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.
Answer:
16
Explanation:
By using the law of independent assortment, you can solve this by calculating

however, crossover can cause endless possibilities of genotypes!
Answer:
49.14%
Explanation:
The frequency of the heterozygous individuals in the population is therefore: 64/400 = 0.32
Using the Hardy Weingburg equation of a population is equilibrium = p2 + 2pq + q2 = 1
q2 = 0.32; Therefore q = 0.5657 –> alellic frequencies
If p + q = 1; Then p 1 – q = 1 – 0.5657 = 0.4343
Heterozygous individuals are represented by 2pq = 2 * 0.4343 * 0.5657 = 0.4914
0.4914 * 100 = 49.14% of the population which translates to 0.4914 * 400 = 196.56 (197) individuals
Answer:
its the maximum amount that can be taken without depleting the resource or population over the long-term.
Explanation:
The doctor who is concerned that wilma may have a brain tumor recommends that a(n) positron emission tomography (PET) scan.
PET scan is a scan imaging test that allow doctor to check disease in human body. This scan uses a special dye that contain a radio active tracer.This scan provide information about blood flow and how body is using oxygen and sugar.
