Answer:
Potential energy is energy that has not been used
In exponential growth, the growth rate of population per capita remains the same in spite of the size of the population, thus, resulting in the population to grow faster and faster as it gets bigger. However, in nature, the populations may grow exponentially for certain time duration, and they eventually get restricted due to limited availability of resources.
In the graph, it is evident that from 1950 to 1990 there is exponential growth, signifying that the fish exhibited almost optimal conditions of living. However, in 1990 the population started to decline steadily, demonstrating an extreme lack of resources or enhancement in predatory species.
Natural selection is one of the basic mechanisms of evolution during which those variations in the genotype that increase organism's chances of survival and procreation are preserved and multiplied from generation to generation at the expense of those that are less advantageous. In this case the following are postulates of natural selection; Individuals with certain traits are more likely to survive and reproduce, individuals in a population vary more likely to survive and reproduce, survival and reproductive success are variable among individuals in a population and lastly some traits differences are heritable.
The answer is: insert the gene responsible for larger sized kernels into the genome of the corn with smaller sized kernels and a high yield.<span>
The techniques of genetic engineering are used to introduce hybrid genes for some desired substance or trait into the genome of other organisms. Here, the desired trait is larger sized kernels. So, the gene responsible for this trait will be inserted into the genome of the corn </span><span>with smaller sized kernels and a high yield.
It should be taken into consideration why two other choices are not correct:
1. there are no genes for less or more of something in the genome.
2. genes are part of a genome, so the genome for a trait cannot be inserted into a gene of an organism.</span>
