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

Show the following as a food chain: omnivore, autotroph, herbivore
Thepotemich [5.8K]

omnivore⇒herbivore⇒autotroph

this is because an autotroph makes its own food (photosynthesis) so it doesn't have the need to eat other organisms. Herbivores eat only plans (remember this with the word herb is a type of plant) and an omnivore will eat either meat or plants so it can eat either of the things below it.
