Answer:
The correct answer is d.) they have a negative charge
Hydroxide ions, chemical formula OH⁻ are negatively charged anions.
Oxygen is covalently attached with hydrogen in hydroxide ion.
It is important as it can function as base, nucleophile, ligand as well as catalyst.
Chemicals containing hydroxide ions are considered as base. They dissociate in hydroxide ion and their respective cations in aqueous solution.
The Lewis dot structure of hydroxide ion is shown below.
The answer would be true.
Because the processes that produce defense against certain pathogens require lots of energy and resource, it is considered virtually a last resort, left for when they are threatened.
Hope I could help!
Explanation:
A missense mutation is when the change of a single base pair causes the substitution of a different amino acid in the resulting protein. This amino acid substitution may have no effect, or it may render the protein nonfunctional.
Answer:
I don't understand. do you have a picture or a file attached to it?
Answer: Option C.
if resistance increases, flow decreases.
Explanation:
if resistance increases, flow decreases describe Poiseuille's law because it explain the relationship between fluid flow and the viscosity of the fluid, length and width of the turning. The law describe fluid flow is related to length and radius of tubing and viscosity. Increase in resistance will result in decrease in flow rate because flow and resistance are reciprocally related in one way or the other.
