Answer:
D. They both decrease genetic variation.
Explanation:
In natural selection, variation happens to produce more fit organisms. The natural selection is a different type such as stabilizing selection, directional selection, and disruptive selection. In both cases, variation occurs but the variation rate is different. Therefore, the common thing between stabilizing selection and disruptive selection is variation. The variation rate is slow in stabilizing selection. Hence in this selection less phenotype characters are seen. In disruptive selection, variation is random and extreme. Thus more phenotype individuals are formed due to disruptive selection.
Answer:
The neuromuscular junction is a connection between a neuron and a muscle fiber.
Explanation:
The neuromuscular junction is formed by the connection between the axon terminal of a neuron and a muscle fiber. This union forms a bridge between the terminal button of a neuron and the muscle fiber membrane, through it the terminals of the neuron are connected with the motor terminal plates, just where the nerve impulses are received. This allows the contraction of muscle fiber, with acetylcholine being the neurotransmitter of muscle stimulation.
Answer:
Explanation:
nucleic acid is a polymeric macromolecule made up of repeated units of monomeric 'nucleotides' composed of a nitrogenous heterocyclic base which is either a purine or a pyrimidine, a pentose (five carbon) sugar (either ribose or 2′-deoxyribose), and one to three phosphate groups.
Answer:
When laws are made to protect a species, it is made to stop human interference. Often natural factors also are the reason for a species decline, some of these factors may include, habitat change, climate change and may also be a disease going through the species. In order to truly save a species you would have to isolate them in an area and make sure they are all healthy and the habitat does not change. The only issue with that is, they could lose some of their natural instincts such as hunting or being scared of humans. So a law may not be enough to save a species because there may also be many natural factors interfering with a species survival.
