pls help me out with this and thanks for the help

Answer:

Hey there,

The answer is A.

This is because the crust is broken into parts called plates and these plates collide with each other or separate from each other or slide past each other.

They move because they sit on top of semi molten rock in the mantle. The semi molten rock moves due to convection currents which is heated up by the core.

It’s is not option B because it does not have u form thickness through out it. For eg the continental crust is 60 km thick while the oceanic plates are wonly 10km thick.

It is not C as the mantle is semi molten not solid.

And it’s not D because it’s not a single layer but multiple layers.

So A is the answer.

I hope this helps!

Explanation:

Answer:

Normally, blood flows freely through your blood vessels, arteries, and veins. Your arteries carry blood with oxygen and nutrients to your body. Yours veins carry waste products back to the heart. In some cases, the blood thickens and clumps to form a blood clot in one of these vessels. This can block the blood flow. When blood flow is blocked, nearby tissues can be damaged.During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow. In some cases, a balloon or other device may be put in the blood vessel to help keep it open.

Answer:

B

Explanation: Decreasing the temperature will not make the increase rate at which something dissolves quicker it would only make it go slower.

Answer:

The first one

Basically the blood vessels that carry blood away from the heart are called arteries

Answer:

temperature

Explanation:

and this climate zone the warmest months average less than 10° Celsius the North and South Poles have climates that are polar because of the nearby cold air masses for climate region near the equator with warm air mass is is known as tropical so there's more has to do with temperature

Answer:

Cell membrane

Explanation:

A cell membrane is basically a protection of the cells. It controll what goes in and out of the cell and separates the interior of the cell from the outside environment. they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, etc that mediate cellular  activities to pass between organelles.

Answer:

The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.

Explanation:

Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria

If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.

When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.

Answer:

An earthquake , a forest fire , a hurricane  and a volcanic eruption.

Explanation:

An earthquake , a forest fire , a hurricane  and a volcanic eruption are the events that is responsible for the suitable conditions for primary succession because all the population of animals and vegetation are removed from an area and the new type of organisms is start to living in that new environment. These new organism has the ability to survive that environmental conditions. These events completely removed the population in the environment and provides conditions for primary succession.

Answer:

Volcano eruption

I think A makes the most sense..

Answer: 1. Aerosols 2. Small particles 3. All of the above.( all of those chemicals are harmful to humans)

Explanation: I took the test :D Here you go!

Answer:

Large solid food particles are breakdown into small simper food molecules.

Explanation:

Digestion is the process in which large solid food particles are breakdown into small simper food molecules so that they can be absorbed by the body and added to the blood plasma. These simpler molecules are absorbed by the cells to generate energy in the form of ATP. This transformation from solid food particles into simpler molecule through mechanical and chemical digestion. Mechanical digestion starts from the mouth in which the sold big particles are changed into smaller pieces with the help of teeth while on the other hand, the chemical digestion occurs through digestive juices that helps in break down.

Explanation:

Biodiversity is the variety of life in a habitat or ecosystem

Explanation:

There are many different systems involved in when we exercise, the three main ones are the Respiratory system which is involved in breathing the circulatory system which is about circulation of blood around the body and finally the muscular system and finally the Muscular system which is about how we move.

Answer:

Due to the presence of suitable environment.

Explanation:

Suitable environmental conditions are responsible for the presence of large amount of species in water bodies because suitable environmental conditions provides necessary materials for the growth and survival of organisms. The marine environment that have sufficient amount of food, space, optimum temperature, pH and salt concentrations so in this environment more number of species are present due to increase in population as compared to those ecosystem having harsh environmental conditions.

Answer:

By moving water from the vascular system into the tiny feet, the sea star can make a foot move by expanding it. This is how sea stars move around. Muscles within the feet are used to retract them. Each ray of a sea star has a light sensitive organ called an eyespot.
