"Why does the water table change throughout the year in a wetland?"​

Answers

Because, precipitation patterns are changing. The changes would cause water availability to decline, and the depth of the water table would shrink.

As temperatures rise, potential evapotranspiration will also increase. In addition, precipitation patterns are changing. The changes would cause water availability to decline, and the depth of the water table would shrink. In some of the wetlands, the water table could retreat by more than eight inches.

3. An expansion of suitable living space

Explanation:

Increase occurs in the population of the organism only occurs when there is a suitable environment present for that organism. Suitable environment means that place where all the needs of the organism are available such as food, water and shelter etc. If food and water are present in large amount and decrease in animals occurs that prey on that organism will increase the population of the organism.

Fat are for long term energy & Carbohydrates are for short term energy. Lipids are for long term energy & Carbohydrates Sugars are for short term energy. The correct options are A and C.

What are lipids?

Lipids are fatty compounds that serve numerous functions in your body. They are part of your cell membranes and help regulate what enters and exits your cells.

They aid in the movement and storage of energy, the absorption of vitamins, and the production of hormones. Some lipids are harmful in excess.

Fats are the body's primary long-term energy storage molecules. Because fats are compact and light in weight, they are an effective way to store excess energy.

Carbohydrates provide short-term energy while fat provides long-term energy. Carbohydrates and Lipids are for long-term energy. Sugars provide quick energy.

Thus, the correct option is A and C.

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.

Explanation:

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells.

What are the functions of enzymes?

An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.

Enzymes help speed up chemical reactions in the human body. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles. Each cell in the human body contains thousands of enzymes.

The function of enzymes is to carry out critical tasks. These involve muscle growth, removing toxins, and tearing down the molecules in food throughout digestion.

A white blood cell with an internal solute concentration of 0.9% is placed in a solution of concentrated salt
water of 5%. Describe what will happen to the white blood cell in this solution

Answers

The 5% salt water is hyperosmotic to the cell’s internal 0.9% solute concentration. The salt (presumably sodium chloride in this case, but this would also apply generally to soluble salts in the chemical sense) in salt water exists as solvated ions; the solutes within the cell’s cytoplasm consist of proteins, nucleus acids, other molecules, and also salts. However, the cell membrane is generally impermeable to all of these substances.

On the other hand, the cell membrane is permeable to water, which can thus diffuse through the cell membrane. An osmotic gradient exists due to the difference in solute concentrations—there is “less” water relative to solutes in salt water than within the cell. Water will thus be pulled out of the white blood cell’s interior and into the external salt water solution. The result will be a shrunken and shriveled white blood cell with an internal solute concentration that is equal (or as close as possible) to the solute concentration of the salt water.
