Answer:

Transport proteins (carrier proteins and channel proteins) allow substances into and out of the cell that cannot pass through the phospholipid bilayer (as they’re either to large, charged or not lipid soluble) by facilitated diffusion.

Specifically channel proteins allow ions into and out of the cell by creating a pore in the membrane in which they can move through with their concentration gradient

lana [24]

Answer;

-Communities that experience moderate disturbances often exhibit greater species diversity than other communities,

-Moderate disturbances create openings/opportunities for colonizing species

Explanation;

-Ecological disturbances may be generated by abiotic, or nonliving, forces such as weather and wildfires, or they may occur as a result of biotic, or living, forces such as disease and invasions of exotic species.

-Disturbance can result from natural causes or from the activities of humans. Disturbance can be caused by physical stressors such as volcanic eruptions, hurricanes, tornadoes, earthquakes, and over geological time, glacial advance, and retreat.

-Humans can also cause physical disturbances, for example, through construction activities. Wildfire is a type of chemical disturbance caused by the rapid combustion of much of the biomass of an ecosystem and often causing mortality of the dominant species of the community such as trees in the case of a forest fire.

The anterior and posterior lobes of the pituitary differ in that _____.
sleet_krkn [62]

Answer:

many anterior pituitary hormones regulate other endocrine glands whereas posterior pituitary hormones regulate nonendocrine tissues

Explanation:

Anterior pituitary or adenohypophysis is the anterior lobe of the pituitary gland. Secretion of endocrine cells of the anterior pituitary is controlled by regulatory hormones released by hypothalamus. The hypothalamic releasing hormones bind to anterior pituitary endocrine cells, upregulating or downregulating their release of hormones. Anterior pituitary hormones stimulate endocrine glands: FSH and LH (ovaries and testes), TSH (thyroid), and ACTH (adrenal cortex).

Posterior pituitary or neurohypophysis is the posterior lobe of the pituitary gland. It  is not glandular it is just a collection of axonal projections from the hypothalamus. Posterior pituitary hormones regulate nonendocrine tissues: ADH-vasopressin (kidney tubules) and oxytocin (mammary glands, uterine tissues, brain).
