The best choice is A.
A gene is a specific sequence of nucleotides in DNA or RNA that is located usually on a chromosome and that specifies the structure of a particular polypeptide and especially a protein, or controls the function of other genetic material.
Information from the gene is copied (transcribed) on mRNA in the nucleus. mRNA then leaves the nucleus and enters the cytoplasm where it attaches to a ribosome. The information on the attached mRNA is decoded (translated) by tRNA which then fetches the amino acids according to this information and brings them to the ribosome where they are linked together to form the specified protein.

Answer:
The correct answer is - Homeostasis requires balances between many factors in the body such as the body temperature, chemical and physical balance, pH etc
Explanation:
Homeostasis is the ability of an organism to regulate or maintain its internal environment or conditions according the condition require for survival of organism or cell.
It is the characteristic feature of living organisms and life to adapt or maintain the equilibrium of cell's chemical, physical environment.

<h2>Answer is option "B"</h2>
Explanation:
- Opportunistic infections (OIs) are diseases that happen all the more frequently or are progressively extreme in individuals with debilitated resistant systems than in individuals with sound invulnerable systems. Individuals with debilitated resistant systems incorporate individuals living with HIV
- OIs are brought about by an assortment of germs (infections, microbes, organisms, and parasites). OI-causing germs spread in an assortment of ways, for instance noticeable all around, in body liquids, or in tainted nourishment or water
- On account of endogenous contaminations, we become tainted with our own microbes, our own microflora. This may occur if an obstruction among sterile and non-sterile tissues is broken, for example, with an entrail aperture.
- A patient with an undermined invulnerable system, for example, after chemotherapy, may get wiped out from a microbes effectively present in his/her body that becomes unchecked. A lethargic pathogen may likewise become reactivated and contaminate the host, for example, on account of tuberculosis
- Hence, the right answer is option B " Opportunistic, endogenous pathogen"
