Answer:
C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.
Explanation:
Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.
In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.
Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.

Answer:
D
Explanation:
The cuticle of a plant helps protect its aerial epidermis from things like environmental stresses and desiccation.
<u>Answer</u>:
1. Type of medium - the nutrient availability is one of the vital factors for the growth of a bacterial colony. Thus, the used growth medium will fulfill this requirement.
2. Incubation temperature - all bacteria have an optimal temperature range in which maximum growth is achieved. Any variations from this will result in negative effects on the amount of bacteria that are produced.
3. Moisture - bacteria thrive in moist or wet environments. Thus, the availability of moisture is another vital factor for the growth of the colony.
