The ___________ theory suggests that mitochondria were once independent cells that were captured by another cell

Why do you think UV intensity changes with latitude?

Furkat [3]

Answer:

Because of the angle of the Earth relative to the sun. The higher the sun is in the sky, the higher the UV radiation level.

Explanation:

So, the lattitudes toward the poles that receive sunlight are at an oblique angle, with that being said, the amount of radiation is spread to a larger area than the equator.

Item 6 Over a 10-year period, a nation of 100 million people has a birth rate of 15 million, but a death rate of 5 million and a

likoan [24]

Decreasing first and then growing happening to the population because at every year 10.20 percent population is growing.

<h3>How can you figure out a population's growth rate when there are births and deaths?</h3>

The net reproduction rate (r) is computed as follows: r = (births-deaths)/population size, or simply multiply by 100 to get in percentage terms. Because the population has grown so much, many more people have been added. When a population grows at a steady rate year after year, this is referred to as exponential growth.

Migration is the the number of immigrants minus the number of emigrants over a given time period, divided by the number of person-years lived by the receiving country's population during that time period. It is calculated as the number of net migrants per 1,000 people.

If a swimmer cuts his foot on a seashell while wading in the ocean and bleeds into the seawater, his erythrocytes will shrink. W

Effectus [21]

Answer:A) The ocean is hypertonic to the erythrocytes.

Explanation:cells shrink when placed in an hypertonic solution.

This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.

The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.

In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell
