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.

Explanation:
Mitochondria are cell organelles that are found in all human body cells except mature red blood cells. These organelles with a double membrane are the location in which cellular respiration occurs.

Answer:
C
Explanation:
Over time the pond accumulates nutrients. This enrichment process is called eutrophication. The addition of nutrients stimulates the growth of aquatic life. These organisms live and grow and die
The conclusion supported by the data is that as yeast produces more carbon dioxide, it releases less sugar into the environment.
<h3>How do yeasts work in fermentation?</h3>
Through fermentation, yeasts break down the glucose molecule to produce energy for your cell. In this process, carbon dioxide and alcohol are formed, favoring the production of products such as bread and alcoholic beverages.
Whit this information, we can conclude that the conclusion supported by the data is that as yeast produces more carbon dioxide, it releases less sugar into the environment.
