Answer: Option A) sister chromatids
In mitosis, each chromosome is made up of sister chromatids that carry the same alleles.
Explanation:
During the fourth phase of mitosis (Anaphase) the sister chromatids part company and migrate to the opposite poles, each with the same alleles since no crossing over occurred.
Thus, mitosis results in two daughter cells that have the same chromosome make-up as the original parent cell.
I believe the answer is DNA or Deoxyribo Nucleic Acid
The gall bladder provides bile salt.
The gall bladder is a small pear-shaped organ that is located at the abdomen inferior to the liver.
This organ stores and releases the bile salt produced from the liver.
The bile salt is released through the bile duct into the duodenum of the small intestine.
The bile salt is use to emulsify fat thereby aiding it's transport across the intestinal membrane.
Therefore, the gall bladder provides bile salt that aids in transport of lipids across the intestinal membrane.

Almost positive that it's option C, because ultraviolet rays indeed do that, i'm not good with the study of x-rays but i'm sure it doesn't go with #3.
The right answer is Nutrition
This answer can not be digestion nor absorption because it is a term that concerns multicellular beings.
Digestion is a mode of mechanical and chemical transformation of food nutrients assimilable or not by the body. By definition, digestion is a process present in all heterotrophic organisms. This digestion is carried out in a digestive system that can correspond to a simple digestive vacuole of a eubacterium, or specialize as is the case of mammals ruminants (cow, etc.). Digestion can also be defined as the molecular simplification that is to say the transformation of macromolecules (large molecules) into micromolecules.
Nutrition is therefore the most adequate answer.
By cellular nutrition is therefore meant the provision of the nutrients necessary for the proper functioning of each human cell. It is therefore to give the cells all the micronutrients at higher or optimal doses, that is to say in amounts beneficial to health. In other words, it is essential that our dietary supplementation be balanced and complete, as is a healthy diet.
