When the sand hits the still water it sinks, because there is not enough current
G1 is the cell growth phase where the cell accumulates nutrients and decide if it is going to undergo the cell cycle, as determined by the restriction point in G1. If the cell has insufficient nutrients or has not grown sufficiently to enter the cell cycle, it will remain in G1 or exit to G0 phase where it will not divide.
G2 occurs after S phase DNA replication in the cell cycle. In G2, the cell is growing and preparing for cell cycle by producing proteins required such as the centrosome.

Answer:
Telophase
Explanation:
During telophase, a nuclear envelope becomes apparent around the nucleolus of each sister chromatid, forming their nucleus before separation/cytokinesis.

Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.
Answer:
<h2>
All the gametes are 25%; SY(25% so on) Sy, sY, and sy .
</h2>
Explanation:
Spherical shape (S) is dominant over dented shape(s), so S is dominant over s;
Yellow (Y) is dominant over white color (y), so Y is dominant over y.
Here as given, parent is heterozygous for both parents.
so its genotype is= SsYy
Gametes formation follow both law of segregation and law of independent assortment:
So, 25% of gametes are SY
25% of gametes are Sy
25% of gametes are sY
25% of gametes are sy.
