Answer:
severe drought, since other are biotic factors.
Any light that exist was already emitted from somewhere. Any light that is absorbed, is destroyed, and is not emitted light; though, it may lead to light being emitted.
Answer:
2 base long codon
Explanation:
In the given question, the total number of amino acids is about 10 and the number of nucleotide bases is only two.
So these two nucleotides will be arranged in a maximum of 
as there are only two nucleotides and either each nucleotide will code for a single amino acid or in pairs of two it will code for specific amino acids. Therefore the maximum amino acid chain will be formed by the four bases of amino acids.
Thus, 2 base long codon will be correct.
Answer:
when G1/S cyclin-CDK is activated. Expression of G1/S cyclins is regulated by E2F proteins
Explanation:
I've found this on Google
Commitment to cell division occurs at Start when G1/S cyclin-CDK is activated. Expression of G1/S cyclins is regulated by E2F proteins in conjunction with pRB proteins.. Mitogens stimulated cell division by increasing the amount of G1 cyclins.
A. They receive energy from the wind
