Answer:
Option D
Explanation:
The species probably has a small genome that is made up just two linear chromosomes such as that seen in the Jack jumper ant genome. It containing exactly two linear chromosomes could be a single pair of homologous chromosomes thus maybe indicating the cell is probably diploid but this is not enough to conclude on the ploidy.
Answer:
Explanation:
1. charge in trypsin
: two other molecules in elastase
2. Chymotrypsin cleaves peptide bonds after bulky or aromatic side chains, such as those of the amino acids phenylalanine or tyrosine. The specificity pocket, or substrate-binding site, is deep and has hydrophobic side chains.
Trypsin cleaves peptide bonds following basic amino acid side chains. Lysine and arginine both have basic amino acid side chains that are positively charged at pH 7. Trypsin's substrate-binding site contains a negatively charged amino acid residue.
Elastase cleaves peptide bonds after amino acids with small side chains, such as glycine, alanine, or valine. The specificity pocket for elastase has bulky side chains that block larger amino acid side chains, but can accomodate smaller side chains, such as the -H, -CH3, and -CH(CH3)2 side chains of glycine, alanine, and valine, respectively.
3. Their binding pockets
- trypsin = long & (-) D on bottom
- chymotrypsin = deep & wide
- elastase = aliphatic a.a. = shallow
Receptors that are embedded on the cell membrane bind to chemicals outside of the cell and this binding process cause a chemical response on the inside of the cell.
These receptors that help in communication between the cell and the outside world are called cell surface receptors or sometimes transmembrane receptors.
A majority of chemical signals are water soluble thus unable to cross the fatty lipid bi-layer of the cell membrane. Their receptors, which are protein in nature therefore must span the membrane, detect their presence outside of the cell and transmit this information into the interior of the cell.
Answer:
vulnerable, endangered, critically endangered, and extinct in the wild and Extirpated.
