Answer:
Option-B
Explanation:
Color deficiency is a condition caused when the person is not able to distinguish the different colors. Since the person is not able to distinguish different color, therefore, the chromo-receptors which are affected are the cone cells located in the retina which allows us to see different wavelengths.
1. Total color blindness is not a rare disease in animals.
2. Total color blindness in which a person is not able to see any color occurs when all types of cone cells become malfunction or completely absent.
3. The red-green color blindness is more common than the blue-yellow color blindness.
4. The mother is usually not affected as she is the carrier of the gene responsible for the color blindness.
Since all options except Option-2 are incorrect therefore option-2 is the correct answer.
All members of Kingdom Protista are eukaryotes, since their cell(s) possess a nucleus and membrane-bound organelles. Protista species can be distinguished from Kingdom Fungi by the lack of chitin in their cell walls, and from Kingdom Plantae by their sexual reproductive structures.
<h3>What are protists?</h3>
- Protists are simple eukaryotic organisms that are neither plants nor animals or fungi.
- Protists are unicellular in nature but can also be found as a colony of cells.
- Most protists live in water, damp terrestrial environments or even as parasites.
- The primary feature of all protists is that they are eukaryotic organisms.
- Protists exhibit locomotion through cilia and flagella. A few organisms belonging to the kingdom Protista have pseudopodia that help them to move.
- Protista reproduces by asexual means. The sexual method of reproduction is extremely rare and occurs only during times of stress.

Answer:
The correct answer is keystone predator.
Explanation:
In sustaining the composition of an ecological community, a keystone species plays an essential function. In the absence of keystone species, the ecosystem would fail to exist and would become drastically different. A predator is a classic illustration of a predator, which inhibits a specific herbivorous species from eradicating the dominant species of plants. In the non-existence of predators, the herbivorous prey would increase enormously and would clean the entire essential plant species, and thus, drastically change the significance of the ecosystem.
