Red and yellow bell pepper plant can reproduce with each other - Genetic diversity.
A park has 80 species of trees - species diversity.
There are many breeds of dogs - genetic diversity.
Five different bird species are at a bird feeder - species diversity.
Directional selection favors one of the extreme phenotypes. Option B). Fewer plants with thin seed coats will be able to germinate, leading to a higher proportion of plants that produce seeds with thick seed coats.
<h3>What is directional selection?</h3>
Directional selection increases in the proportion of individuals with an extreme phenotypic trait.
There must be a selective pressure or environmental pressure acting on populations to lead the species to increase the number of individuals expressing that extreme phenotype.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example the environmental pressure is drought during several years.
Drought periods decreases the fitness of plants that produce thin seed coats because they dehydrate before germinating.
Originally the population expressed both types of seeds. But after the drought pressure, only plants that produce seeds with thicker coats got to survive and reproduce.
The correct option is B). Fewer plants with thin seed coats will be able to germinate, leading to a higher proportion of plants that produce seeds with thick seed coats.

Answer:
Option (D).
Explanation:
Dolly was the first sheep cloned in the year 1997. The sheep has been cloned from the adult somatic cells. The sheep was cloned by Keith Campbell, Ian Wilmut.
The adult's cell nucleus was fused with the enucleated sheep egg. The egg was then incubated in the surrogate female. The telomeres of Dolly sheep was found to be shorter than the normal individuals.
Thus, the correct answer is option (D).
The correct answer is the option B) It does not allow for the accumulation of glycogen and, therefore, limits the organism's mobility.
Explanation:
In cellulose and chitin the arrangement of glycogen in in alternate arrangement that provides the support to the plants that makes it strong and the limits its mobility.
If plants lac their special arrangement of the glycogen in chitin and cellulose the water will flow in and it will not be stand upright.
Thus, the correct answer is option B) It does not allow for the accumulation of glycogen and, therefore, limits the organism's mobility.
I believe 6CO2 is the answer
