Answer:
The correct option is d. In C3 plants the conservation of water promotes photorespiration.
Explanation:
Photorespiration is a metabolic pathway that leads to the loss of half the carbon fixed by photosynthesis, it occurs when the rubisco enzyme (which is responsible for carrying out the carbon fixation) of the Calvin cycle acts on oxygen instead of dioxide carbon. Photorespiration occurs in C3 plants, (considered C3, by the three carbon compound) when the CO2 concentration is reduced. The first step of the Calvin cycle is the fixation of carbon dioxide by rubisco, but at low concentrations of CO2, oxygen begins to be set in place. In conditions of moderate temperatures when C3 plants have enough water, the carbon dioxide supply is abundant and photorespiration is not a problem.
A carrying capacity is the amount of people, animals, or things that fit in a particular space.
The correct answer is that the beaks would increase - this is the adaptation of finches to the new conditions (drought).
Beak depth varies according to drought conditions. Since after the drought vegetation dries out and the hard, big, tough seeds remain, only the finches with deep beaks will survive. Finches adapt via their beaks to different foods sources and different local conditions.
Answer:
Evolution
Explanation:
Evolution is the change in the inherited traits of a population from generation to generation. Mutations in these genes can produce new or altered traits, resulting in heritable differences (genetic variation) between organisms.
