D. cellular respiration and photosynthesis
Answer:
Anticodon. The anticodon region of a transfer RNA is a sequence of three bases that are complementary to a codon in the messenger RNA. During translation , the bases of the anticodon form complementary base pairs witht the bases of the codon by forming the appropriate hydrogen bonds.
Answer:huh I dunno what that is
Explanation:
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
An energy pyramid illustrates that energy in the form of heat is lost to the surrounding as it is passed from one organism to the next. In an energy pyramid energy is passed from one trophic level to the next, however, only ten percent of the energy in a given trophic level is passed to the next, as most of the energy is lost inform of heat to the surroundings.
