After which checkpoint is the cell first committed to continue the cell cycle through M?

Biology
1 answer:
Viktor [21]3 years ago
8 0

The correct answer is: B) G1

Normal cells (unlike cancer cells), move through the cell cycle in a regulated way in order to make sure that cells don't divide under conditions that are unfavorable for them. Information about their own internal state (nutrients, signal molecules, DNA integrity) is signal to go or not to go through the cell division. Because of that there are few checkpoints in the cell cycle at which the cell examines the signals and makes a “decision”. The major checkpoints are:

• The G1- the first point at which it must choose, once it passes the G1 checkpoint the cell enters S phase

• The G2-the cell checks DNA integrity and checks if replication is done well.

• The spindle checkpoint-at the transition from metaphase to anaphase.

———— creates the skin-like surface formed due to the polar nature of water??
Cerrena [4.2K]

Answer:

Cohesion is the correct answer

Explanation:

Water molecules are held together by hydrogen bonds. Water molecules stick to other water molecules. Surface Tension. Creates the skin-like surface formed due to the polar nature of water.

Water is sticky because of hydrogen bonds. Water has a remarkable capacity to hold to itself and other objects. The capacity of water molecules to be attracted to other water molecules, allowing water to be a "sticky" liquid, is described by the Characteristic of cohesion.

(hope this helps can I pls have brainlist (crown) ☺️
