Each oligodendrocyte forms one segment of myelin for several adjacent axons.Oligodendrocytes are found only in the central nervous system, which comprises the brain and spinal cord.
Answer:
C. Decrease Coal Consumption
Explanation:
I believe it would be C because Coal Consumption releases Carbon Dioxide into the atmosphere and if we decrease the amount of Coal Consumption, then we can decrease the amount of Carbon Dioxide released into the atmosphere.
I hope it helps! Have a great day!

B. they make ATP from glucose molecules and use when necessary
Answer:
Pancreas.
Explanation:
Pancreas may be defined as the merocrine gland that can acts as an endocrine gland as well as an endocrine gland. Pancreas releases the important hormone known as insulin and glucagon.
Sasha is a diabetic patient and cannot digest carbohydrate properly. Her pancreas is not working properly as the pancreas release pancreatic amylase that helps in the digestion of carbohydrate. The abnormal secretion of insulin hormone may cause diabetes that disrupts the level of carbohydrate in the body.
Thus, the correct answer is pancreas.
Answer:
recombination and independent segregation of chromosomes during meiosis
Explanation:
Recombination and independent segregation of chromosomes represent the two most important meiotic mechanisms by which sisters from the same parents can inherit different gene variants and therefore look very different from each other:
1- Independent assortment (segregation) of chromosomes: during meiosis, homologous chromosomes are randomly distributed in daughter cells (which will give rise to the gametes), and therefore separate independently of each other. It is for that reason that gametes have unique combinations of chromosomes, which increases genetic variation.
2- Recombination, also known as crossing over, refers to the exchange of chromosome segments between non-sister chromatids during meiosis. This mechanism is well-known to produce new gene variants (alleles) in the daughter cells. In consequence, recombination also increases the genetic variation of the resulting gametes that will produce offspring (in this case, different sisters).
