Answer:

D). 8 kg mass

Explanation:

Acceleration of Falling Objects

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

The greater an object's mass, the greater its gravitational force. The earth has a strong attracting force for objects with smaller mass (including the moon), and the sun has an attracting force on the earth and other planets in our solar system. ... The stronger the pull of gravity on an object, the greater its weight.

Answer:

B

Explanation:

So lets go over facts of mieosis and mitosis:

Meiosis is sexual reproduction

Mitosis is asexual reproduction

Meiosis in animals is how they reproduce

Mitosis in animals is how they regenrate their cells

Mitosis copies the orgninal cell.

Meiosis mixes a male and female egg and sperm to form a zygote

Ok, knowing this. We can find our answer.

Since we know meiosis is sexual, and mitosis asexual, we can get rid of C.

We also know that meiosis is in animals, and so is mitosis, so we can get rid of A.

Finally we can get rid of D, since we know due to the male and female genetics(and through the swapping of chromesomes during prophase)that genetic variation occurs in meiosis, but since mitosis copies a single cell, it is not genetically varient.

<u>So the answer must be C, which states that Mitosis has genetically identical cells, while mieosis does not. </u>

Hope this helps! ;)

If you fill up a balloon with a small amount of air, then set it in direct sunlight, you will see that the balloon expands. This
lakkis [162]

Answer:

Increase in kinetic energy of the gases

Explanation:

The direct sunlight will heat up the molecules making up the gases in the balloon.

Kinetic energy resulting from the heating of these particles will make them become randomized. They then begin to move more haphazardly colliding vigorously with themselves and the wall of balloon.

According to Charles's law "the volume of a fixed mass of gas is directly proportional to its temperature provided pressure remains constant" .

The sunlight heats the balloon and causes a rise in temperature. This will make the gas volume to increase and the balloon expands.
