Answer:
acetyl CoA
Explanation:
Pyruvate and fatty acids enter the mitochondrion (bottom) and are broken down to acetyl CoA.
Answer: The given statement is True.
Gene can be described as the segment of DNA ( deoxyribonucleic acid), which codes for a particular protein. The protein thus formed, corresponds to a specific trait ( such as skin color, hair color, color of eye) of the individual organism.
They possess set of instructions for making a protein in the form of nucleotide sequences. Gene undergo transcription to form mRNA ( messenger RNA), which is then converted into particular protein through translation.
Genes are inherited from parents by their offspring and in this way specific traits are inherited by offspring from their parents.
Thus, given statement in the question is correct.
Answer:
The answer is <em><u>D.
</u></em>
Explanation:
Viruses can evade the processing and presentation of antigens, for example by interfering with the expression of MHC class I proteins, although this increases their susceptibility to be detected by natural killer cells (NK). However, some members of the herpesvirus, papillomavirus, retrovirus, poxvirus and flavivirus families have also developed strategies to escape the attack of NK cells and promote their survival, inhibiting cell apoptosis. Finally, some pathogens often change surface antigens frequently, as in the case of influenza viruses (orthomyxovirus).
The human immunodeficiency virus (HIV) affects CD4 + T cells and degrades the host's ability to counterattack with a strong cell-mediated immune response. There are so many tactics of immune evasion used by HIV, which have so far hindered the development of an effective vaccine.
Answer: option C) cowpox and smallpox are caused by the same virus
Explanation:
Cowpox is a skin disease that affects cattle. It is caused by an Orthopoxvirus, with lesions occurring principally on the udder and teats of the animals.
Human infection may occur from touching infected cows, and thus giving immunity to smallpox (an acute infection caused by the same poxyvirus, in HUMANS)
So, Jenner's successful use was because cowpox and smallpox are caused by the same virus
the Nucleus
Explanation:
Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid). The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information.
