Q: The subducting oceanic plate does what as it reenters the mantle? Read this paragraph and choose the correct option from the provided answers: As you would expect, where plates collide there are lots of intense earthquakes and volcanic eruptions. The subducting oceanic plate melts as it reenters the mantle. The magma rises and erupts. This creates a volcanic mountain range near the coast of the continent. This range is called a continental arc . The Andes Mountains, along the western edge of South America, are a volcanic arc ( Figure below ). Choices: - evaporates - disappers - freezes - melts A:
(A).
melts

(Q).
Q: The hormones epinephrine and norepinephrine are released by what? Read this paragraph and choose the correct option from the provided answers: Short-term Stress Response When presented with a stressful situation, the body responds by calling for the release of hormones that provide a burst of energy. The hormones epinephrine (also known as adrenaline) and norepinephrine (also known as noradrenaline) are released by the adrenal medulla. How do these hormones provide a burst of energy? Epinephrine and norepinephrine increase blood glucose levels by stimulating the liver and skeletal muscles to break down glycogen and by stimulating glucose release by liver cells. Additionally, these hormones increase oxygen availability to cells by increasing the heart rate and dilating the bronchioles. The hormones also prioritize body function by increasing blood supply to essential organs such as the heart, brain, and skeletal muscles, while restricting blood flow to organs not in immediate need, such as the skin, digestive system, and kidneys. Epinephrine and norepinephrine are collectively called catecholamines. Choices: - uptake medulla - nutrients medulla - external medulla - adrenal medulla A:
(A).
adrenal medulla

(Q).
Q: Pieces of the cell break off and form a new cell in what type of reproduction that produces genetically identical organisms? Read this paragraph and choose the correct option from the provided answers: Like bacteria, reproduction in archaea is asexual. Archaea can reproduce through binary fission , where a parent cell divides into two genetically identical daughter cells. Archaea can also reproduce asexually through budding and fragmentation, where pieces of the cell break off and form a new cell, also producing genetically identical organisms. Choices: - Meiosis - Mitosis - Fusion - fragmentation A:
(A).
fragmentation
