Was the membrane at a stable equilibrium before you pushed it? How could you tell?

Answer:

Well, first let's define the difference between stable and unstable equilibrium.

Stable: After a little perturbation, the equilibrium state is retaken.

Unstable: After a little perturbation, the state changes to one more stable.

An example of this is:

Imagine a pencil, when the pencil lays down in the table, it is in stable equilibrium because you can touch it and it will return to the same initial state.

Now suppose that the pencil is standing up (we can think this as a more energetic state). The pencil is in equilibrium, it does not move and there is no force acting on it.

Now you can touch it (a small perturbation) and the pencil will likely fall down, to the stable state of equilibrium.

That is the difference between stable and unstable (There is also an image below, where you can see it in a more physical way, where the vertical axis represents energy and the horizontal represents a given variable or set of variables).

Then, how to know if the membrane was at a stable equilibrium before you pushed it?

Did it return to the initial state? then yes, it was a stable equilibrium

Did It change to a less energetic state? Then no, it was in an unstable equilibrium.

Answer:

Sulfur; nitrogen.

Explanation:

Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.

This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.

Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.

Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.

Select all of the true statements regarding non‑shivering thermogenesis.
lora16 [44]

Answer:

a, b, d y e

Explanation:

We can define thermogenesis as the method of production of lime or temperature that a living body generates, in biology it is studied that this does not occur in all animals, but is seen in so-called warm blood and some plants, there are three types of processes identified in animals:

NEAT: defined as thermogenesis that occurs without the presence of physical activity

DIT: defined as the thermogenesis that occurs with physical activity

EAT: defined as the thermogenesis that occurs with the consumption of food or diet

Thermogenesis under the thermogenin protein found in brown adipose tissue produces a disengagement of protons within the mitochondria, prevents ATP synthesis and is capable of inducing temperature with the flow of protons, it also intervenes by increasing glycolysis, lipogenesis and gluconeogenesis with which its final result in these processes is the production of energy. The effect of the sympathetic nervous system and thyroid hormones that can balance heat production without generating abnormal movements such as tremor is also recognized.

Thus we deduce that:

electron transport allows heat flow without causing tremors

Thermogenin is involved in allowing protons to enter the mitochondria and the ATP production process is carried out.

hydrolysis of fatty acids occurs in the presence of norepinephrine

in brown adipocytes ATP synthase can be avoided
