Answers

Answer:

Actually, Sherman, there are more black moths than white ones because of natural selection. The black moths blend into the environment, while the white moths do not. This means that the predators of the moths will find and eat more white moths than black moths. Then, this leads to more black moths and fewer white moths, since black moths have a better chance of surviving and reproducing.

Explain the role of gravity and inertia on the motion of objects in the solar system.

Answers

Like all objects with mass, planets have a tendency to resist changes to their direction and speed of movement. This tendency to resist change is called inertia, and its interaction with the gravitational attraction of the sun is what keeps the planets of the solar system, including Earth, in stable orbits.

why do you suppose the stomach contains acid? what do you think happens when there is more acid than food in the stomach?

PLZ help I need an answer ASAP
50 points to the first person!!!!!

Answers

Answer:

Your stomach acid helps you break down and digest your food. Sometimes, a higher than normal amount of stomach acid can be produced. This can lead to symptoms like abdominal pain, nausea, bloating, and heartburn.

Explanation:

brainliest plz

Answer:Stomach acid, or gastric acid, is a watery, colorless fluid that’s produced by your stomach’s lining.It’s highly acidic and helps break down food for easier digestion. This helps your body absorb nutrients more easily as food moves through your digestive tract.In order to break down everything from meat to tough, fibrous plants, stomach acid has to be highly acidic.Your body is designed to handle normal levels of stomach acid so it doesn’t cause you any illness or health complications.

Explanation:Stomach acid encounters a lot of things on behalf of your body. It breaks down the foods you eat into easier-to-digest particles. It also acts as the first line of defense against pathogens and microbes that could make you sick.

Answers

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increase. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
