Where does carbon dioxide move from the circulatory system to the respiratory system? A. In the vena cava B. In the alveoli C. In the liver O D. In the pulmonary artery
In the alveoli, carbon dioxide move from the circulatory system to the respiratory system.
Where does carbon dioxide move from the circulatory system to the respiratory system?The circulation receives oxygen from the lungs during gas exchange. The blood and lungs exchange carbon dioxide at the same time. This occurs in the lungs between the capillaries, which are a network of microscopic blood arteries found in the walls of the alveoli, and the alveoli themselves.The body's cells are supplied with oxygen and nutrients through the heart, blood, and blood vessels. Blood transports carbon dioxide to the lungs (for exhale) and picks up oxygen through the network of arteries, veins, and capillaries.While carbon dioxide flows from the blood in the capillaries to the air in the alveoli, inhaled oxygen moves from the alveoli to the blood in the capillaries.learn more about alveoli here: https://brainly.com/question/4539268

In north carolina, demand for fresh water has increased dramatically. one of the main reasons for this is increased water use for agriculture. respond to the following in 3–5 sentences:
relate one effect of agricultural water use on north carolina's river basins.
relate one conservation strategy that would reduce the effect of agricultural practices on water quality.
Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.
What are the effects of irrigation agriculture on river basins?Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.
Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.
One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.

D
Answer:
Answer is A
Explanation:
If you know about the energy pyramid, you would know that producers are at the bottom. Abiotic factors are factors that are non-living. Some examples are water, rocks, and the sun. Plants use energy from the sun to make food. Since the sun is an abiotic factor, it would make more sense that producers get their energy SOLELY FROM AN ABIOTIC FACTOR ( THE SUN ).

Why do living things reproduce?
Answer:
Organisms reproduce to continue the chain of life.
Reproduction is essentially a process by which individuals produce new individuals of the same kind. And this process is very important for the existence of life on earth.
Whether the organism is a rabbit, or a tree, or a bacterium, life will create more life. If a species cannot create the next generation, the species will go extinct.
3. Which type of photosynthesis is not reliant on the presence of light to be efficient?

However, all of the mice seemed to grow at a faster rate then the control group. Which statement describes the most likely outcome of this investigation?
The knowledge gained will lead to further experimentation that could potentially result in a new use for the drug.
He will develop a second experiment to find a way to make the drug successfully lower blood pressure in mice.
The data he collected will be used in new investigations to determine why certain people are taller than others.
He will use these results to conclude that the drug will most likely lower blood pressure in five percent of people.

The organism P. malariae lives in red blood cells, causing the host organism to experience high fevers and chills. What type of relationship is this? a. Mutualism b. Commensalism c. Parasitism d. Competition Please select the best answer from the choices provided A B C D
The relationship between the organism P. malariae that lives exploiting the human host is parasitism because the human body suffers high fevers and chills from this interaction (Option C).
What is parasitism?Parasitism is an ecological relationship in which the invader organism (i.e. the parasite) is benefited, while the host organism (in this case the human host) is harmed.
Therefore, we can conclude that parasitism is a ecological relationship in which the parasite is benefited from such interaction while the host is harmed, which is in this case represented by the organism P. malariae and human hosts.
