Which graph represents selection that may lead to reduced variation in a population? A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population and population after selection have similar curves, but the original population peaks before the population after selection. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The population after selection increases, decreases, increases, and then decreases again. The original population increases at the point that the original population drops. A graph has trait value on the horizontal axis and population of individuals on the vertical axis. The original population peaks at the same time as the population after selection but the population after selection peaks higher and at a more rapid speed.

Answer:

Explanation:

The second student set up solutions that were in equilibrium.

On which principle Dialysis is based?

Dialysis is based on the principles of osmosis, meaning the net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration. If the solute concentrations are the same on each side of the membrane, this spontaneous movement will not occur.

In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing  molecules of water to diffuse across the membrane along the concentration gradient.

Therefore, the second student set up solutions that were in equilibrium.

QUICK ASAP PLS Certain bacteria live and grow on the roots of some plants and produce chemicals that are beneficial to the plants. Which of the following observations best supports the claim that this relationship is beneficial to the plants?



Group of answer choices

Plants with a higher amount of the bacteria on their roots have increased rates of survival and reproduction.

When the bacteria are removed from the plant roots and are grown in a laboratory setting, they fail to survive.

The population size of the bacteria varies greatly depending on the chemistry of the soil and the type of the plant.

The chemical produced by the bacteria can be created by humans and added to the soil where it reaches the roots of the plant.

Why is water called the universal solvent?
A.) Water is a nonpolar substance that dissolves polar substances
B.) Water can act as a solvent in many different solutions
C.) Water is a polar substance that dissolves nonpolar substances
D.) Water can act as a solute in many different solutions

Answers

Answer:

And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... This allows the water molecule to become attracted to many other different types of molecules.

Explanation:

B.) Water can act as a solvent in many different solutions.

Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.A water molecule consists of two hydrogen atoms and one oxygen atom. The three atoms make an angle; the H-O-H angle is approximately 104.5 degrees.

Therefore, option B. is correct.
