Answer: d. all of the above
Explanation:
Chymotrypsin is produced by the Pancreas and has the function of digesting proteins.It consists of three polypeptide chains connected by two inter-chain disulfide bridges. Chymotrypsin exerts an important biological function which is the hydrolysis of proteins in the small intestine. The cleavage of peptide bonds is selective, occurring only on the carboxyl side of aromatic side chains of tyrosine, tryptophan and phenylalanine, and large hydrophobic radicals such as methionine. Chymotrypsin also hydrolyzes ester
The main reason that most farmers use stem cuttings rather than just planting a seed is that a tree's genetic variation will occur. The seeds of many fruit trees tend to vary differently from the parent, because seeds themselves are produced by sexual reproduction (i.e they receive genes from a male and female to form). As they are a cross from two sets of genes, many fruit trees are not “true to seed”. Their seeds will produce a generally different variety of tree from the parent. When using stem cuttings, it's almost like a cloning process.
the thylakoid will have fewer hydrogen ions
World pollution isn’t good
Answer:
5] Neutron: Charge= 0 Atomic mass unit = 1
10] <u>Hydrogen:</u>
Number of protons = 1
Number of neutrons = 0
Number of electrons = 1
Atomic number = 1
<u>Helium:</u>
Number of protons = 2
Number of neutrons = 2
Number of electrons = 2
Atomic number = 2
<em>Note:</em>
<em>Atomic number = proton number</em>
<em>Neutron number = Mass number - atomic number</em>
<em>Number of electrons = number of protons</em>
