Answer:
Answer is bile
Cholecystokinin is secreted by cells of the upper small intestine. Its secretion is stimulated by the introduction of hydrochloric acid, amino acids, or fatty acids into the stomach or duodenum. Cholecystokinin stimulates the gallbladder to contract and release stored bile into the intestine.
do metabolism and reproduction
Answer: Nuclear Envelope
Explanation: The nuclear envelope (NE) (also known as the perinuclear envelope, nuclear membrane, nucleolemma or karyotheca) is a double lipid bilayer that encloses the genetic material in eukaryotic cells. The nuclear envelope also serves as the physical barrier, separating the contents of the nucleus (DNA in particular) from the cytosol (cytoplasm).
Answer:
C. wavelengths of light and the rate of photosynthesis
Explanation:
The experiment by Theodor W. Engelman demonstrated the relationship between wavelengths of light and the rate of photosynthesis.
Various experiments have reported that the optimal regions of white light that drive photosynthesis is the red and blue regions.
During photosynthesis, carbon dioxide and water is utilized to synthesize glucose and oxygen is produced as a result. Hence, the rate of production of oxygen is directly proportional to the rate of photosynthesis.
<em>Therefore, the more the photosynthesis rate, the more the oxygen produced and the more the growth of aerobic bacteria. This is why more bacterial growth was observed around the red and blue region of white light according to Engelmann's observation.</em>
The correct option is C.
