The correct answer is - C. -1.9 C degrees.

The sea ice in the polar oceans needs little lower temperatures to start forming than what it would need if it was't forming on a saline water. The freshwater starts freezing as the temperature goes bellow 0 C degrees, but that is not the case with the saline water. The saline water, because of the salt that prevents the freezing to a certain point, needs temperature of -1.9 C degrees to start freezing. Once this temperature is reached, the salt can not prevent the freezing anymore, so the water on the polar oceans starts to freeze.

Explanation:

Flowering plants also called Angiosperms are a group of plants characterized by the possession of flowers used for sexual reproduction. The flowers contains the male part and female part.

The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. this would result in
xxMikexx [17]

Answer:

The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.

Explanation:

The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.

Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.

During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.
