frutty [35]

Answer:

Explanation:

Directional selection is a type of natural selection that occurs when members of a population of a species with a particular extreme phenotype is selected or favored against the other phenotypes when natural forces act on the population of a species. Individuals having the particular traits that are favored survive and become more common that others with traits that are less favored.

Directional selection may likely result in the species of butterflies in which darkly collared butterflies are not preyed upon, ensuring their survival, while the other butterflies with other colors will be phased out with time. Darkly colored butterfly will be selected for while the others will be selected against.

Complete the flowchart to identify the process by which blue-light photoreceptors and auxin control phototropism in plants.

DaniilM [7]

In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis. This occurs when a seed initially situated in an environment of complete darkness is exposed to light. A brief exposure to electromagnetic radiation, particularly that whose wavelength is within the red and far-red lights, results in the activation of the photorecepter phytochrome within the seed. This in turn sends a signal through the signal transduction pathway into the nucleus, and triggers hundreds of genes responsible for growth and development

The whale's flipper and tail flukes and fish fins are analogous structure as they have different structural formation but they perform the same function.

Flipper and tails are locomotory organs in the whale and helps the whale in propelling similarly fins in the fish assist the fish in swimming. Both the strcutures have evolved differently and are made of different materials.

Why are protozoa significant? Select all that apply. Protozoa contaminate the water supply. Protozoa do not contribute to a food

Luba_88 [7]

Answer: Protozoa contaminate the water supply.

Some protozoa are parasites and cause diseases like malaria.

Protozoa have an important role in the food chain.

Protozoa are parasitic or free living single celled eukaryotic organisms. They are mostly found in water bodies.

Protozoa contaminate the water supply: Some of the protozoan species which are released from the human feces usually contaminate thee water, and causes waterborne infections in humans. Examples are Cryptosporium and Giardia. The infection occurs through drinking water or swallowing water from swimming pool.

Some protozoa are parasites and cause diseases like malaria: The Plasmodium is the genus belonging to the protozoan parasites. This malarial parasite is transmitted by female Anopheles mosquitoes to humans. The parasite multiply in the red blood cells causes symptoms like fever, anemia, flue, illness and may also cause coma and death.

Protozoa have an important role in the food chain: The protozoa species plays many roles in the food chain, they act as consumers, predators or prey, herbivores and decomposers. Their main function is to control the population of other species in the same habitat. They engulf small single celled bacteria, hence prevents excessive bacterial colonization act as predator. They also feed upon the algal species therefore, act as herbivores. They act as decomposers, as they feed upon the organic matter present in the bottom of the aquatic water body. They are the source of food for large worm and insect species.
