Answer:
<em>The correct option is A) 6 years</em>
Explanation:
In ecological studies, carrying capacity can be described as the maximum number of organisms of a species that a particular area can hold.
Each area has certain amounts of resources to carry a specific number of individuals of a species. Beyond this capacity, resources begin to deplete and the organisms start fighting for the resources. As a result, their population declines.
The following graph shows that the forest habitat reached the carrying capacity for rats in the year 6 after which its population began to decline, instead of increasing.
Ans.
Genetic engineering involves manipulation of genetic material organisms to develop organisms with desirable characteristics. Natural selection involves selection of traits that make organisms better adapted to their surrounding environment, without human interference.
Both of the mechanisms involve transmission of genetic information form one generation to another as manipulated genetic material of parent organism is transmitted to next generation.
Both genetic engineering and natural selection select the traits that are most organisms with most beneficial to their environment.
Genetic engineering is faster than the process of natural selection. Natural selection is natural process and it works over generations, while genetic engineering involves desired modification of traits.
Both genetic engineering and natural selection work on all organisms, including humans.
Natural selection involves selection of individuals with beneficial traits for survival, while other individuals with less useful characteristics are wiped out. Therefore, natural selection does not work on entire population.
Thus, the options 1), 3), and 4) are correct.
