3
Where do light-independent reactions occur?
in the stroma
4

9
What is the end result of mitosis?
Two Identical diploid cells
10
End result of meiosis?
Four non-identical halfloid cells
11
Diploid cells have ___ chromosomes
46
12
Halfloid cells have ___ chromosomes
23
13
What is a checkpoint gene?
Monitor whether a cells DNA has been copied completely, whether its damaged, and whether enough nutrients are available. If a problem remains uncorrected, the checkpoint proteins may cause the cell to self-destruct and inhibit mitosis

Which stage creates the most ATP during aerobic respiration
electron transport phosphorylation (ETP)
24
How many chromosomes does an egg have?

25
How many chromosomes are found in body cells
46
26
If a tumor stays within its place it is
benign
27
If tumor spreads past its original spot it is

What splits during photosynthesis?
It splits H20 into oxygen, which is released, and glucose, which is absorbed for fuel)
34
What is the coronavirus?
an acute disease in humans caused by a coronavirus, which is characterized mainly by fever and cough and is capable of progressing to severe symptoms and in some cases death, especially in older people and those with underlying health conditions.

Aerobic respiration breaks glucose down into
ATP/energy and carbon dioxide and water
40
leptin and ghrelin
two hormones that play crucial roles in regulating appetite, energy balance, and body weight.
41
Insulin
a hormone produced in the pancreas by the islets of Langerhans, which regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes.
