B because cactus' are usually in a dry environment, they close their stomata during the day to keep water vapor from leaving the plant. Instead they do their processes at night to avoid extreme water loss.
Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
Hope this helps your question.
The answer is D, the larynx lifts
The pituitary gland, or hypophysis, is an <span>endocrine gland that consists of anterior pituitary (or adenohypophysis) and posterior pituitary (or neurohypophysis). Adenohypophysis regulates several physiological processes (including stress, growth, reproduction, and lactation) by secreting hormones. The neurohypophysis functionally connects the gland to the </span>hypothalamus. The intermediate lobe (between adeno and neurohypophysis) synthesizes and secretes melanocyte-stimulating hormone. Because it controls a lot of functions inside the organism it can affect many things when it is not working properly (over- or under-production of pituitary hormones). It can cause diabetes insipidus by a deficiency of vasopressin, it can cause thyroid disorders, gigantism (too much growth hormone)…
Answer:
oligodendrocytes
Explanation:
Glial cells are part of the nervous system. These are helper cells that support the function of the central nervous system (CNS) and can be called oligodendrocytes when they supply myelin to neurons. These cells are responsible for producing the myelin sheath have the function of electrical insulator for CNS neurons. They have extensions that wrap around the axons, producing the myelin sheath.
It is estimated that there are 10 glia cells in the CNS for each neuron, but because of their small size, they occupy half the volume of nervous tissue. They differ in form and function and they are: oligodendrocytes, astrocytes, Schwann cells, ependymal cells, and microglia.
