Auxin, The substance responsible for cell elongation is auxin. This phytohormone is formed in cells at the tip of the shoot and is then passed from cell to cell.
Answer:
It would be difficult to recreate the exact conditions of the chemical release elsewhere.
Explanation:
Answer:
All of the above
Explanation:
ATP synthase is a transmembrane protein enzyme. It harnesses the potential energy –proton motive force- created by the development of a proton gradient across a membrane (could be across the intermembrane space in chloroplast and mitochondria). As the H+ ions 'drain' back and pass through their channels in the protein enzyme, the synthase is able to phosphorylate ADP and Pi to form ATP.
These ATPs (from photophosporylation) in light-dependent phase, are used in the catabolism of glucose, in the light-indepedent phase.
Answer:
As we get older the number of taste buds decreases.
Explanation:
Gustatory cells or the taste buds contains the different sensory cells on the tongue. The papillae consists of all the taste receptors. The sweet, bitter, salty, umami and sour tastes are recognized by the receptors.
The different individuals have different taste because of the presence of the different taste buds. The number of the taste buds decreases the individual gets older. The children has more taste buds and can easily understand the taste of different things. Hence, Joshua dislikes the broccoli taste.
Thus, the correct answer is option (a).
The answer is a hair root.
Nuclear DNA is commonly extracted from the hair root. The hair root consists of keratinocytes. Keratinocytes are cells found in the epidermis. As all other cells, they contain DNA material. When keratynocites die, they get converted into keratoid material in the process of cornification. As a consequence, d<span>ead cells do not contain DNA material. Therefore, the hair root is the best source of nuclear DNA than shed or cut hair when working with hair sample.</span>
