Describe the flow blood through the heart of human beings
gud mrng y'all
Answer:
Heyy
Explanation:
Deoxygenated blood from different organs comes to the right atrium through the vena cava.
From the right atrium, blood goes to the right ventricle. The tricuspid valve between the right atrium and right ventricle prevents the backflow of blood.
From the right ventricle, blood goes to the lungs through the pulmonary artery.
Inside the lungs, carbon dioxide is removed from the blood and oxygen enters the blood.
From the lungs, blood goes to the left atrium through the pulmonary vein.
From the left atrium, blood goes to the left ventricle.
From the left ventricle, blood is pumped into the aorta so that it can be supplied to different organs.

Which advantage of reproduction does the graph show? Explain!
The explanation regarding the advantage of reproduction that represents the graph should be described below.
Advantages of reproduction:
Here the graph represents the bacteria population that should be raised as the time passes. At the time of 1st hour, the bacteria population should be 50 per ml.
In the second hour, the population should be doubled. In the third hour it should be 200 per ml and in 3 and half hours, the population should be 300 per ml. So here we can see that the population should be doubled with every hour.

Explanation:
A state agency wants to release endangered hawks but needs to determine the best site for their release. The state would like to know how many rabbits are in each area to determine which area has the largest prey population. Create a plan to determine how many rabbits are in each area to determine which site is the best location. Your plan should include specific information on how many animals will be tagged and how many samples should be taken to get the most accurate results. Use your simulation data to help you develop this plan
We choose that site which have large number of rabbits because rabbits are the food of hawks.
Which location should be selected?That site should be considered the best which has large number of rabbits because rabbits provide food for hawks so increase in population occurs in that location. We know that rabbits are the food of hawks so without suitable amount of food, the population of hawks is unable to increase.
So we can conclude that we choose that site which have large number of rabbits.
