Well, the food is in the environment. I would like to compare it with how bacteriae feed (however my biology is quite rusty), that is, they engulf their food and they "digest" -- not the proper term, since there are no organs to do real digestion -- it.

A bond of the following elements would be of what type? Na + Cl <br><br> Covalent or ionic
nikklg [1K]

Answer:

ionic

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.

There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.

2Na + Cl₂ → 2NaCl

¿Cuál es la importancia de la fusión nuclear? What is the importance of nuclear fusion?
Rama09 [41]

Without it, there are no stars, including our own sun, and there wouldn’t be us talking about it.

It is used in particularly destructive bombs.

At a tiny scale, it can be used to produce neutrons, eg, a Farnsworth Fusor.

At a large scale, we have yet to figure out how to make controlled fusion work in a way that runs for a long time and generates collectible power we can use to feed the process. This has remained elusively 20 years out from the current state of affairs for 50 years.

If it was made to work, then it would probably be a good source of clean energy that would be safer than many of the non-renewable alternatives.

I don’t expect to live to see it happen.

Why is the plasma membrane selective
rjkz [21]
The plasma membrane is selective because it has to be able to determine what is vital to the body or what is dangerous and unable to be received. Specifically the plasma membrane is a part of the cell that is contained of lipids and proteins. It is the regulation center of the cell and it's operation is functional to a living organism.
