Botonomy is the study of plants
<span>A single tree absorbs tons of carbon dioxide in its 30-year life cycle and it releases a ton of oxygen. The free nitrogen from the atmosphere is captured by the nitrogen-fixing bacteria and it converts nitrogen into nitrates and nitrites which is then absorbed by the plants. Trees, like all organisms, grow by adding mass (biomass). Carbon is the central ingredient in making that new biomass. Tree biomass is comprised of all parts of the tree; leaves, stems, branches, roots, tree trunks. The biomass of the woody tissue in the tree pictured on the right is made mostly of cellulose, a carbon compound. In a process called carbon fixation, plants transform CO2, an inorganic carbon compound into organic carbon compounds.</span>
I think the correct answer from the choices listed above is the last option. It is the hormone oxytocin that is controlled by a positive-feedback mechanism. Oxytocin is normally produced by the paraventricular nucleus of the hypothalamus and released by the posterior pituitary.<span> Hope this answers the question.</span>
Answer:
Disruptive selection
Explanation:
Disruptive selection, also known as diversifying selection, describes changes in population genetics where extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. In this more individuals acquire peripheral character value at both ends of the distribution curve.
