Give one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process.

NeTakaya

Answer:

Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism).

Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions.

In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.

A.) Water would either cool down or warm up, depending on the temperature. That would also alter the air and its heat as the water evaporates.

B.) (same as first)

Simply edit your answer based on temp. Hope this helps!

Science rejects any hypothesis not supported by __________________________ and the results of ___________________________ experi

Ket [755]

Answer:

Observations; control.

Explanation:

A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.

On the other hand, a control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.

Hence, science rejects any hypothesis not supported by observations and the results of control experiments.

This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.

This sample is naturally occurring, inorganic, solid, has a square crystal structure, and a definite chemical composition (NaCl)

Alika [10]

Answer:

A Mineral is defined as an inorganic, naturally occurring, homogenoussolid, with a definite chemical composition, and ordered (crystalline) atomic structures.

Explanation:

Inorganic: Involving neither organic life nor the products created from or by organic life.

Naturally Occurring: Must be formed by natural processes, meaning a mineral cannot be manmade, manufactured, or created in a laboratory.

Homogeneous Solid: A mineral must be chemically and physically uniform down to the atomic level.

This homogeneity means that the mineral will have absolutely predictable physical properties

including hardness, density, and streak.

Definite Chemical Composition means that all occurrences of that mineral have a chemical

composition that varies within a specific limited range and the atoms that make up the mineral must

occur in specific ratios.

Ordered Atomic structure (Crystalline): The atoms in a mineral are arranged in a systematic and

repeating pattern. Glasses such as obsidian, which are disordered solids, liquids (e.g., water,

mercury), and gases (e.g., air) do not have a crystalline structure and are therefore not minerals.
