The cardiovascular system is sometimes called the blood-vascular, or simply the circulatory, system. It consists of the heart, which is a muscular pumping device, and a closed system of vessels called arteries, veins, and capillaries.
The system that contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products. The lymph system, which connects with the blood system, is often considered part of the circulatory system.

Answers
Answer:
6g = 6mL. The gram to milliliter ratio is 1:1.

A de-shelled egg is placed in tap water. The egg grows in size.
What is the best explanation for this change in size?
Ions in the water moved into the cell through diffusion because there were more ions outside the cell than inside the cell.
Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell.
Water moved out of the cell by osmosis because the solute concentration was higher outside the cell than inside the cell.
Water moved into the cell by diffusion because there is more water inside the cell than outside the cell.
Answers
The best explanation for the change in the egg's size is that Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell. Option B.
--------------------------------------------
When talking about solutions, we can classify them as follows,
Hypertonic ⇒ A hypertonic solution has a higher concentration of solute than the cell. This means that in the cell interior, the solute concentration is lower than in the solution itself. Isotonic ⇒ The solute concentration is the same inside the cell and outside. Hypotonic ⇒ A hypotonic solution has a lower concentration of solute than the cell. This means that in the cell interior, the solute concentration is higher than in the solution itself.
Water is considered to be a hypotonic solution.
When a cell is in a hypotonic solution, through osmosis, water moves toward the cell.
Note: In this example, the egg is the cell.
Osmosis is the phenomenon that occurs when two dilutions of different concentrations -in this example, the interior of the cell and the solution- are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.
Water tends to go from the hypotonic solution to the cell interior and keeps doing so until concentrations are equal in the cell interior and exterior.
As water enters the cell, the cell begins to enlarge and becomes bigger-sized. And because cells can not limit the amount of water moving in, it keeps swelling until the membrane can not stretch anymore, and lysis occurs. It bursts.
What we need to consider is
When a cell with a semipermeable membrane is placed in a hypotonic solution, water enters the cell. When a cell with a semipermeable membrane is placed in an isotonic solution, there is no water movement. When a cell with a semipermeable membrane is placed in a hypertonic solution, water gets out of the cell.So, the best explanation for the change in the egg's size is Water moved into the cell by osmosis because the solute concentration was higher inside the cell than outside the cell. Option B.

What hypothesis might the experimenter have been testing with this experiment?
Answer Plato:
Increased levels of carbon dioxide cause air to heat up more rapidly.
Answers
Answer:
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the change in the dependent variable is observed and recorded.
Explanation:
The hypothesis that the experimenter might have been testing with this experiment is increased levels of carbon dioxide cause air to heat up more rapidly.
The experimenter is likely testing whether higher concentrations of carbon dioxide in the atmosphere lead to a faster rate of temperature increase in the surrounding air. This hypothesis is relevant to the study of climate change and global warming, where elevated levels of carbon dioxide, primarily from human activities, are believed to contribute to the Earth's temperature rise due to the greenhouse effect.
In conclusion the experiment would involve exposing air samples to different concentrations of carbon dioxide and monitoring the rate of temperature increase to determine if there's a correlation between CO2 levels and heating rate.

How does your diet (the different types of foods you eat) affect the water cycle? what types of foods use the least amount of water, and what types of food use the most water?
Answers
Answer: Your diet can probably effect. More animals may consume more water than others. Or more plants drink more water than others. by eliminating these animals, there is more water left. Some plants that use the last water is the Sago Palm, Snake plant, Orchids, Spider plant, and plenty of the plant species who are adapted to dry climats. The plants that consume the most water are Ferns, Lilys, Daylilies, Indian grass, Cattails, Iris, and Elephant ears. The animals that consume the most water is probably the biggest animals like elephants and cows, who according to my search can consume up to 100 gallons of water a day durring hot summer months. So, the least water, the less it will rain, the less clouds there would be, and the easier it would be for the land to dry out.
