Blue-green algae are better than plants at moving from place to place.

Answers

Answer 1

An organism that is composed of many cells, gets its nutrition from decaying organisms, and has cell walls belongs to kingdom fungi.

What is taxonomy?

Taxonomy is the system of classifying all living things into appropriate groups. The incorrect statement about taxonomy is; "any different orders of organisms belong to the same species."

The kingdom that contains organisms that can survive by photosynthesis or by consuming organic material in dark conditions is fungi.

The difference between mammals and reptile is that the presence of hair in mammals that is not found in reptiles.

An organism that is composed of many cells, gets its nutrition from decaying organisms, and has cell walls belongs to kingdom fungi.

The reason why plants and blue-green algae are classified in different groups is because Blue-green algae use their chlorophyll differently from plants.

Why does a more generalized and flexible feeder (red fox) sometimes have a
competitive advantage over a more specialized feeder like the giant panda?

Answers

A more generalized and flexible feeder (red fox) has several food sources, and a more specialized feeder like the giant panda has a restricted diet.

The red fox is an omnivore?

To be classified as an omnivore, the animal needs to eat both animal foods and plant foods. Most omnivorous animals are “opportunists”, that is, they choose the foods they find most easily.

With this information, we can conclude that opportunistic omnivores tend to adapt more easily to new conditions imposed by the environment.

discuss why prokaryotic cells probably appeared before eukaryotic cells​

Answers

Answer:

Prokaryotes are smaller and less developed compared to eukaryotes. Some of them inhabit very primitive environments that resemble earth’s early stages. Endosymbiotic theory states that eukaryotes arose by the endosymbiosis of prokaryotes.

Explanation

By endosymbiont theory, eukaryotic cells arise from prokaryotic cells. Here, the theory shows that eukaryotic ancestors lived in close association with prokaryotes, wherein in some cases, prokaryotes have been engulfed and might have lived inside eukaryotes.

Upon being engulfed by a host cell as undigested prey, these prokaryotes could have been internal parasites of the eukaryotes. But, later on, their relationship becomes mutualistic and these prokaryotes become incorporated as organelles, such as in the case of chloroplasts and mitochondria, which were previously separate prokaryotes

The rod receptor cells contained in the retina and are useful in low-light conditions.

What are the functions of rod cells?

Rods are cylindrical shaped photoreceptors. They are more numerous than cone cells, with an estimated 92 million rod cells located in the human retina.

Rods are a type of photoreceptor cell in the retina. They are sensitive to light levels and help give us good vision in low light. They are concentrated in the outer areas of the retina and give us peripheral vision.

Rod cell death causes night blindness, but visual disability and blindness result from cone degeneration and therefore it is critical to determine the mechanisms by which it occurs. The death of rods reduces oxygen consumption resulting in high tissue levels of oxygen in the outer retina.
