Sodium ions are more highly concentrated outside the cell, in the extracellular fluid. Which process would be used to return any
VashaNatasha [74]

Answer:

The correct answer is A. active transport

Explanation:

There are two types of transport which helps in the transport of molecules across the cell membrane. These are active transport and passive transport. In passive transport, the molecules move across the membrane without any energy expenditure and down their concentration gradient.

In active transport, molecules move against their concentration gradient with the help of ATP so in active transport, molecules can be present in high concentration outside or inside the cell.

Sodium is an ion that moves by active transport in and out of the cell with the help of sodium-potassium pump so it's so the correct answer is A.

Which form of natural selection does a graph repeat
Nookie1986 [14]
May i have choices but <span>Natural selection can take many forms. To make talking about this easier, we will consider the distribution of traits across a population in graphical form. In we see the normal bell curve of trait distribution. For example, if we were talking about height as a trait, we would see that without any selection pressure on this trait, the heights of individuals in a population would vary, with most individuals being of an average height and fewer being extremely short or extremely tall. However, when selection pressures act on a trait, this distribution can be altered.</span>

The melting of the polar ice caps and the direction of the wind passes through these states affecting or changing its weather. If humans keep doing this mother nature, humans will be left with a planet that's constantly changing and possibly inhabitable.

How does pollution threaten coral reefs? Answer using at least 3 complete sentences.
Lostsunrise [7]

Answer:

When pollution occurs on land it travels to the waters which causes the pollutants to enter the water. When pollution enters the water, it damages the algae on the coral. It also lowers water quality, smother the coral reefs, and it speeds the growth of the damaging algae. All these make the coral reefs more susceptible to disease which stops the reefs growth and reproduction.
