Answer:
Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. The membrane also maintains the cell potential.
Explanation:
(see above)
I do not know if this is the correct answer,
Ionic Bonds - Whichever two atoms give one electron to the other
Covalent Bond - Is whenever two atoms share electrons and they go back and forth between the two
I do not know what the third type is you would have to comment and let me know and I will try to find it for you! :)
The answer is; acetyl-CoA
This organic compound is an intermediate of the TCA/Citric/Krebs cycle. To make fats, the coenzyme is carboxylated to manolyCoA. This becomes a precursor fo palmitate and other lipids in the body by the addition of more manolyCoA.
The coenzyme is also a precursor to the formation of alpha-ketoglutarate, another intermediate of the TCA cycle, which is also a precursor in the formation of proteins.
Answer:
e.iv, iii, i, ii
Explanation:
Be has electron configuration of 1s^2 2s^2. During bond formation, one 2s electron is promoted to a 2p orbital. Hence two hybrid sp beryllium orbitals are formed. These two hybrid orbitals are used in sigma bond formation to fluorine atoms.
Recall that fluorine has filled 2p orbitals containing lone pairs of electrons. These filled orbitals can interact with the unhybridized 2p-orbitals on beryllium to form pi bonds. This is the reason for the sequence of events chosen in the answer.
Answer:
Properties of Metals:
- Shiny
-Malleable
-Good Conductors of electric current
- Good conductors of heat
Properties of Non-metals:
- Dull
- Not Malleable
- Bad conductors of electric current but good electric insulators
- Poor conductors of heat
Note: The first dash for the Properties of metals goes with the first dash of Properties of Non-metals and so on.
