In systemic circulation, a drop of blood that is rich in oxygen in the left atrium will first travel through the bicuspid valve to reach the left ventricle. From there it will be pumped through the aortic semilunar valve to reach the aorta which will branch into arterioles.
The blood exiting the capillaries is poor in oxygen and will first travel in venules, which will fuse into bigger veins. Eventually the blood will enter into the right ventricule via either superior vena cava or inferior vena cava.
<h3>What is Systemic circulation?</h3>
This involves blood vessels supplying oxygenated blood to and returning deoxygenated blood from the tissues of the body.
The appropriate processes and steps can be seen above.

I'm going to guess that it's the second option, "New matter only enters the biosphere in the form of precipitation" because it bothers me that the writer said "new matter" and everything else seemed right to me.
The last two are definitely true. I'm a bit iffy about the first option because I know that autotrophs take the energy from the sun, then primary consumers eat them and then everything eats one another afterwards. So everything moves from the bottom of the food pyramid up. There are decomposers which take dead matter from any trophic level and bring it up, which, I guess, is still in the same direction on the food pyramid.
New matter can probably enter the biosphere in other ways like a meteor hitting the earth or something. The water from precipitation never left the biosphere, so that's where it's wrong.
I hope this helps.
Answer:
b. Vernalization
Explanation:
Vernalization is a phenomenon in which plants require low temperature for the flowering. There is either qualitatively or quantitatively dependent on exposure to very low temperature. This process is known as vernalization. Vernalization defines especially to the promotion of flowering by a period of low climate. For example; Vernalisation occurs in biennial plants. Biennials are monocarpic plants which normally flower and may die in the second season. Some common examples of biennials are carrots, Sugarbeet, cabbages, etc.
Answer:
It does not dive them what they want or need.
Explanation:
In natural selection it is the complete opposite. In natural selection the animal has to adapt to the environment with all of the traits it has or develop another trait. If it doesn't adapt then the popular saying "Survival of the fittest" becomes true.
