When two solvents are seperated by a semi premamble membrane, water flows

Water flows from the side of higher water potential (higher water concentration leads to higher water potential) to the side of lower water potential. 

This movement is called osmosis. Water potential means the tendency of water flowing away. The higher the water concentration the solvent/solution is, the higher the water potential is and the more likely it'll flow to the other side. 

Therefore, if one of the solvents has 10% water and the other has 50% water, water molecules will flow from the one with 50% water to the 10% one. This movement is completely natural and does not require extra energy. The net flow will stop until both sides have the same water concentration. Water still flows through both sides at that time, but no net flow. 

Note that osmosis is only the movement of water molecules, with the presence of semi-permeable membrane (which can decide what substances can go through), and the flow of down the water potential gradient. If any one of these is not applicable, the movement is not osmosis.

Which of the following is not common to both prokaryotic and eukaryotic cell division?
julsineya [31]

The correct answer is: A checkpoint will be activated if the spindle does not attach to a kinetochore.

Prokaryotes, do not undergo mitosis (like eukaryotes) and therefore have no need for a mitotic spindle. Prokaryotes also don’ t have checkpoints foor the regulation of cell division.

Normal eukaryotic cells (unlike cancer cells), move through the cell cycle in a regulated way in order to make sure that cells don't divide under conditions that are unfavorable for them. Information about their own internal state (nutrients, signal molecules, DNA integrity) is signal to go or not to go through the cell division. Because of that there are few checkpoints in the cell cycle at which the cell examines the signals and makes a “decision”. The major checkpoints are:

• The G1- the first point at which it must choose, once it passes the G1 checkpoint the cell enters S phase

• The G2-the cell checks DNA integrity and checks if replication is done well.

• The spindle checkpoint-at the transition from metaphase to anaphase.

This is the elliptical orbit of the Earth around the Sun. It takes 365.26 days to complete one orbit.
Strike441 [17]

Answer:

Complete orbit around the Sun takes about 365.26 days. The Earth’s rotation axis is tilted relative to the imaginary space orbit around the Sun.  This imaginary plane is called the ecliptic plane.  Position of northern and southern hemisphere toward the Sun varies depending on the season

algol [13]

a. hybridization

b. incomplete dominance

c. true-breeding

d. the law of segregation

e. polygenetics

Answer:

c. true-breeding

Explanation:

True-breeding is a type of breeding which involves a cross between two parents that are homozygous for a trait leading to the production of offspring from generation to generation that have genotypes that express the same phenotypic traits. The parent plants with purple flowers in the question, are both homozygous for flower color.
