Answer:
Osmosis is the diffusion of water molecules, from a region of higher concentration to a region of lower concentration, through a partially permeable membrane. A dilute solution contains a high concentration of water molecules, while a concentrated solution contains a low concentration of water molecules.

There are choices for this question namely:
<span>a. ilium
b. pubis
c. ischium
d. sacrum
</span>
The correct answer is the "ilium". The pelvis is composed of 3 bones that fuse to make the pelvic girdle (with the sacrum). These bones are the ilium, ischium, and the pubis. The ilium forms the superior border of the pelvis, the ischium is the inferior, the pubis is the anterior, and the sacrum is the posterior. Attached is an image of the pelvic girdle, not that the ilium is at the superior portion of the pelvis.
Answer: DNA codes for our genotype, which is the genetic representation of out traits. There are multiple kinds of RNA but it is mostly used to aid the replication of DNA.
Explanation: DNA is the strand of nucleic acid, sugars and phosphate group, that is found in the nucleus and mitochondria of every cell. It codes for our genotype, which is essentially the written representation of our traits. There are multiple kinds of RNA but they are mostly used to replicate DNA, they are single stranded as opposed to the double stranded DNA and include the nitrogen base uracil (U), instead of thymine (T). mRNA, tRNA and dsRNA are commonly used to replicate and regulate the DNA sequence.
D) DNA is found in chromosomes in the nucleus, while RNA can move around the cell.
