Answer:
The appropriate choice is C) random
Explanation:
A random distribution denotes a kind of spread where individuals are dispersed without any discernible pattern. An example would be seeds scattered by the wind. The wind displaces the seeds, causing them to land sporadically in various locations, hence this is identified as random dispersion.
Other options are incorrect; for instance, option A is wrong since wind dispersal does not exhibit a consistent distribution pattern.
Answer: Enzymes reduce the activation energy associated with food molecules
Explanation:
Chemical entities such as yams, potatoes, eggs, etc., consist of elements linked together by chemical bonds like hydrogen bonds and covalent bonds.
To facilitate digestion, these bonds must be disrupted in order to convert carbohydrates into glucose and proteins into amino acids.
Therefore, when enzymes are introduced, they lower the bond strengths or activation energies by positioning them appropriately in their active sites, designed to cleave specific bonds.
As a result, digestive processes become faster in the presence of enzymes compared to without them.
Answer: Amylase
Explanation: it’s an enzyme found in saliva that facilitates the breakdown of starches, such as those present in pasta, aiding in food digestion.
Renal glucose reabsorption.
Answer:
TRUE
Explanation:
Green plants possess chlorophyll, a green pigment in their leaves. Chlorophyll can absorb the sunlight required for photosynthesis to occur. Photosynthesis refers to the process by which green plants produce food in the presence of light, water (H₂O), and carbon dioxide (CO₂), resulting in the release of glucose and oxygen (O₂) needed for the survival of all living beings.
The reaction that occurs during photosynthesis is illustrated below-
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This method converts light energy into chemical energy, which is stored in glucose molecules.
Consequently, the statement is TRUE.
