Answer:
The correct answer will be option-C
Explanation:
In anaerobic conditions or when the oxygen is limited, the pyruvate enters the anaerobic respiration.
During heavy exercise when the ATP is required in high amount then then oxygen is also required in high amount but due to lack of oxygen, pyruvate formed as a result of the glycolysis is converted to lactate. Lactate acts as electron acceptor taking the role of the oxygen.
This lactic acid diffuses into the blood plasma which is then carried to the liver. In the liver Cori cycle converts the lactate back to the pyruvate form or glucose form.
Thus, option-C is the correct answer.
A) the exchange of gases throughout the body
Answer: Yes the ozone layer sits at the top to protect us from harmful UV rays from the sun.
Explanation:
Answer:the correct option will be
The virus forced the monkey cell to make proteins for its envelope.
Explanation:Enveloped viruses contain nucleocapsids of either icosahedral (e.g. herpesviruses, togavirus) or helical symmetry (e.g. influenza). The outer envelope is a lipid bilayer derived from host cell membrane in which both viral glycoproteins and some host proteins are embedded.
Many enveloped viruses complete their replication cycle by forming vesicles that bud from the plasma membrane. Some viruses encode “late” (L) domain motifs that are able to hijack host proteins involved in the vacuolar protein sorting (VPS) pathway, a cellular budding process that gives rise to multi vesicular bodies and that is topologically equivalent to virus budding. Although many enveloped viruses share this mechanism, examples of viruses that require additional viral factors and viruses that appear to be independent of the VPS pathway have been identified. Alternative mechanisms for virus budding could involve other topologically similar process such as cell abscission, which occurs following cytokinesis, or virus budding could proceed spontaneously as a result of lipid microdomain accumulation of viral proteins. Further examination of novel virus-host protein interactions and characterization of other enveloped viruses for which budding requirements are currently unknown will lead to a better understanding of the cellular processes involved in virus assembly and budding.
The actual answer is D because risk factors are anything that increases the risk of someone getting sick or disease
