The answer is
B) Evolution
Although the options are not provided, the statement best describing the relationship is nucleic acids provide blueprints for the construction of proteins.
Messenger RNA molecules (mRNA) take instructions from DNA molecules and take the code out of the nucleus. There, ribosomes work with the RNA molecules to produce a chain of amino acids, which in turn links and folds in a specific manner to form a protein molecule.
When
the morning announcements call for you to rise to recite the pledge of
allegiance, the signal to stand up on your feet is sent by the somatic nervous system. The somatic nervous system is <span>part of the peripheral nervous system. Its functions are : </span><span>voluntary movement of the muscles and organs and reflex movements. So, the signal to stand up on our feet in the morning is movement of the organs sent by this system. </span>
The answer is LDL (Low Density Lipoprotein)
Arteriosclerosis is the build up of cholesrol on the inner walls of the arteries. In the long run, arteriosclerosis reduces the diameter of the blood vessels, causing high blood pressure.
The endothelial cells of arteries have receptors that facilitate binding and transportation of the LDL hence facilitation of their accumulation in the blood vessels.
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.
