Which type of bacteria live in the roots of legumes?nitrogen-fixing bacteria
pathogenic bacteria
aerobic bacteria
rickettsia

Answers

nitrogen fixing bacteria called rhizobia

Answer:

The correct answer would be nitrogen-fixing bacteria.

Nitrogen-fixing bacteria live in symbiotic relationship in the roots of plants especially leguminous plants such as peanuts, soybean, pulses et cetera.

The symbiotic bacteria live in the root nodules of the plants.

It helps in fixing the atmospheric nitrogen and converts into the forms which can be used by plants.

In return, plants provide the bacteria with shelter and food (glucose).

Example of symbiotic bacteria would be rhizobia

Sickle-cell anemia is a genetically inherited disease. Homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become ill and may die. Individuals homozygous for the sickle-cell trait (ss) have sickled red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the hemoglobin disorder. However, individuals with the heterozygous condition (Ss) have some sickling of red blood cells, but generally not enough to cause death. In addition, the heterozygotes tend to survive better than either of the homozygous conditions as they are resistant to malaria. If 16% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be heterozygous (Ss) for sickle-cell and therefore resistant to malaria?

Answers

Answer:

Explanation:

it depends on the total percentage of the population. that way we can pick out the percentage of the heterozygous

Final answer:

The percentage of the population that will be heterozygous (Ss) for sickle-cell and therefore resistant to malaria is 84%.

Explanation:

To calculate the percentage of the population that will be heterozygous (Ss) for sickle-cell and therefore resistant to malaria, we need to find the frequency of the ss genotype first. Given that 16% of the population is born with a severe form of sickle-cell anemia (ss), the frequency of the ss genotype is 0.16.

Since we are dealing with a single gene with two alleles, the sum of the frequencies of all possible genotypes should equal 1. So, to find the frequency of the Ss genotype, we can subtract the frequency of the ss genotype from 1.

Frequency of Ss = 1 - Frequency of ss = 1 - 0.16 = 0.84.

Finally, to get the percentage, we can multiply the frequency by 100.

Percentage of the population that will be heterozygous (Ss) = Frequency of Ss x 100 = 0.84 x 100 = 84%.
