Under conditions of high temperature and drought stress, a plant closes its stomata to conserve water. Which of the following is the MOST DIRECT consequence on the Calvin cycle?
Increased photorespiration due to oxygen accumulation.
Enhanced ATP synthesis due to increased proton gradient.

Which of the following statements is not correct regarding Blackman’s law of limiting factors ?
The process rate is always controlled by a single, unchanging factor.
When a biological process is affected by multiple factors, its rate is limited by the factor which is in least amount relative to its requirement
If a factor is limiting, increasing its concentration will increase the rate of the process
If a limiting factor's supply is increased, some other factor will eventually become limiting
