This statement is true. Cells are able to regulate what they do or do
not need in order to maintain their own health - this is done through
the particular things that are filtered or not filtered through the cell
membrane.
D. Mercury, Mars, Jupiter, Saturn. Mercury is the planet with the fastest orbital speed in our solar system, Mars is the fourth, Jupiter is the fifth, and Saturn is the sixth.
Glad to help!
<h2>Answer 1:</h2>
The gravitational force is a force that attracts any objects with mass. Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy including planets, stars, galaxies, and even light are brought toward one another.
Answer 2:
Gravity keeps things together. It is a force that attracts matter towards it. Anything with mass creates gravity, but the amount of gravity is proportional to the amount of mass.
Gravitational force is critical to our universe because with out gravitational force we cannot walk on earth, all the matter on earth cannot stay on it with out gravity. Everything will start floating in air with out gravity.
<h2>Answer 3:</h2>
Gravity is the powerful force that glues our universe together.
- One of the most noticeable effects of gravity in the solar system is the orbit of the planets.
- The planet keeps moving but is always caught up in the push-pull forces caused by the interaction of these gravitational forces. As a result, the planet begins orbiting the sun.
- The same phenomenon causes the moon to orbit around the Earth except its the Earth's gravitational force not the sun's that keeps it moving around us.
