Answer:

The plant that should be moved to not become malnourished is the plant 3.

Explanation:

The visible spectrum, or optical spectrum, is the portion of the electromagnetic spectrum whose radiation is composed of photons capable of sensitizing the human eye of a normal person. The corresponding range of visible light radiation is identified.

With that being said, plant 3 is in front of a green stained glass. plants have chlorophyll pigment that reflect back the green light, so the green light is least effective for photosynthesis and for that reason it will die as quickly as if it is kept in dark.

Why don’t we have a complete fossil record of all life that’s ever lived?

Ivanshal [37]

Answer:

Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions. Fossils must be exposed at Earth's surface to have a chance of being found. Fossils can be destroyed when rocks erode, melt, or change composition.

Explanation:

For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.

Irina18 [472]

A CNA, certified nursing assistant, can administer medication to patients. BUT this duty is subject to the level of experience and training of the CNA as well as the regulation of the state.

CNAs basically assist in the day-to-day care of patients like:
1) bathe and dressing
2) serving meals and helping them eat
3) taking their vital signs
4) and other basic necessities to ensure that the patient is comfortable and well cared for.

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

liq [111]

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.
