the image here is a spiny stickleback, with the three spines highlighted with black arrows. The spines are a rigid projection of

the external scales. The three-spine stickleback is found in freshwater lakes, but it is rarely found in oceans. Large oceans have spineless sticklebacks that lack these projections. Which component of natural selection is likely driving the change in phenotype distribution of these two sticklebacks in different environments?

The component of natural selection which is most likely driving the change in phenotype distribution is, that the presence of spines on stickleback caused increased food acquisition and survival in ocean areas.

<h3>What do you mean by Natural selection?</h3>

Natural selection may be defined as a process through which populations of living organisms adapt and change. It involves the favorable variations to carry forward.

Stickleback play a major role in the diet of fish. This structure of fish allows them to feed on small crustaceans and insects.

Therefore, it is well described above.

In the formula, E K = 1/2 • m • v 2 if mass (m) was doubled, how much would kinetic energy
Viktor [21]

Answer:

mass doubled makes KE twice as large

velocity doubled makes KE 4 times as large

Explanation:

Try it with an example

m = 4

v = 8

KE = 1/2 m * v^2

KE = 1/2*4 * 8^2

KE = 1/2 * 4 * 64

KE = 128

Now double the mass

m  = 8

v = 8

KE = 1/2 8 * 8^2

KE = 1/2 8 * 64

KE = 4 * 64

KE = 256 double what it started out as.

Now do it again.

m = 4     That was the original mass

v = 16

KE = 1/2 4 * 16^2

KE = 2 * 256

KE = 512

When the velocity is doubled the KE becomes 4 times as big.

4*128 = 512

trapecia [35]

Answer:

Your answer is B.

Explanation:

Since elements can't exactly "die", the element rather breaks down in the soil below it, and is used again upon the next plant or animal.

Hope I helped :)

A mountain climber at the peak of a mountain has what type of energy?
zubka84 [21]
A climber at altitude has potential energy due to efforts to lift him higher in gravity's grip. His elevation gives him the potential to create kinetic energy if he had the misfortune to fall off

In the lumen of the proximal tubule, Na concentration is ________ the Na concentration inside the cells of the tubule wall.
nydimaria [60]

Answer:

The correct answer is - higher than

Explanation:

In the lumen of the proximal tubule of the kidney, most of the solutes are absorbed in the form of sodium. There is a gradient of sodium ions which allows the absorption of the solutes from the lumen into the cell.

It is due to the solute or  Na concentration is higher in the lumen than Na concentration inside the cells of the tubule wall. So movement of the solutes is due to the concentration gradient.
