Answer:
B. It inhibits the extrinsic pathway of apoptosis
Explanation:
Apoptosis is a cellular pathway that leads to programmed cell death. Viral FLICE-inhibitory proteins (FLIPs) bind to the adaptor proteins and block the interaction between the DISC complex with the caspase-8 protease enzyme, which triggers apoptotic cell death. In consequence, cells become resistant to Fas-mediated apoptosis, a pathway initiated by the FADD protein which is known to recruit caspase-8.
Structure of the inner ear responsible for hearing: the cochlea
Structure of the inner ear responsible for balance: semicircular canals and the vestibule
The resulting population has lower genetic variation.
Explanation:
A population bottleneck from the graph shows the sharp reduction in population of cheetah.
This could have been due to natural disasters, genocides or diseases.
The reduction in population caused reduction in variation of gene pool.
The population thus have small genetic variation.
The gene flow can only be increased by immigration or mutation
Bottleneck in cheetah is explained as narrowing of gene pool when large numbers of cheetah dies leaving small population with less genetic variation.
<span>It is called the Growth hormone deficiency, a medical condition due to insufficient growth hormone. The common symptoms is a short height, low blood sugar in newborns, and decreased muscle mass, high cholesterol levels and poor bone density in adults.<span>

Answer:
Lipids: Carbon, Hydrogen and Oxygen - monomers are glycerol and fatty acids.
Proteins - Carbon, Hydrogen, Oxygen and Nitrogen - monomers are amino acids
Carbs - No Phosphate. Carbon, Hydrogen and Oxygen - H:O ratio is 2:1 - monomers are (may have a ring structure)
Nucleic Acids - Examples are DNA and RNA. Carbon, Hydrogen, Oxygen, Nitrogen and Phosphate - monomers are nucleotide (sugar, phosphate, nitrogen base)
Lipids and proteins contain carbon, hydrogen, and oxygen. Both monomers are from certain types of acids. Carbs also contains carbon, oxygen, and hydrogen like lipids and proteins do. Carbs have monomers. Nucleic acids contain the same things founds in all three major macro molecules. Nucleic acids have nucleotide.
