Usually the body needs to excrete excess acid. sometimes, however, the body is in alkalosis. in the collecting duct, there are s
nadezda [96]

The type b intercalated cells will reduce the amount of bicarbonate ion secreted and the amount of hydrogen ions excreted by the body in order to deal with alkalosis.

<h3>What is alkalosis?</h3>

Alkalosis is a condition in which excess alkali is present in the blood.

Alkalosis occurs when the body exceeds excess alkali in from the body.

Therefore, the type b intercalated cells will reduce the amount of bicarbonate ions secreted and the amount of hydrogen ions excreted by the body in order to deal with alkalosis.

A population of fruit flies where wing shape is determined by one pair
AVprozaik [17]

The value of 2pg in the given population is 0.432

<u>Explanation:</u>

Given:

C is normal

c is curly wings

So the homozygous dominant condition would be CC

Heterozygous condition would be Cc

Recessive condition would be cc

According to Hardy Weinberg principle,

p² + 2pq + q² = 1

and

p + q = 1

Here,

q² = cc = 100

q² = 100 / 1000

q = √0.1

q = 0.316

So,

p + q = 1

p + 0.316 = 1

p = 0.684

Thus, 2pq would be:

= 2 X (0.684) X (0.316)\\\\= 0.432

Therefore, the value of 2pg in the given population is 0.432

The ​ DNA molecule is very similar among all living things. The pairings are always the same and there are only six components t
Gala2k [10]

Answer:

The reason why there is so much diversity of life, despite the fact that DNA is the same for all living things, the pairings are always the same and there are only six components that make up the DNA, is that sequences of base pairs are different.

Explanation:

DNA is the molecule that contains all the genetic information, whose structure consists of four nitrogenous bases, adenine, guanine, thymine and cytosine, plus deoxyribose and a phosphate group. This DNA molecule constitutes the basis of life and inheritance of all living beings.

The nitrogenous bases of DNA are found in a number and specific sequences, which determine the proteins and biomolecules that must be synthesized in the cells.

What makes different types of living beings and diversity of life is the length of the DNA and the sequence of bases that form part of each molecule.

The other options are not correct because:

  • <em>The sugar component of DNA is always the same, not different. </em>
  • <em>Organisms always use DNA in the same way. </em>
  • <em>The DNA molecule is always the same.</em>
