Answer:
Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).
Examples of where diffusion is important;
In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.
Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.
Answer:
four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts.
a air front is a weather system that is the boundary separating two different types of air. One type of air is usually denser than the other, with different temperatures and different levels of humidity.
A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. ... Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.
Stationary Front - a front between warm and cold air masses that is moving very slowly or not at all.
Occluded Front - a composite of two fronts, formed as a cold front overtakes a warm

Answer:
In all different levels of the food webs and food chains, it is seen that damaged members of the prey have become easy food for the predators.
Explanation:
Preys can identify the other members of their species are injured or wounded or fed by the predators by their body fluid in as if a predator eats the prey the blood or other body fluid releases. These fluids or blood help individual prey species to be aware of the predator as they recognize that their species member is wounded or consumed by there olfactory receptors.
There are several other chemicals cue that is species specif that are released by the prey to alarm the other species member by injured or dead members.
Thus, the correct answer is - In all different levels of the food webs and food chains it is seen that damaged members of the prey have become easy food for the predators.
