Answer with Explanation:
"Biome" refers to the flora (plant life) and fauna (animal life) of a particular place. It also includes the climate and specific conditions that allow the living organisms in the environment to survive.
The biome of North Africa consists of both desert biome and rainforest biome. It can be classified into a "savannah biome." This means that both the grassland and the woodland co-exist with each other. On the contrary, the biome in Iceland consists of a "tundra biome." The appearance of this biome is uniform and it is considered the coldest among all the other biomes.
Both of the biomes in North Africa and Iceland are different owing to their temperature, precipitation, nutrients from the soil and so on. The savannah biome consists of both wet and dry climates. These seasons allow the growth of both trees and grasslands. When it comes to the tundra biome, its temperature is extremely low. Thus, it doesn't allow many plants or trees to grow. However, it allows the growth of some unique types of wildlife such as the "Arctic fox."

Explanation:
Sodium (Na) and Chlorine (Cl) are two electrolytes that play important role in the absorption of water and nutrients in the small intestine. However, as mentioned in the question, the release of sodium and chlorine would lead to a loss of water in the intestines. This is because of the OSMOTIC phenomenon.
Osmosis is the movement of water molecules from a region of high concentration of water/low concentration of solute to a region of low concentration of water/high concentration of solute via a semipermeable membrane. In this case, the Na+ and Cl- ions serve as the solutes, which when released out of the intestine causes the solution in the intestines to be HYPOTONIC compared to the intestinal environment. This causes an OSMOTIC GRADIENT.
This osmotic gradient i.e. difference in concentration provokes osmotic flow of water from the intestines, which has a low solute/high water concentration, to the outside of the intestines, which has a high solute/low water concentration. Hence, water is lost from the intestine because the solute concentration becomes low when sodium and chlorine ions are released.
Answer:
yes because fruits need to be pollinated in order to blossom out of being a flower
Answer: Blood sugar/blood glucose levels are controlled by negative feedback involving the hormones human insulin and glucagon.
Explanation:
Insulin is produced in the increased , if there is too little glucose in the blood the pancreas is triggered and released more insulin to change glucagon into glucose, this regulates the amount of glucose in the blood. However if there is too much glucose in the blood (after a sugary meal) the pancreas is triggered to use insulin to lower the blood glucose levels, this is called negative feedback. This works by storing glucose as glucagon in the blood, insulin can be objected into the blood stream if a person needs it straight away(eg type 1 diabetes.)

True north is a fixed point on the globe. Magnetic north is quite different. Magnetic north is the direction that a compass needle points to as it aligns with the Earth's magnetic field. ... However, its position is constantly changing, and soon magnetic north and true north will align.
