Which of the following statements is the most likely explanation for plant withering due to leaky membranes in cold temperatures
podryga [215]

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.

Energy is said to flow in a “one way stream” through an ecosystem. in your own words, describe what that means.
Dominik [7]
The energy not used by an original organism being consumed is being transferred "flowing" to the organism that is consuming the original one, thus being the flow of energy throughout an ecosystem.

Brian is a 15-month-old male whose screening hemoglobin is 10.4 g/dl. treatment for his anemia should be:
schepotkina [342]
<span>Hemoglobin is the part of the red blood cell that carries oxygen, and so important for thriving. In the case of Brian, having 10.4 g/dL hemoglobin is very low. Normal values for hemoglobin in males range from 13.5 to 17.5 g/dL. The patient has very serious anema and note he is just 15 months old, and so needs immediate doctor’s attention. The doctor is likely to order a blood transfusion to elevate hemoglobin levels and stabilize the patient before ordering tests to determine cause of anemia.</span>
