Answer: B I think

Protein molecules are often very large and are made up of hundreds to thousands of amino acid units. Fats are large molecules made up of carbon, hydrogen, and oxygen, as are the carbohydrates, but their hydrogen-to-oxygen ratio is higher than 2;1. For this reason, fats contain more energy-storing carbon-hydrogen bonds than carbohydrates.

The size of the iris and pupil can change size. If you walked from a bright room into a dark room, what would happen to the size
prisoha [69]

The correct answer is B. The iris would get smaller, the pupil would get bigger.

Explanation

The iris is the name by which the colored part of the eye is known, it is located between the cornea and the lens. In the central part of the iris, there is a round opening known as the pupil. The relationship between these two parts of the eye is very important to sight because between them they control the amount of light that enters the eye. This occurs when the eye is exposed to a high amount of light, the iris muscles make the pupil smaller and the iris larger, limiting light entry into the eye. When the eye is exposed to low amounts of light or darkness, the iris becomes smaller and the pupil enlarges, allowing more light to enter. According to the above, the correct answer is B. the iris would get smaller, the pupil would get bigger. Because it describes the behavior of the iris and the pupil when going from a bright room to a dark room.

What effect would an increase in temperature have on the rate of osmosis in these cells
charle [14.2K]

Answer:

hope it helps you❤❤❤❤

Explanation: Factors Affecting the Rate of Osmosis

Temperature - The higher the temperature, the faster the movement of water molecules across the semi permeable membrane.

Osmosis is the passage of water from a low solute concentration area through a semi-permeable membrane to a high solute concentration area to equalize the solute concentrations on both sides. Meaning of the terms: solute, solvent and solution. A solvent is the base substance, where a solute is being dissolved and the result is the solution. Through osmosis, water is provided to the cells of your body; it plays a significant role in the preservation of life. It is this process that helps plants receive water and is even used in kidney dialysis.
