Answer:
In both cases, the person is deprived of ATP source as the aerobic cellular respiration comes to halt.
Explanation:
At higher altitudes, low oxygen pressure deprives the cells of oxygen to serves as the terminal electron acceptor. In the absence of molecular oxygen, electron transport from NADH and FADH2 to O2 can not generate the proton concentration gradient required for ATP synthesis.
Cyanide poisoning also stops ATP synthesis by inhibiting the electron transfer from cytochrome oxidase to oxygen. Cellular respiration is a source of ATP for living aerobic cells. In the absence of ATP synthesis, the person is deprived of energy sources and feels weakness, dizziness, confusion, and shortness of breath.
Answer:
Spawn is the eggs and sperm released or deposited into water by aquatic animals. As a verb, to spawn refers to the process of releasing the eggs and sperm, and the act of both sexes is called spawning.

Most fish reproduce by spawning, as do most other aquatic animals, including crustaceans such as crabs and shrimps, molluscs such as oysters and squid, echinoderms such as sea urchins and sea cucumbers, amphibians such as frogs and newts, aquatic insects such as mayflies and mosquitoes and corals, which are actually small aquatic animals—not plants. Fungi, such as mushrooms, are also said to "spawn" a white, fibrous matter that forms the matrix from which they grow

Answer: Timing of the cricket's chirps.
Explanation:
Answer:
When the calcium level is high in the bloodstream, the thyroid gland releases calcitonin. Calcitonin slows down the activity of the osteoclasts found in bone. This decreases blood calcium levels. When calcium levels decrease, this stimulates the parathyroid gland to release parathyroid hormone.
Answer:
1. car gets hot
2. Cars warm up in the sun due to the greenhouse effect: Sunlight passing through the windows into the car is mostly absorbed by interior surfaces, then radiated back to the air as heat. ... “As a consequence, the inside of the car will warm because radiation is coming in but not much is going back out.”
