The cycle runs like this:
Deoxygenated blood enters from the body to the heart via the superior/inferior vena cava. It goes directly to the right atrium and down to the right ventricle. From there it'll pass through the pulmonary artery into the lungs where diffusion will happen in the capillaries. Gas exchanges will occur and the blood will become oxygenated and return to the heart via the pulmonary vein. From the pulmonary vein it will enter back into the left atrium and then will give the final pump of oxygen rich blood into the aorta and then into the entire body.
The correct answer for this question would be the third option. The statement that correctly compares the benefits of two forms of renewable energy is this: <span>Solar power and wind power are both clean energy sources. They are considered as clean and renewable energy because both are natural energy and are always available. Hope this answer helps</span>

Answer:
K-strategists
Explanation:
Reproductive pattern in organisms can be typically categorised into two:
1. K- Strategy
2. R- Strategy
K-strategists are organisms that lives in very stable environments and gives birth to fewer organisms. Most of these organisms reproduce close the carrying capacity of their habitat. They offer support and protection to their progeny to the points where they become indepedent. The mortality rate is very low in such organisms and so is the birth rate too.
R-strategists are organisms whose main aim is to populate and dominate an environment. They reproduce exponentially and offers no life support to their progeny in their early developmental stage. They often occupy unstable and highly unpredictable environments. Most R organisms have a very low and short life expectancy. Since they produce more offspring and they live under adverse environments, mortality rate is high.
Examples of K-strategists are elephants and man
Examples of R-stategists are grasses and microbes.
