YES.
The thirst mechanism always underestimates fluid loss during work, in the heat and after work ends. Therefore you should take frequent drinks through out the work period. If you drink 250mililitres every 15 minutes, you can replace one litre per hour. if sweat rate is higher you will find it extremely difficult to keep up with fluid needs. During prolonged periods of work in the heat, weight loss exceeds 2 percent therefore the person should rehydrate before returning to work.
Chemical reactions occur when chemical bonds between atoms are formed or broken. If this is what you mean because the question is really confusing sorry :(
Answer:
Diffusion
Explanation:
As substances like oxygen are non polar and are not dissolved in water they can diffuse through the cell membrane without the need of channel proteins whereas polar molecules would be repelled by the hydrophobic tails of the phospholipid bilayer an would need a channel protein

Answer:
External fertilization usually occurs in aquatic environments where both eggs and sperm are released into the water. After the sperm reaches the egg, fertilization can then take place.External fertilization is most common in amphibians and fish.
Explanation:
Some animals produce offspring through asexual reproduction while other animals produce offspring through sexual reproduction.
Sexual reproduction starts with the combination of a sperm and an egg in a process called fertilization. This can occur either outside the bodies or inside the female.There are two types of fertilization in sexual reproduction. Internal fertilization and external fertilization.External fertilization is a common and widespread in aquatic environments where both eggs and sperm are released into the water. After the sperm reaches the egg, fertilization takes place. Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time. The spawning may be triggered by environmental signals, such as water temperature or the length of daylight. Nearly all fish spawn, as do crustaceans (such as crabs and shrimp), mollusks (such as oysters), squid, and echinoderms (such as sea urchins and sea cucumbers). Frogs, corals, mayflies, and mosquitoes also spawn
