Answer:
photosynthesis
Explanation:
Chlorophyll a absorbs the wavelengths of violet-blue and orange-red light and functions as a primary electron donor during the election transport chain in photosynthesis. It also functions in transporting energy to the reaction center where P680 and P700 are located.
It’s because 15ml was just under the range and 50ml is just over it. 30 is a happy middle.
Answer:Answer:
For 1: The correct answer is Model 1, 2, and 4.
For 2: The correct answer is Option 1.
Explanation:
For 1:
An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).
Atomic number is defined as the number of protons or number of electrons.
Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.
For 2:
A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example: is a compound made out of atoms of carbon and oxygen.
Hence, the correct answer is Option 2.
Tyrosine is listed as a non-essential amino acid because it can be synthesised from the essential amino acid phenylalanine.
<u>Explanation:</u>
Amino acids are classified as essential and non essential according to whether they can be synthesized in the body itself or should be supplied by the diet. Essential amino acids cannot be synthesized in the body of the organism and thus can be obtained only from the diet. In the case of human beings, valine, phenylalanine, methionine etc are examples of essential amino acids.
Non essential amino acids can be synthesized within the body of the organism. Thus they need not be supplied by the diet. Alanine, aspartic acid etc are some of the non essential amino acids in human beings. It is given here that animals cannot synthesize tyrosine from shikimate-3p due to the lack of EPSP synthase.
But the amino acid tyrosine can be synthesized from the amino acid phenylalanine which is an essential amino acid. Thus tyrosine will be a non-essential amino acid.
