Answer:
(B) open stomata only at night, limiting water loss because of heat and low humidity.
Explanation:
CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.
They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.
During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.
Answer:
A) results in evolutionary adaptation
Explanation:
Natural selection is the process in which organism with specific traits are able to survive than others. Natural selection allows the fittest to survive while eliminating the others. It prepares the species for environmental changes by resulting in evolutionary adaptation.
Evolutionary adaptation occurs when species goes through certain processes (hereditary, habits, Physical structures) to become fit in environment. These changes help the organism to evolve to adopt the changing environmental conditions.
Example; Sweating in human.
Answer:
The application of biotechnology in agriculture has resulted in benefits to farmers, producers, and consumers. Biotechnology has helped to make both insect pest control and weed management safer and easier while safeguarding crops against disease.
