Answer:
D: Simple Diffusion
Explanation:
Diffusion is a transport driven by a concentration gradient. Gas molecules move from a place of high concentration to an area of low concentration. Knowing when blood is low in concentration and high in carbon dioxide it goes under gas exchange with air into the lungs.

Answer:
The correct answer is: simple squamous epithelium.
Explanation:
The epithelium is one of the four basic tissues found in the body, along with the connective tissue, the muscle tissue, and the nervous tissue.
Epithelial tissue is commonly found surrounding surfaces such as the skin, and also making up the inner lining of hollow organs such as the ones that form the gastrointestinal tract.
<u>The number of layers and the shape of the cells in the epithelium have a direct correlation in the function of the tissue.</u> Functions can vary a lot from organ to organ, from absorption to protection and everything in between.
<u>A</u><u> simple squamous epithelium</u><u> is composed of a single layer of flat cells, which makes it permeable to liquids and small molecules, an important feature in organs where filtration or diffusion is needed; for example: capillaries and alveoli</u>.
Answer:
The correct option is A) will make no difference in the survival of life if there were major changes in the environment.
Explanation:
Due to genetic diversity, variations in species are caused which makes some organisms of a species to be better adapted than other members of the species. These variations cause organisms to survive when differences in the environment occur. Although the allele frequencies might change due to the changes in the environment but the phenomenon of genetic diversity allows life to sustain on earth even when conditions will become unfavourable.
I think it is C, but I could be wrong because I am taking an educated guess.
