Answer:
When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbon dioxide is dissolved in the blood, carried to the lungs by the circulation, and breathed out.
Answer:
because our bodies take in O and put out CO2
Explanation:
O is Oxygen
and CO2 is Carbon dioxide
How would blood flow be affected if the aorta decreased in diameter?
Answer:
A decreased diameter means more of the blood contacts the vessel wall, and resistance increases, subsequently decreasing flow. The influence of lumen diameter on resistance is dramatic: A slight increase or decrease in diameter causes a huge decrease or increase in resistance.

What are the 3 types of plate boundaries? Describe each.
Explanation:
Divergent boundaries -- where new crust is generated as the plates pull away from each other.
Convergent boundaries -- where crust is destroyed as one plate dives under another.
Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
The two lower chambers of the human heart are known as:
a.
atriums
c.
auricles
b.
ventricles
d.
blood vessels
Answer:
b. ventricles
The right and left ventricles
Answer:
B(ventricles)
Explanation:
So lets go over the heart.
First blood circulates from your body to your heart. This is through blood vessels. These blood vessels are connected to the inferior and superior vena cava that go into the heart.
So, this means that the blood vessels are outside of the heart, not the lower areas.
Then, the blood goes into the right artierium, and down to the right venticle. So, thinking about this, it means that the artieriums are the top chambers.
The word auricles is another word for artiums, which we already know are the top chambers.
The venicles are below this, these must be the bottom chambers.
I attached files of some notes I took on the heart, they show the strucutre of the heart and the workings of the heart and circulatory system.
Hope my answer or notes helps! ;)

Describe the advantage of broad-leaved trees losing their leaves as winter sets in and the advantage of needle-leaved trees keeping their leaves if they are in poor soil
Answer:
The advantage of shedding broad leaves in the winter is to conserve the energy that needs to expand in order to provide heat to each part of the plant including leaves as in winters it becomes very dry and cold. If they do not shed their leaves they have to spend more energy to spend energy on leaves.
Needles like leaves have a thick cuticle layer that prevents from losing water in dry conditions or conditions with a limited amount of water in the soil. These leaves also help in photosynthesis by capturing more sunlight as they have a larger surface area. These adaptions can live in poor soil, rain and snowy conditions.
Many farmers keep their chickens in sheds.
They claim that their chickens grow larger when kept in sheds rather than outside in fields.

1. Which statement below best describes an eclipse?
A. An eclipse happens during new moon when the moon is shadowed.
B. An eclipse is part of the moon phases occurring every month.
C. An eclipse will last for a couple days and then return to normal.
D. An eclipse is the only time the Earth shadows the moon.
Answer:
D. An eclipse is the only time the Earth shadows the moon.
Explanation:
The other ones doen't make sense, the true definition of an eclipse is: That the eclipse is an phenomenon (sorry if the word is wrong but i'm Latina) in which the light coming from a celestial body is blocked by another eclipsing body.

Hello. Your question is incomplete. The complete question asks for the correct answer to be found based on Catalase is an essential enzyme in living beings since all cells need it.
Answer:
B. Cells only function within a specific temperature range because enzymes only function within a specific temperature range.
Explanation:
Catalase needs to be present in all cells of the living organism because it is responsible for the decomposition of hydrogen peroxide that cannot stay inside cells for long periods of time. Following this type of reasoning, we can say that it is necessary to maintain a constant temperature for the enzymes of an organism to function well because all enzymes have a specific temperature range, even catalase.
The specific temperature range determines that the enzymes will only work within that range. Therefore, an environment where the temperature is below or above that specific range, can prevent the enzyme from functioning and even cause irreversible damage to the enzyme.
