Name the two types of vaporization and explain the difference between them. Give one example of each.
No links
please just answer correctlyyy
Answer:
The 2 types of vaporization are: Evaporation and Boiling. Evaporation takes place at the surface of a liquid, such as a puddle drying up. Boiling takes place below the surface of a liquid and causes bubbling, like a pot of water on a hot stove.

True or False. The pressure inside a piston is the same in all directions.
Answer:
True
Explanation:
Pascal's law says that pressure applied to an enclosed fluid will be transmitted without a change in magnitude to every point of the fluid and to the walls of the container. The pressure at any point in the fluid is equal in all directions.
Answer: The answers to the whole quiz to get 100% correct:

Actually, Sherman, there are more black moths than white ones because...
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.

Which describes an INHERITED TRAIT of a plant?
The broken branch of a tree
The torn flower petal
The green color of a leaf
The holes in a leaf caused by an insect-eating it.
Answer: the green color of a leaf
Explanation: because the other things are physical changes of a plant that don't get passes down to offspring
Answer:
The green color of the leaf
Explanation:
That is a trait they have by birth and is what they had passed on to them.

What are INHERITED TRAITS?
The offspring of a plant
Characteristics are passed down from the offspring to the parent.
The parent of an offspring
Characteristics passed down from parent to offspring.
Answer:
Characteristics passed down from parent to offspring.
Explanation:
Inherited traits are given to the offspring from the parents.
"Characteristics are passed down from the offspring to the parent" does not make sense.
"The offspring of a plant" and "The parent of an offspring" are wrong.
Answer:
Characteristics are passed down from parent to offspring
Explanation:
This is because that inherited means that you are given them, these traits are given to you from your parents

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!!!!!
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.
