Answer:

The process by which chemicals are stored in the tissues of living organisms.

Explanation:

Bioaccumulation refers to the build up or accumulation of chemicals (organic and pesticides) inside of living organisms from all sources including- air, water and diet.

Bioaccumulation occurs when an organism takes in chemicals faster than they can degrade/excrete or use i.e. more is coming in than going out, or the organism cannot excrete or degrade the chemical at all, therefore, causing the chemical to accumulate in the organism, exposing the organism to risk of chronic poisoning. Hence, Bioaccumulation is the net result of all uptake and loss processes of chemical substances such as respiratory and dietary intake, egestion, excretion etc.

A vivid example of Bioaccumulation is the ingestion of mercury (a chemical contaminant) by fishes in water bodies. Phytoplankton and bacteria, which naturally feeds on mercury without it causing harm to them, is eaten by fishes, causing the mercury chemical to gradually accumulate in their system.

Bioaccumulation is the process by which chemicals are stored in the tissues of living organisms. It is the accumulation of chemicals in the tissue of organisms through any route including, respiration, ingestion or direct contact with contaminated water, sediment and pore water in the sediment. These chemical substances include, pesticides or other chemicals.

If the number of photosynthetic organisms on the earth decreased drastically, which would happen as a result?
IgorLugansk [536]
Photosynthetic organisms use the process of photosynthesis to produce their energy. During this process they also take in carbon dioxide and release oxygen. If there were less of such organisms, there would be more carbon dioxide  and less oxygen in the atmosphere.

What is the function of RBC
avanturin [10]

Answer:

When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.

The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.

There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.

Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water

Advantages to using a punnet square
timofeeve [1]
A Punnett square summarizes how the processes of meiosis and fertilization contribute to inheritance of different alleles of a gene. So one major advantage is it can help determine certain things about a child by looking at the dominant and recessive genes and gives a percent of how likely they are to get that thing for example a punnet square may show what color a child’s eye color is likely to be upon birth
