Answer: Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).
Explanation:
Answer:
A
Explanation:
because when sun shines on water, it turns into heat and evaporate
At this point in time, we have yet to reach the carrying capacity for humans. So yes there is a carrying capacity for humans we just haven't reach it yet.
<span>1) Receptors are linked with sensory neurons that send any signals that the receptors pick up to the brain. If the signal requires some kind of response to maintain homeostasis, signals travel through motor neurons to effectors.</span>
<span>2) The organ that controls the regulation of body temperature is the hypothalamus while the process that allows us to maintain our core temperature is referred as thermoregulation.</span>
3) Controlling blood sugar levels with insulin is a negative feedback mechanism. Receptors in the body sense when blood sugar levels rise. To deal with that, the pancreas pumps insulin into the blood to lower it. Blood clotting is a positive feedback mechanism where platelets start to clump around an injury in a blood vessel and release chemicals that bring more platelets that end up doing the same thing to form a clot.
