The S phase is critical in the cell cycle because it indicates the cell is ready for division.

The correct answer is S phase.

The critical phase of cell cycle is S phase, in this phase the DNA starts replicating.The cell cycle is called the synthesis phase because the synthesis of DNA starts in this phase. There is no chance that the cell can go back to the previous phase. The DNA within the cell starts replicating. Depending upon the level of nutrients, energy and external factors, cells must decide that they will enter into cell cycle or not.

All evolutionary changes that allow a species to change in response to the environment, are originally a result of
Norma-Jean [14]
All evolutionary changes that allow a species to change in response to the environment, are originally a result of beneficial DNA mutations.

Beneficial genetic (DNA) mutations are result in individuals with special characteristics that allow them to survive better in the environment so they pass their genes to the next generation.

Here's a fictional example I made just for you!: Lets say you have an alien species called Hibas. They are jelly blobs that float around, don't move, and open their mouths to capture neon shrimps that happen to swim into their mouths. But one day a certain Hiba developed some muscles through a genetic mutation. It was able to "wiggle" through the water and steer itself instead of floating around. This allowed it to eat more neon shrimp than the other Hibas, so it grew faster and was able to reproduce faster. It's kids also had muscles and had an advantage so they reproduced faster then the other Hibas. Eventually the whole Hiba species started to have muscles because the ones that didn't weren't able to compete and did not survive as well. 
The reason that most of the Hibas developed muscles was because one of them had a mutation that allowed it to have muscles. This was a BENEFICIAL mutation that allowed it to SURVIVE BETTER.

When a plant is genetically identical to its parent plant what is this called
tamaranim1 [39]

Hello! My name is Zalgo and I am here to help you out on this amazing day. The way that the younger plant looks the same as the parent plant is because of "Asexual Reproduction". Asexual Reproduction is how plants can reproduce. Considering it is a plant and not a human asexual means that plants reproduce without the need of "sexual intercourse".

I hope that this helps! :P

kirill115 [55]
Sucrose: glucose + fructose sucrose is a disaccharide made from glucose and fructose
glucose: C(sub 6)H(sub 12)O(sub6)fructose: C(sub 6)H(sub 12)O(sub6)sucrose: C(sub 12)H(sub 22)O(sub 11)a water molecule, H(sub 2)O gets removed which is why there are 2 less hydrogens and one less oxygen
