A/An solution occurs when the solute concentration outside of the cell is higher than the solute concentration inside the cell

Most cells have an electrical potential difference of between –40 and millivolts.

is a determining force in water movement, and causes water to move from areas of high water concentration to low water concentration.

In most cells, there are more molecules inside the cell and more sodium molecules outside the cell.

A/An exists when different concentrations of a substance exist on either side of a membrane.

Describe the difference between a chemical and an electrical gradient.

What's an electrochemical gradient?

Do you think an electrochemical gradient can have conflicting component gradients? (That is, a chemical gradient directing solute flow in one direction, and an electrical gradient directing solute flow in the opposing direction.)

answer; i believe the correct answer is (replication is not conservative);

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

explanation:

the correct answer is option d.

an appositive is a noun, noun phrase or noun clause which follows another noun or noun phrase in order to describe it or name it another way. they are usually used between commas, brackets or dashes.

the example sentence with the correct use of commas is the following:

her uncle, the man over there in the red shirt, owns the hardware store in town.

segmented body, an exoskeleton made from chitin, and joint appendages.
