The lateral hypothalamus signals an animal to start eating, whereas the <span>ventromedial </span>hypothalamus signals the animal to stop eating. So the correct option is the first one.
During bleeding, both formed elements (platelets, white blood cells, red blood cells) and plasma are lost from the circulatory system. They are lost proportionally, so initially there is no change in hematocrit.
Hematocrit is the percentage of the blood volume made up of elements (Hct = cell volume/blood volume). During dehydration, only water and electrolytes are lost, and the number of cells remains constant - the same number of cells in a smaller volume leads to an increase in hematocrit. When the body tries to restore blood volume, the first thing to recirculate is water from the ECF and this increases the amount of water without increasing the amount of red blood cells, so the compensatory mechanism causes the hematocrit to fall.

Answer: The virus weakens as time passes.
Explanation: The virus will weaken continuously during transmission, and will reduce its toxicity after several generations of transmission, without causing much harm to the human body.
Answer:
increase
Explanation:
The mevalonate pathway is known to generate isopentenyl pyrophosphate and dimethylallyl pyrophosphate, which are used to synthesize diverse compounds including cholesterol and steroid hormones. The levels of mevalonate in human plasma may be used as a measure of cholesterol synthesis. When the cholesterol level is low, it stimulates its endogenous production by the mevalonate pathway. Since it is well known that the vegetarian diet reduces cholesterol, this diet also increases mevalonate levels.
Streams or rivers form when water that does not find an underground aquifer, drains off the land by either seeping through the soil or spilling over the surface into the river or stream bed.
