Answer:
The correct answer is: deposition of interferon on bacterial cells.
Explanation:
Phagocytosis is the mechanism by which a cell uses its plasma membrane to ingest a big particle, forming a phagosome within the cell. It's a form of endocytosis used by the <u>immune system to eliminate pathogens such as </u><u>bacteria </u><u>and cell debris</u>.
Phagocytosis can be enhanced through various ways when an infection is taking place in the body. For example, cytokines and TNF are secreted by different kinds of cells to stimulate this process - for these cytokines to be released, certain parts of the bacteria called PAMPs need to be recognized by specific receptors located in phagocytes and epithelial cells called TLRs. Another way to stimulate this mechanism is by depositing complement fragments on bacterial cells, which is done thanks to the Complement cascade, a system of great importance in the innate immune response against extracellular bacteria - these fragments will opsonize ("mark") the pathogens for the phagocytes to recognize them and engulf them.
Interferon, on the other hand, while hugely important on the immune response against viruses and other pathogens that infect our cells by entering them and using their organelles to replicate and translate proteins, is not an enhancer of phagocytosis, as it is mostly involved in the translation of genes that will lead to the infected cell's death.
Answer:
None of the organisms have the same number of difference from the human Cytochrome C. In situations like this, we can decide which is more closely related to humans by comparing anatomy structures, evolutionary tree or comparing them to the human genes by using another protein.

Answer:
D. At a rift valley the crust splits allowing basaltic magma to flow out without the force of a volcanos.
Explanation:
A. is a an illustration of a mid Atlantic ridge. Underseas volcanos form along the mid Atlantic and other Mid Ocean ridges. Some like in Iceland reach the surface.
B. Is an illustration of a hot spot volcano. These types of volcanos have formed the Hawaii islands. The island of Hawaii has an active volcano due to the action of a hot spot.
C. Is an illustration of a subduction zone. The heat and pressure that results from the ocean plate being pushed and pulled under a continental plate results in volcanos. Mt. St Helens is an example of volcano that results from a subduction zone.
D. is the correct answer, In a rift valley the magma can flow out through the break in the crust without forming a volcano. Western Oregon has vast lava beds of basaltic lava. There are no volcanos that were the source of these horizontal layers of lava.
The answer is C.) Use a fan instead of air conditioning
