Different types of cells within an organism ______.

Natasha2012 [34]

The answer is C, serve a different function.

In multicellular organisms, same types of cells makes up a tissue, and tissue makes up organs, then eventually organs work together as an organ system.

For example in humans, stomach cells makes up the stomach tissues, and stomach tissues makes up the stomach. stomach can help digest food and mix food molecules together. But in opposition, red blood cells is present in the blood tissue, however, their function is not to digest food, but is to transport oxygen.

Therefore, we can see that different cells serve a different function.

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.

Alternative splicing of single mRNA transcripts gives rise to multiple mRNAs. View Available Hint(s) Alternative splicing of sin

Degger [83]

Answer:

<u>Option-</u> True

During the process of the protein synthesis the mRNA is processed through the stages of creating the multiple number of mRNA. As, these fragments help in the formation of the protein molecules or different amino acids sequences from the given set of 20 amino acids.

Biological nitrogen fixation (nitrogen fixation that is performed by living organisms) is carried out by ________.

nalin [4]

Bacteria
Nitrogen fixing bacteria are those that convert atmospheric nitrogen to different nitrogenous ions and add them to the soil. These bacteria may either be free living in the soil, or they may develop a mutualistic relationship with some organisms, such as the nitrogen fixing bacteria that live in the root nodules of leguminous plants. An example of a genus of nitrogen fixing bacteria is the genus Azotobacter.
