Answer:
Hawaii islands are not formed at tectonic boundaries, but rather at a hotspot. This is a place where hot magma, from deep in the mantle rises to the surface, and through the crust, as the Pacific tectonic plate moves towards the northwest. This magma is very hot because it rises directly from the bottom layers that are hotter than upper mantle. This hotspot is at the boundary of two convection currents in the mantle. The hotspot’s magma pierces through the crust and erupts into a volcanic mountain. The hotspot is more or less stagnant, but in comparison, the tectonic plate above it is moving. Therefore, over time, there will a chain of the mountain as the plate moves over the hotspot.
Answer:
The term "disease" refers to conditions that impair normal tissue function. For example, cystic fibrosis, atherosclerosis, and measles are all considered diseases. However, there are fundamentally different causes for each of these diseases. Cystic fibrosis (CF) is due to a specific genotype that results in impaired transport of chloride ions across cell membranes, leading to the production of abnormally thick mucus. Thus, CF is most accurately called a genetic or metabolic disease. Atherosclerosis, which can lead to heart attacks and strokes, may be considered a disease of aging, because it typically becomes a problem later in life after plaques of cholesterol have built up and partially blocked arteries. In contrast, measles is an infectious disease because it occurs when an individual contracts an outside agent, the measles virus. An infectious disease is a disease that is caused by the invasion of a host by agents whose activities harm the host's tissues (that is, they cause disease) and can be transmitted to other individuals (that is, they are infectious).
Explanation:
Answer:
The answer is B.
Explanation:
Acetoacetate and Acetyl CoA share a precursor with cholesterol synthesis which begins with Acetyl Coa but not β‑hydroxybutyrate.
Modifying other enzymes can be said for β‑hydroxybutyrate but not Acetoacetate.
They are not both produces from Acetyl Coa of fats. β‑hydroxybutyrate is produces from the acids with fats in the liver but the same can not be said for Acetoacetate.
However they both can be said to provide energy for the brain because they are both released into the bloodstream in the event of hunger or when the body/brain needs energy in a state of fasting.
I hope this answer helps.
