CAM is a special photosynthetic pathway found to be present as adaptation within:a)Photosynthetic bacteriab)Halophytesc)Xerophytesd)HydrophytesCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Crassulacean acid metabolism photosynthesis pathway is present as adaptation in xerophytes in which stomata opens during night to prevents loss of water by transpiration.#@

Answer

Since CAM is an adaptation to arid conditions. plants using CAM often display other xerophytic charecters such as thick,reduced leaves with a low surface-area-to-volume ratio,thick cuticle,and stomata sunken into pits,some shed their leaves during the dry season others(the succulents)store in vacuoles.

Answer

Understanding Birth Rate
The birth rate is a crucial demographic indicator that reflects the reproductive health and growth potential of a population.
Definition of Birth Rate
- The birth rate specifically refers to the number of live births in a given year per 1,000 individuals in the population.
- It is often expressed as the birth rate per capita, which gives a clearer picture of population growth relative to its size.
Why Option 'C' is Correct
- Number of Births per Capita: This metric allows for the comparison of birth rates across different populations, regardless of their total size.
- A higher birth rate per capita indicates a higher level of reproduction within the population, which can have implications for future demographic trends, resource allocation, and social services.
Other Options Explained
- Option A: Number of births per individual - This is not a standard demographic measure and does not accurately represent population growth.
- Option B: Number of births per year - While this provides information on total births, it lacks context regarding the population size, making it less useful for comparative analysis.
- Option D: Number of births per square kilometer - This measures population density rather than birth rate and does not convey information on reproductive health.
Conclusion
- Understanding the birth rate as the number of births per capita is essential for demographic studies and public policy, as it provides insights into the population's growth dynamics and socio-economic planning.
