<em>Answer:</em>
<em>Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait. One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin.

Answer:
C) traits cannot be chosen willfully, but are randomly inherited by our parents
The answer is:
False
Here is why:
What makes this statement false is "mouth." Polypeptide digestion starts in the stomach and it ends in the small intestine, in the duodenum to be more specific. Polypeptides cannot be directly absorbed by the body, so they are broken down into either individual amino acids, dipeptides or tripeptides so they can be absorbed.
Answer:
a. phagocytic blood cells - 9. microphages
b. stems cell that differentiate into fibroblasts - 4. mesenchymal cells
c. create matrix of connective tissue - 1. fibroblasts
d. secrete pigment melanin - 5. melanocytes
e. cause inflammation - 7. mast cells
f. second most abundant cell type and maintain matrix - 2. fibrocytes
g. specialized cell of the immune system - 8. lymphocytes
h. large phagocytic cells of the immune system - 6. macrophages
i. fat cells - 3. adipocytes
Explanation:
Almost all of these cells have one thing in common: they are part of the connective tissues in our body. Connective tissue can be <u>divided into two</u>: proper connective tissue (that can be loose or dense) and specialized connective tissue (in this category, for example, we can find blood tissue, adipose tissue, bone tissue, and cartilage tissue).
Cells in our bodies have very different but important functions and they partake in their tasks because of the specific tissue or organ where they are at. While <u>blood tissue has cells that specialize in gas transport and immune response</u>, the <u>connective tissue has cells that synthesize and maintain the matrix and also specialized immune cells as well</u>. Microphages, macrophages and lymphocytes can be found both in the blood tissue and the connective tissue as well, as they migrate from the bloodstream to the tissue where they are needed to perform immunity tasks. Also in the connective tissue, we can find other cells that participate in the immune response, like the mast cells that release histamine to produce inflammation.
<span>Professor Kwang Jeon observed that some amoebas in his invaded amoeba colonies survived thanks to changes made by the invading bacterias. This comfirmed the endosymbiotic theory that organells are formerly invading free living prokaryotes forms that were integrated and swallowed by others to form a new living unit.</span>
