Answer:
Only P-, F-, and V-class pumps transport ions.
Explanation:
The distinct classes of ATPases include:
1) Only the P-type ATPase actively transports ions across biological membranes. P-ATPases (also named E1-E2 ATPases) are found both in plasma and organelle membranes. These ATPases serve to transport ions and phospholipids by hydrolyzing ATP to ADP and phosphate.
2) A- and F-ATPases synthesize ATP by transforming the energy from a gradient of ions across the cell membrane.
3) V-ATPase (also known as Vacuolar-H+ ATPases) acidifies vacuole, lysosome, endosome and Golgi membranes. This type of ATPase couples the hydrolysis of ATP to the active transport of protons across biological membranes.
4) E-ATPases hydrolyze extracellular ATP.
False The cell cycle is a repeating series of events that includes growth, DNA synthesis, and cell division
<h3>What is cell cycle ?</h3>
During a cell's growth and division, a set of processes known as a cell cycle occur. In what is known as interphase, a cell spends the majority of its time expanding, replicating its chromosomes, and getting ready to divide. Following the cell's exit from interphase, it goes through mitosis to finish dividing.
- These are the prophase, prometaphase, metaphase, anaphase, and telophase phases. It is sometimes referred to as the sixth phase of mitosis since cytokinesis is the final physical cell division that occurs after telophase.

Answer:
males have one X and one Y chromosome.
Explanation:
Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.
Answer:
Explanation:I will explain briefly By combination mapping
For example two genes
H/h = T/t
Therefore, parental HT will dominate more than ht
The genetic patterns I described above are for the ideal situation where there is no ambiguity in the determination of chromosomal location.
