Answer:
D. People allow only organisms with certain traits to reproduce.
Answer:
Yes they show difference in their mobility due to the difference in their molecular weight.
Explanation:
GFP is green fluorescent protein and BFP is blue fluorescent protein that are used in recent molecular techniques. Gel electrophoresis can be used to understand the molecular weight of protein based on their mobility.
The GFP and BFP have 238 amino acids but two amino acids have been substituted that found in the GFP primary structure. The GFP band in G-Boil and BFP band in B-Boil shows different location. The substitution of two amino acids reduces the molecular weight of the protein. The protein with less molecular weight shows high mobility in the gel.
Hello, Boolinjennipa1afd. Neurons communicate with the cells that they are controlled by releasing chemicals, called neurotransmitters, at a synapse. Your answers would be - two neurons communicate with each other through the synapse (the site of the functional connection). The other answer would be - The neurotransmitter is released at the site to initiate action potential and carry the signal through the body. The neurotransmitter molecules then diffuse a very short distance to the cell being controlled, where they have a specific effect. If you have any more questions then feel free to let me know. Have a great day!!
Explanation:
Muscles can pull bones, but they can't push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. Then, when the movement is completed, the flexor relaxes and the extensor contracts to extend or straighten the limb at the same joint.
