PLEASEE ANSWER BEFORE FRIDAY APRIL 30 Seven students looked at a barometer, a weather device that measures air pressure. They had different ideas about air pressure. This is what they
thought:
Kimberly:
Glenn:
Rae:
Jeff:
Oliver:
I think air has to be moving to create air pressure.
Air pressure is a downward force.
The higher in the atmosphere, the greater the air pressure.
Air pressure is the same in all directions.
Air pressure increases as the number of air particles increases.
Warm air masses have higher pressure than cool air masses.
When air pressure decreases, it might rain or snow.
Cameron:
Jay:
Circle the names of the students you agree with and describe why you
agree. Describe your ideas about air pressure.

Answers

Answer: pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. ... Meteorologists describe the atmospheric pressure by how high the mercury rises.

through an energy pyramid.

Answers

So the sun gives energy to the producers (plants) and then the primary consumers eat the producers getting their energy from the plants. Then, the secondary consumers eat the primary consumers getting their energy from the primary consumers and finally the tertiary consumers eat the secondary consumers getting their energy from them. Therefore, the entire energy pyramid starts with the sun!

Answer:

The answer is C.

Explanation:

There are dominant alleles present in three out of four (CC, Cc, Cc) and the recessive is always cc. Three out of four make 75% and one out of four is 25%. That makes 75% dominant and 25% recessive.

I hope this helps!

Conserving: It’s important to keep our environment safe. It effects both us and animals. One way you can that conserve the environment is by protecting the environment and volunteer in programs that help do so.


Cleaning up: This is very vital to the environment. The amount of trash and litter is insane. Animals on sea or land can eat the trash, thinking that it’s food and can either choke on it and get sick. It also can destroy the plants of the environment, it can even affect humans, like for example a toddler might pick a piece of plastic of the ground and choke on it.

Chiming In.
In order to conserve and protect the environment, we need willing participants that will provide help for the task. Volunteer in beach clean ups, or go to an local park and pick up all the trash. You can also do help without volunteering by just doing the bare minimum, (throwing your trash away in the can, recycle, and encourage those around you to do the same)

A population is a group of individuals of the same species. According to the theory of natural selection, what is likely to happen to a population when a change occurs in its environment (for example, the amount of rainfall decreases or the temperature increases)?
A.All of the individuals would try to develop new traits so that they could survive and reproduce in the changed environment. B.Some of the individuals would try to develop new traits so that they could survive and reproduce, and the other individuals would die. C.Because all individuals of the same species have the same traits, one individual would never have an advantage over another in its population.They would either all survive or all die.D.The individuals that have traits better suited to the changed environment would be more likely to survive and reproduce than those with less suitable traits.

Answers

Answer:

The answer is D.

Explanation: As everyone knows, "survival of the fittest" is a common thing. When an environment is disturbed or has some changes, the effects vary from one species to another and the ones who have traits that can help get through or adapt to these changes will most likely survive.
