Answer:
a. they can fix carbon at the lower CO2 concentrations that develop when the stomata are closed
Explanation:
C4 plants are those that have the capacity to fix CO2 even when a tiny concentration of it is available.
Desert condition is characterized by dryness and strong heat with both condition capable of creating water stress in plant as a result of evapotranspiration. In order to reduce evapotranspiration rate, desert plants (most C4 plants) close their stomata during the day.
<em>Stomata closure limit the diffusion of CO2 into desert plants and the small concentration of CO2 that results is utilized by a special enzyme in the plants.</em>
The correct option is a.
What is the choices for the blank?
Answer:
6. Homeostasis
Explanation:
Definition of homeostasis
<h2>Answer is option "1 B & 2 C"</h2>
Explanation:
- Evolution genetics is a field of science, which includes the study of genetic variations that lead to evolutionary changes in organisms
- As some bacteria had changed their DNA that led to the development of antibiotic resistance in them
- Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them
- Hence, the right answer is option 1 B and 2 C " evolution Genetics & less bacteria becoming resistant to the specific antibiotics"
