Some examples of physical evidence that supports scientific theories that earth has evolved over geologic time are the studies have have been done supporting the idea of Pangaea that all the continents were together and with time separated, if you look at a map you can see that the continents almost fits like a puzzle, of course they do not because of erosion and climate change, but it’s the closest example.
Answer:
Soil erotion is like a sloping of land that causes land slides because there are no trees or grasses there to hold the soil together.
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
Energy is the ability to do work. The form of energy that living things need for these processes is chemical energy, and it comes from food. Autotrophs make their own food. Heterotrophs obtain food by eating other organisms. Organisms mainly use the molecules glucose and ATP for energy.
