a human skin cell contains 46 chromosomes. A frog sprem cell conrains 12 chromosomes. which paie of number of a normal gamete from each of these species

Answers

Answer 1

Answer: Human 23, frog 12
Because gametes contain half the number of usual chromosomes, so a human gamete would have 46/2 or 23 chromosomes. A frog sperm cell is a gamete so it would have 12 chromosomes anyway.

Hope this helps :)

d. pressure

Answers

Ocean tides are caused by the gravitation of the Moon. Currents can beformed by the flow of tidal water around the continental plates, or by adifference in water temperature between large ocean areas. Surfacewaves are caused by the wind. Abnormal waves can be created by thetectonic movement of plates around and under the ocean floor (tsunamis).So as you can see, the answer is (C) Gravity

The image below shows a cell in one of the stages of cell division.Which of the following statements correctly describes the stage in cell division shown in the image? (Look at the image attached for clarification)

Answers

The statement that correctly describes the stage in cell division shown in the image is the cell is in telophase II of meiosis because the cell is separating and contains two copies of each chromosome. The correct option is D.

What is cell division?

The process by which new cells are created from more mature cells is known as cell division. Each and every eukaryotic cell engages in this process. There are various steps in the procedure. Every component of the cell is split into two during the process, which results in the creation of a duplicate of the original cell.

Telophase is the last stage of cell division. In this stage, the material in the cell is divided and in this step, the plasma membrane divides and separates the two cells.

Thus, the correct option is D. the cell is in telophase II of meiosis because the cell is separating and contains two copies of each chromosome.
