Answer: Abrasion
Abrasion is a geological phenomena in which weathering and erosion of the rocks or other hard surfaces by physical agents like water and wind. In this process, the surface material is scrapped, scratched and wear down by the frictional force exerted by the physical agents.
The sawing and grinding action of the rock fragments in the water is called as abrasion because here the water is the physical agent affecting the physical structure of the rock.
Homeostasis refers to the mechanism of the body to maintain a stable internal environment instead of changes taking place in the external environment.
The balance that is attained is called dynamic equilibrium, which means as the changes occur body work to maintain a relatively uniform conditions.
The maintain that equilibrium body control temperature, blood pH, amount of blood in the glucose are ways of body to maintain homeostasis.
Answer:
Pigments absorb the light (capture as much light energy as possible) used in the process of photosynthesis.
Explanation:
Photosynthetic pigments are chemical compounds that absorb and reflect certain wavelengths of visible light, that is, they absorb light and have a color.
They are vital components for the process of photosynthesis, the most important pigment is chlorophyll. Chlorophyll is a large molecule, which captures the energy of sunlight and converts it into high-energy electrons. This occurs during the light reactions of photosynthesis, while high-energy electrons are subsequently used during dark reactions in the synthesis of glucose.
During passive transport, energy is used to move material against a concentration gradient.
During active transport, water is pumped across a membrane to equalize the concentration of salts on both sides.
During passive transport, osmosis allows salts to move from one side of the membrane to the other to equalize concentrations on both sides.
Answer;
A. During active transport, a material may be moved from an area of low concentration to an area of high concentration.
Explanation;
-Active transport involves movement of molecules or particles against a concentration gradient (from a region of low concentration to a region of high concentration). This movement of particles against the concentration gradient requires an input of energy from the cell in the form of ATP.
- Passive transport on the other hand involves movement of materials from a region of high concentration to a region of low concentration and does not utilize energy. Passive process are processes such as osmosis and diffusion.

An enzyme's structure determines its function, stability, and activity.
An enzyme's structure directly affects its function. Enzymes are proteins made up of chains of amino acids. The specific sequence and arrangement of these amino acids determine the three-dimensional shape of the enzyme, which in turn determines its function. For example, the active site of an enzyme is a small pocket or crevice that allows the enzyme to bind to its substrate and carry out a specific chemical reaction.
The structural characteristics of an enzyme also affect its stability and activity. Changes in temperature, pH, or salinity can alter the shape of the enzyme, rendering it inactive or less efficient. Additionally, certain environmental factors may denature the enzyme, causing it to lose its shape and functionality permanently.
