The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. In population biology, carrying capacity is defined as the environment's maximal load, which is different from the concept of population equilibrium. Its effect on population dynamics may be approximated in a logistic model, although this simplification ignores the possibility of overshoot which real systems may exhibit.

Carrying capacity was originally used to determine the number of animals that could graze on a segment of land without destroying it. Later, the idea was expanded to more complex populations, like humans. For the human population, more complex variables such as sanitation and medical care are sometimes considered as part of the necessary establishment. As population density increases, birth rate often increases and death rate typically decreases. The difference between the birth rate and the death rate is the "natural increase". The carrying capacity could support a positive natural increase or could require a negative natural increase. Thus, the carrying capacity is the number of individuals an environment can support without significant negative impacts to the given organism and its environment. Below carrying capacity, populations typically increase, while above, they typically decrease. A factor that keeps population size at equilibrium is known as a regulating factor. Population size decreases above carrying capacity due to a range of factors depending on the species concerned, but can include insufficient space, food supply, or sunlight. The carrying capacity of an environment may vary for different species and may change over time due to a variety of factors including: food availability, water supply, environmental conditions and living space. The origins of the term "carrying capacity" are uncertain, with researchers variously stating that it was used "in the context of international shipping" or that it was first used during 19th-century laboratory experiments with micro-organisms. A recent review finds the first use of the term in an 1845 report by the US Secretary of State to the US Senate.

Hi there!
There is a way that the human body cools itself, but it sounds so weird!
Did you know that when you sweat after doing something constantly, the sweat tries to cool the body down? It's true!
I learned this is physical science class, and we tested it for ourselves. We ran around a bunch of times around my old school and then we started sweating. Not too long afterwards, we started cooling down because of the sweat.
Weird, right?
Hope this helps!
Message me if you need anything else! :D
Answer:
The answer is D
Explanation:
I just took the test
Protein synthesis is an anabolic reaction because these reactions build molecules while catabolic ones break them down. Thanks to this we know that protein synthesis is anabolic.
Explanation:
Anabolism relates to the process in cells where large macromolecules are formed up from miniature ones. In this case here, protein structure uses other proteins and amino acids (proteins' monomers) to make extra proteins, and so that is the accumulation of a large molecule, and accordingly studied anabolism.
Catabolism is the reverse of anabolism. An example would be the separation of proteins in food to amino acids for digestion. In this case, a large particle (a protein) is split down into miniature dispersible molecules (amino acids).
