A: In a lab a scientist measures the height of roses that received different fertilizers.
An experiment must include variables. The other three are just measurements, but since the scientist is varying the types of fertilizers used, this better describes an experiment. It is also done in a controlled environment (in a lab) which helps to eliminate other uncertainties.
A neutron is one of the three subatomic particles, between electrons and protons it has no charge since it is neutral.
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.
