Answer:
The correct answer is - option B. the cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.
Explanation:
The cell membrane is the most essential cell organelle that is mainly responsible for the regulation of homeostasis of the cell. It acts as a barrier between the outer environment and cell components are enclosed in the cell organelles and cytoplasm by regulating the movement of the material in and out of the cell.
This movement can be active or passive transport depending on the nature of the material as it is a selectively permeable membrane.
The correct answer is - option B.
Answer:
Evaporation increases with an increase in temperature
.The water molecules move rapidly when the water is heated. This makes the molecules escape faster. Higher temperatures lead to increase in vaporization as more molecules get kinetic energy to convert into vapor.
Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars.
Answer:
Talons
Explanation:
Talons are an owl's primary weapon for catching its prey. When an owl catches its prey, two of its talons go forward and two go backwards to ensure that when the prey is caught, it cannot escape.
