Q: What is the outer layer of the adrenal gland called? Read this paragraph and choose the correct option from the provided answers: 17.6 The Adrenal Glands The adrenal glands, located superior to each kidney, consist of two regions: the adrenal cortex and adrenal medulla. The adrenal cortexthe outer layer of the glandproduces mineralocorticoids, glucocorticoids, and androgens. The adrenal medulla at the core of the gland produces epinephrine and norepinephrine. The adrenal glands mediate a short-term stress response and a long-term stress response. A perceived threat results in the secretion of epinephrine and norepinephrine from the adrenal medulla, which mediate the fight-or-flight response. The long-term stress response is mediated by the secretion of CRH from the hypothalamus, which triggers ACTH, which in turn stimulates the secretion of corticosteroids from the adrenal cortex. The mineralocorticoids, chiefly aldosterone, cause sodium and fluid retention, which increases blood volume and blood pressure. Choices: - adrenal skin - zona reticularis - medulla - adrenal cortex A:
adrenal cortex

Q: What helps pumice float in water? Read this paragraph and choose the correct option from the provided answers: Some extrusive igneous rocks cool so rapidly that crystals do not develop at all. These form a glass, such as obsidian. Others, such as pumice, contain holes where gas bubbles were trapped in the lava. The holes make pumice so light that it actually floats in water. The most common extrusive igneous rock is basalt. It is the rock that makes up the ocean floor. Shown below are three types of extrusive igneous rocks ( Figure below ). Choices: - high density - large mass - gravity - gas bubble holes A:
gas bubble holes

Q: What are the 2 primary hosts of ebola in central africa? Read this paragraph and choose the correct option from the provided answers: Several lethal viruses that cause viral hemorrhagic fever have been discovered, two of which are shown in the Figure below . Ebola outbreaks have been limited mainly to remote areas of the world. However, they have gained extensive media attention because of the high mortality rate23 percent to 90 percentdepending on the strain. The primary hosts of the viruses are thought to be apes in west central Africa, but the virus has also been isolated from bats in the same region. Choices: - hyenas and apes - apes and hippos - lions and elephants - apes and bats A:
apes and bats
