The incorrect statement is option (A) the innate defenses of the body apply strictly to external pathogens, while adaptive defenses apply strictly to internal pathogens.
Immunity can be classified into two types namely, the innate immunity and the adaptive immunity. Innate immunity is the first line of defense against the pathogens. It includes the physical and chemical barriers of the immune system along with the action of the phagocytizing cells called the macrophages. Whereas, the adaptive immunity is mediated by the cells of the immune system called the lymphocytes. The B lymphocytes produce antibodies and are responsible for humoral immunity. The T lymphocytes produce the cell mediated immunity with the production of the helper T cell, cytotoxic T cells and attack the pathogens. Innate immune response is comparatively a faster immune response which can be activated by any foreign substance entering the body. Both the defenses work on external and internal pathogens.
Gases trap heat and cause the greenhouse effect. Solar radiation warms the earth, while the atmosphere traps it.
Leads to seasonal patterns, when the earth is tilted to the northern hemisphere its summer and when the earth is tiled to the south, its winter.
Results in some of the atmosphere to be warmer than other parts, it changes in volume and pressure which results in strong weather.
As wind or ocean current moves, the Earth spins underneath it.
Melting of the ice mass at the poles, which causes rising sea level, producing flooding and endangering coastal habitats
Shock waves, heat radiation, the formation of craters with associated earthquakes, and tsunamis if water bodies are hit or caused by the earthquakes.
jeopardizing latitude, water elevation, ocean currents, topography, most habitats, and prevailing winds.
12) B. The organism would suffer as its cells would be less able to provide the energy needed to carry out life functions.
13) D. The central vacuoles in the cells lose water and can no longer help support the cells.
14) A. It acts as a framework inside the endoplasmic reticulum and keeps it from collapsing.
15) D. The cell's energy level will diminish as the enzyme decreases.
16) C. Whales are able to conserve oxygen better than humans.
17) A. Glycolysis
18) i dont know this one but maybe B

Answer:
As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses.

Answer:
Epistasis is a phenomenon in Genetics in which mutations on one gene locus are dependent on the mutations on some other genes locus. In other words, the expression of a phenotype of one gene is dependent on the presence or absence of mutations on other gene.
Dominance is phenomenon in genes in which a particular genotype masks the expression of alternative genotype and expresses itself due to complete takeover over other.
