Answer:
It is the adaptation to the limiting factor temperature.
Explanation:
The presence of long ears is the most astonishing characteristic of jackrabbits. These long ears are the jackrabbits' adaptation to their native desert habitat, which helps them to cool down the temperature of their body. The ears allowed them to do so as they are thin and possess an extensive mass of blood vessels. When the temperature of the desert becomes hard to hands, the long ears of jackrabbits allow them to enhance the flow of blood via the ears by dilating its blood vessels. This dilation helps to deflect heat from the body and thus cools the creature.
It could be either Carbon has 4 valence electrons and can form many other molecules, or that it has the ability to form a variety of single, double and triple bonds. Both are true and both show complexity of organic compounds.
The statement in the beginning of the question, "scientists have found that although plants require light to carry on photosynthesis Very high levels of sunlight can kill some plants" suggests that there is a certain range of levels of sunlight that plants can survive in. Therefore, only choice B. with a specific range of conditions is supported by the evidence. Hope I could help.
LIRs take place in stroma of chloroplast; and they produce carbohydrates; CO2 is fixed; to RuBP (a 5-C compound); by Rubisco; to form an unstable 6-C compound; which splits into 2 molecules of glycerate-3-phosphate; LDRs produce ATP and NADPH; of which ATP provides energy to reduce glycerate-3-phosphate; to triose phosphate; whilst NADPH provides hydrogen required to do so; Some 3-C sugars go to form hexose sugars; others make more RuBP; (Calvin cycle);
