Nope
summer is because the earth gets closer to the sun...and winter is because the earth is farther from the sun...you need to know that the earths revolution around the sun is not a perfect circle ... it is an oval rotation...

hope this helps

How can amino acids be use to maintain the blood pH?

Mars2501 [29]

Answer:

See the explanation below. Thanks!

Explanation:

The structure of an amino acid allows it to act as both an acid and a base. An amino acid has this ability because at a certain $pH$ value (different for each amino acid) nearly all the amino acid molecules exist as zwitter-ions. If acid is added to a solution containing the zwitter-ion, the carboxylate group captures a hydrogen ( $H^+$ ) ion, and the amino acid becomes positively charged. If base is added, ion removal of the $H^+$ ion from the amino group of the zwitter-ion produces a negatively charged amino acid. In both circumstances, the amino acid acts to maintain the pH of the system—that is, to remove the added acid $(H^+)$ or base $(OH^-)$ from solution.

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

Oksanka [162]

Answer:

Differentiate between tricuspid valve and bicuspid valve
