
DNA is translated, that is, read, in the form of codes and thanks to the machinery of intracellular transcriptases, after this an RNA is encoded that will be made with the assembly of amino acids that together will form proteins.
Proteins can be structural or functional.
Explanation:
There are different methods to intervene in these processes, it can be by means of macromolecules, drugs and also by microbiological factors, that is, by microorganisms such as viruses that take advantage of the human transcription machinery to replicate.

Which of the following environmental parameters would be important to monitor in order to ensure sustainable logging?
A. The number of trees cut down versus number trees burned
B. The number of new trees planted to replace those removed
C. The number of trees needed to increase soil fertilization
D. The number of trees removed within a single species
Answer:
B. The number of new trees planted to replace those removed
Explanation:
Because to ensure that logging is sustainable, they have to sustain a certain ratio of trees cut down, to trees planted. D. The muber of trees removed within a single species could be right, but I think B is more right.
If you get this wrong you can blame it on me.

What's the definition of absoulute dating
Absolute dating is the process of determining an age on a specified time scale in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies an unwarranted certainty and precision. Absolute dating provides a numerical age or range in contrast with relative dating which places events in order without any measure of the age between events. In archeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates. Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped charge dating methods such as thermoluminescence dating of glazed ceramics. Coins found in excavations may have their production date written on them, or their may be written records describing the coin and when it was used, allowing the site to be associated with a particular calendar year.

what are the reproductive systems of insects?
Hey! Your answer to this question..
What are the reproductive systems of insects?
Insects that’s is female can make eggs, receive and store sperm, manipulate sperm from different males. They can also lay eggs of course. Insects reproductive systems are made of a pair of ovaries, accessory glands, one or maybe even more spermathecae, and lastly ducts connecting these parts. The ducts and spermathecae are line with a cuticle.
tRNA molecules deliver amino acids to ribosomes where the amino acid next
A. forms an ionic bond with another amino acid
B. is deaminated and catabolized
С. becomes an anticodon
D. is covalently bonded to a growing polypeptide
E. forms hydrogen bonds with esters
Answer:
tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).
Explanation:
A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.
What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.
tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.
During translation tRNA, molecules deliver amino acids to the ribosome and bind to this codon. It is a complementary anticodon to this codon.
Each tRNA molecule has two distinct endsone end binds to a specific amino acidthe other which binds to the corresponding mRNA codon. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.Thus, tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.

In those parts of equatorial Africa where the malaria parasite is most common, the sickle-cell allele constitutes 20% of the b hemoglobin alleles in the human gene pool. In the United States, the parasite that causes malaria is not present, but African-Americans whose ancestors were from equatorial Africa are present. What should be happening to the sickle-cell allele in the United States, and what should be happening to it in equatorial Africa
Answer:
directional selection, stabilizing selection
Explanation:
Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.
