The existence of evolutionary trends, such as increasing body sizes among horse species, is evidence that

#Unit 11. Evolution and Behavior
  1. a larger volume-to-surface area ratio is beneficial to all mammals.

  2. an unseen guiding force is at work.

  3. evolution always tends toward increased complexity or increased size.

  4. in particular environments, similar adaptations can be beneficial in more than one species.

In greenhouse grown leaves of broad bean stomatal movements closely correlate with incident solar radiation at the leaf surface and stomatal aperture  opening and closing as light levels reaching the leaf surface given in graph

 


A. Mid of the day stomatal aperture has a largest diameter, water loss and transpiration rate will be highest at the  same time

B. In mid of the day incident light is highest in terms of PPFD and can also say CO2 diffusion will be highest

C. The stomatal aperture has a largest diameter resulting closing of stomatal pore, water loss and transpiration rate will be lowest due to closing of stomata

D. In mid of the day incident light is highest in terms of PPFD resulting CO2 will not diffuse

which of the following combination from the given graph will be CORRECT?
