#1. Typical United States weather patterns show the continental polar air mass moving south toward the Gulf of Mexico. Why does this air mass movement happen?
C) The polar air mass moves south to replace the rising maritime tropical air mass.
#2. Running a mineral across a porcelain plate to see the color it leaves behind on the plate may be described as testing for D) streak.
#3. D. Carbonization preserves soft tissues of plants or animals as a thin carbon film, usually in fine-grained shale sediments.
#4. We can divide natural resources into two basic categories: renewable and nonrenewable. Consider the bar graph of resource usage. If we wanted to reduce the use of nonrenewable natural resources, it would be least important to A) reduce deforestation.
#5. Nicolaus Copernicus was a Polish astronomer who is best known for the theory that the sun is near the center of the universe and that the earth and other planets revolve around it. Copernicus did not believe that the planets were influenced by or revolved due to the sun; instead he believed that the sun was located near the center of the universe and that it was this center which influenced those bodies and caused them to revolve. When this theory was first published, the scientific community did not accept it. Which reason BEST explains the reason for rejection of this theory?
C) It lacked sufficient evidence and explanation.

Phylum Porifera
The phylum Porifera ("pore-bearing") consists of approximately 5,000 species of sponges. These asymmetrical animals have sac-like bodies that lack tissues, and are usually interpreted as representing the cellular level of evolution
Answer:
B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.
Insertion mutation takes the T out and replaces it with an A.
