Use ohm's law to find the voltage needed to make a current of 3 a in a resistance of 9 ohms.

27 volts

Explanation:

According to Ohm's Law

V=IR

where V is voltage I is current and R is resistance

V=3*9

V=27 volts

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.
