B, Provide nutritional support to the embryo. It is not D, as the breasts are not part of the female reproductive system. It isn't C because during pregnancy, fetal and maternal blood do not mix. It also isn't D since women do not produce sperm.
Due to divergent evolution, some species may have similar anatomical structures with the same purposes. The species while not exactly similar are close enough to allow the interbreeding of the two, such as the horse and mule
The statement above is TRUE.
RNA hydrolysis is a reaction in which a phosphodiester bond in the sugar phosphate backbone of RNA is broken, thus cleaving the RNA molecule.
This reaction is made possible in RNA because the ribose sugar in RNA has hydroxyl group at the two prime position.
Robert Hooke observed the cells through a combination of lenses.
After Robert Hooke, the development of microscopy take place. After the development of the microscopy, scientist were able to observe the features of the cell. In order to formulate a cell theory observation of most of the cells was necessary. So, it was necessary to observe different types of cells from different organism. So, the advancement of the microscopy and observation process required for the formulation of the cell theory was the reason for the delayed development of the cell theory.
Answer:
One of the functional differences between the sympathetic and parasympathetic nervous system is that in the sympathetic nervous system first stage neurons have synapses a considerable distance from the target organ (Option C).
Explanation:
Sympathetic nervous system is part of the autonomic nervous system, and is responsible for producing the body's activating response, such as increased heart rate, pupil dilation, and increased muscle strength and endurance. The main neurotransmitters of this system are epinephrine (adrenaline) and norepinephrine.
<em>One of the fundamental characteristics of the sympathetic nervous system is its ability to release neurotransmitters even when they are far from the receptors, while the nerve ganglia of the </em><em>parasympathetic nervous system</em><em> must be close to the target organs.</em>
