Skin cells are also called epithelial cells
Decomposers because they decompose dead organisms, which releases the carbon.
Answer:
a. movement can occur both upward and downward in the plant
Explanation:
The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.
Answer:
The correct answer is statement d.
Explanation:
In oxidative phosphorylation that takes place in mitochondria, the uncouplers prevent the coupling in between the phosphorylation reactions and electron transport, and therefore, prevent the synthesis of ATP without influencing the ATP synthase and respiratory chain.
The uncoupler always exhibits its influence on the synthesis of ATP. The 2,4-dinitrophenol functions as an uncoupler at the time of oxidative phosphorylation. The NADPH and FAD functions as an electron carrier.
Answer:
AZT is a thymidine analog
Explanation:
Azidothymidine (AZT) is an antiviral drug used for the treatment of the Human immunodeficiency virus infection (HIV/AIDS) by preventing the transmission of HIV from infected cells. AZT is capable of suppressing the activity of the enzyme reverse transcriptase of the retroviral HIV genome, which enables it to copy RNA into DNA. In infected cells, this double-stranded DNA is integrated into the host genome which is then instructed to produce identical HIV copies. AZT is a thymidine analog that is incorporated into DNA and thus interferes with DNA synthesis, thereby inhibiting cell proliferation.
