This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. ... This is due to the higher forces needed to pump blood through the systemic circuit (around the body) compared to the pulmonary circuit.

The walls of the atria are thinner because the atria doesn't need to pump blood to the whole body, it only needs to transport it to the ventricles.

What is the force of an object that needs a force 4500N to accelerate it at a rate of 5 m/s
babunello [35]

Answer:

The question is somehow not correct, it suppose to be what is the MASS of an object that needs a force 4500N to accelerate it at a rate of 5 m/s as gotten from another website.

The correct answer is 900kg.

Explanation:

To get the mass of the object use the formula

F=Ma

Where F is force

M is mass

a is acceleration.

F= 4500, M=? a=5m/s

4500= M× 5

M=4500/5

M=900kg

Mass is in kg

The statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.

<h3>What is Calvin cycle?</h3>

Calvin cycle of photosynthesis is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms.

The Calvin cycle also called light independent or dark reaction is the second stage of the photosynthetic process. It is so called because it does not require light to occur.

The Calvin cycle makes use of the products of the light stage (ATP and NADPH) to synthesize carbohydrates.

However, the series of reaction is an energy consuming one, which makes use of ATP to occur.

Therefore, the statement that is true regarding the reactions that occur in the Calvin cycle is that it consumes energy.
