Sophie [7]

Answer:

a. eukaryotes

b. unicellular

c. autotrophs; heterotrophs

Explanation:

Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.

The frequency of sickle-cell anemia, an autosomal recessive condition, is 0.007. Assuming that the population is in H-W equilibr
damaskus [11]

Answer:

The correct answer is - 0.084

Explanation:

Sickle cell anemia is a autsmal recessive blood disorder of RBCs where RBC shape altered to the sickle shape or cresecent moon that obstruct and damage the veins and artries.

Normal allele is represented by - HbA - p

sickel cell allele is represented by - HbS - q

genotype frequency of normal allele HbA in the population = p2

genptype frequency of HbAHbS in the population = 2pq

genotype frequency of autosomal recessive HbS = q2 = 0.007 (given)

So, the allelic frequency of the recessive allele =

q =  √ 0.007 = 0.08366 or 0.084
