There would be less variability in the genes of the watermelon plants and is denoted as option A.
<h3>What is Variability?</h3>
This is defined as the difference between organisms which is caused by genetic or environmental factors.
Using the seeds from the largest, tastiest watermelons will reduce variability over time because these characteristics will become dominant.

Answer:
Cooperative. (Ans. B)
Explanation:
Cooperative interaction is also called as mutualistic interaction. It is defined as an interaction where One that benefits the recipient other than the performing the behavior.
So, in this study a layer of purple photosynthetic bacteria is using sulfide as an electron source. Sulfide is oxidized by these bacteria, which grow in a layer above sediment from which you have isolated sulfate-reducing bacteria that generate sulfide during anaerobic respiration.
These bacteria's are showing cooperative interaction between each other. Where one species producing a product (sulfate reducing bacteria) that serves as food for other species (photosynthetic bacteria).
Answer:
as people use more and more fossil fuels for their purposes they are not distributed evenly
These lines (there is four of them) are residuals of the fusion of the five sacrum vertebrae that are fused. These "vertebrae" or segments present a characteristics, being the first of them very similar to a lumbar vertebra, large, and the other vertebrae are<span> progressively smaller and flattened. They also present a curved shape being anteriorly concave.</span>
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.
