Why is the countercurrent system of flow important for fishes?
Question: Why is the countercurrent system of flow important for fishes?
Explanation and answer: Fishes use a design called 'countercurrent oxygen exchange' to maximize the amount of oxygen that their blood can pick up. They achieve this by maximizing the amount of time their blood is exposed to water that has a higher oxygen level, even as the blood takes on more oxygen.

At room temperature, dry ice (carbon dioxide, CO2) changes directly from solid to gas. What happens as the solid dry ice turns into carbon dioxide gas?
A.CO2 molecules lose mass to become gas.
B.CO2 molecules release heat energy to the air.
C.CO2 molecules absorb heat energy from the air.
D.CO2 molecules react with oxygen and become gas.
Answer:
A
Explanation:
Carbon dioxide is a gas at room temperature.
When the solid dry ice turns into carbon dioxide gas, the carbon dioxide molecules release heat energy into the air. Thus, the correct option for this question is B.
What happens when the solid dry ice turns into carbon dioxide gas?When the solid dry ice turns into carbon dioxide gas, the process of sublimation occurs. This process of sublimation significantly converts the dry ice into a gas in the form of water vapor.
It may be revealed that dry ice is known for carbon dioxide in its solid state of matter. The unique property of this dry ice is that it ultimately turns from a solid to gas at room temperature. This is because it provokes water vapor in the air to be condensed into droplets of water thus constructing a fog appearance.
Therefore, the molecules of carbon dioxide release heat energy into the air. Thus, the correct option for this question is B.

Answers:
D) According to the graph, obesity and diabetes are intertwined, which could be why obesity and diabetes are linked.
E) Diabetes had the greatest rise in prevalence in 1997 until 2000, with prevalence percentages between about 76% to 78%.
Explanation: Explanation for these answers are below:
D) Looking at the graph, obesity and diabetes had similar prevalences in 1997 and 1998, and started to part ways a little in 1999. In fact, even without the graph, scientists have known for a long time that people who have obesity also have diabetes. This graph supports that claim because of how closely linked diabetes and obesity are and how similar the prevalence percentages are.
E) Diabetes had the greatest rise in 1997 to 2000, which had a 78% prevalence by 2000. Obesity had very similar prevalence percentages from 75.5% to 77% in 1997 to 2000.

Which best describes how human circulatory and respiratory systems interact
Answer:
When a person inhales, the lungs expand and fill with fresh air. The respiratory system interacts with the circulatory system to transfer oxygen from fresh air to red blood cells in the lung arteries while also releasing carbon dioxide from the blood into the air in the lungs. When a person exhales, this used air leaves the body.
Explanation:
In a multicellular organism, it is cell-to-cell communication that allows the trillions of cells to coordinate activities, including during development and regeneration. The three stages of cellular communication include: reception, transduction, and response. This study determined the key steps of a cell communication pathway involved in salamander limb regeneration. After amputation of a front salamander limb, the severed axons retract within the stump and grow back along the nerve sheath. To elucidate the molecular mechanisms, the researchers set up a series of controlled experiments to determine the events in salamander limb regeneration. Drag the general cell communication steps of the regeneration experiment into the correct order.
The process of amputation will interfere with the ability of cells to communicate with each other.
What is cell to cell communication?The body of whole multicellular organisms have a lot of cells which are differentiated hence they perform diverse functions. The essence of cell differentiation is to allow different cells to perform different functions.
The question is incomplete hence we can not give here the process of cell regeneration. However, we know that the process of amputation will interfere with the ability of cells to communicate with each other.
