Maintain population numbers close to the habitat carrying capacity are called _______ species
Animal species that exhibit long gestation periods, give birth to relatively large offspring, and maintain population numbers close to the habitat carrying capacity are called K-selected species.
In nature, a given habitat contains sufficient resources such as food, water, etc. to support a maximum possible number of biological species, beyond which no further growth is possible. It is termed as nature's carrying capacity for that species in the habitat.
MacArthur and Wilson proposed that there are two life-history strategies i.e. K-selected and r-selected. K-selected species exhibit a proportionately stable population that gives rise to a low number of offspring which tend to be very large. For example the African elephant is included among K-selected species.

What are the 4 ways or mechanisms by which a planet or moon can gain an atmosphere?
Four processes—outgassing, evaporation, sublimation, and surface ejection—can help a planet or moon to gain an atmosphere.
1) Outgassing: The release of a gas that has been dissolved, trapped, frozen, or absorbed in a substance is known as outgassing.
The outgassing that took place as the smaller, inner planets cooled down is likely how they acquired their atmospheres (volcanoes).
2) Evaporation : The process of converting anything from a liquid or solid state to vapors is called evaporation (like fog, mist, or steam).
So upon evaporation, water converts into gas and that's how moon gain an atmosphere by evaporation.
3) Sublimation : Converting a solid directly into a gas without first going through a liquid phase.
4)Surface ejection: A surface ejection is a massive discharge of plasma and magnetic field into the heliosphere from the Sun's corona.

What hormone helps to maintain extracellular fluid (ecf) osmolality when concentrations become too high?
Vasopressin, also known as Antidiuretic hormone (ADH) helps to maintain extracellular fluid (ECF) osmolality when concentrations become too high.
When osmolality increases, it stimulates the body to produce Antidiuretic hormone (ADH). This hormone instructs the kidneys to retain more water inside the blood vessels as a result, the urine becomes more concentrated.
Osmolality refers to the concentration of dissolved particles of chemicals and minerals like sodium and other electrolytes in the serum. Osmolality increases when the body is dehydrated whereas, it decreases when too much fluid in present in the blood.
Antidiuretic hormone (ADH) or Vasopressin checks the amount of water reabsorbed from the nephrons. This regulates the water content of the blood which is termed as osmoregulation.

Plasma proteins decrease in a person with liver failure. what effect does this have on capillary filtration/absorption?
The most significant factor contributing to widespread edema brought on by decreased plasma protein production in chronic liver disease is hypoalbuminemia, which manifests in end-stage liver disease. It leads to the increase on capillary filtration/absorption .
The osmotic pressure in blood arteries is maintained in large part by plasma proteins, which are also crucial carriers of several chemicals, including hormones. Blood pressure is the main factor influencing Glomerular filtration rate (GFR), which is countered by Bowman's capsule fluid pressure and colloid osmotic pressure brought on by plasma proteins.
The plasma has a lower than usual colloid osmotic pressure because there are less plasma proteins present. GFR rises when there is less colloid osmotic pressure working against it.
