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:
- According to the cladogram what separates rabbits/primates from crocodiles is that the former have a divergence before the latter and are viviparous.
- The organism that is most closely related to rodents and rabbits in the cladogram is the primate.
Explanation:
The cladogram (see image) shows the evolutionary line that several animal species have followed. According to this, the following conclusions can be established:
- <em>Both primates and rabbits/rodents are mammals, with intrauterine development of their offspring, while crocodiles and birds are oviparous, which represents a </em><em><u>divergence in their evolution</u></em><em>.</em>
- <em>The species most related in the cladogram to rabbits / rodents is the primate, since they share several characteristics in common, such as being mammals, skin covered with hair and being viviparous.</em>
Characteristics such as these are what allow the classification of different animal species.

splitting of sister chromatids and the moving of them to opposite poles inside the cell.
Answer:
Explanation:
The human body stores energy through different forms. One of it is by organic food molecules that contains sugar, fat and proteins which are rich sources of energy. Whenever the body doesn’t have enough energy to pull through, it uses these reserves of energy. The molecules start a smart process because instead of releasing all the energy at one, it slowly releases little by little in a process called oxidation (for the body not to run out of energy at once).
