Explanation:

A molecular clock determines evolutionary relatedness by examining how many mutations or random changes in DNA, there are between two organisms. When we map the relatedness of different organisms, we are creating a phylogenetic tree. At some point, all organisms that are alive today shared a common ancestor.

Which type(s) of cell division (mitosis, meiosis l, meiosis Il) reduce(s) the chromosome number by half? Which type(s) of cell d

PSYCHO15rus [73]

Answer:

Which type(s) of cell division reduce(s) the chromosome number by half?

Meiosis l

Which type(s) of cell division can be classified as reductional?

Meiosis I

Which type(s) of cell division can be classified as equational?

Mitosis and Meiosis II

Explanation:

Meiosis is a type of cell division which occurs in the germ or reproductive cells to produce gametes. It is completed in the two stages, meiosis I and meiosis II. The cells which are going to divide by meiosis are diploid having two sets of chromosomes. Meiosis I is the first stage of the meiosis. At the end of meiosis I two daughter cells are formed having only 1 set of chromosomes and chromosome numbers are reduced to half. Thus, meiosis I is a reductional division.

Mitosis and meiosis II is the equational division as after division chromosome number remains the same as in the parent.

This family of ATPases is structurally related to the pumps that acidify lysosomes and vesicles; however, they usually function

Vsevolod [243]

This family of ATPases is structurally related to the pumps that acidify lysosomes and vesicles; however, they usually function in reverse, generating ATP from ADP and Pi using proton gradients across membranes is called F-type pumps.

The inner membrane of mitochondria and bacterial plasma membranes both contain F type pumps, which are necessary for the generation of ATP.
It is also known as the ATP synthase complex or Complex V. By letting these protons passively return to the matrix, they use the proton gradient created by the flow of electrons to produce ATP.
The F1 motor is the ATP turnover motor and,
In mammals, the F0 motor, which is in charge of ion translocation, has nine subunits, nine of which are likely centered on the membrane's A, B, and C subunits, along with D, E, F2, F6, G2, and 8 subunits.
