Answer:
Common examples of ectoparasites include fleas, head lice and bed bugs.
Explanation:
Answer:
species richness is the number of species in an ecosystem
Answer:
7 % progeny will show wild type phenotype
Explanation:
Parent 1: Normal wings and small eyes : DDee
Parent 2 : Downward wings and normal eyes : ddEE
DDee X ddEE = DdEe ( All have normal wings and normal eyes )
When a F1 individual is test crossed:
DdEe X ddee =
De/de = Parental
dE/de = Parental
DE/de = Recombinant
de/de = Recombinant
Recombination frequency between the two genes is 14% hence DE/de and de/de will each have 7% frequency. Since DE/de ( DdEe ) will give wild type phenotype, it means that 7% progeny will have wild type phenotype.
The specific adaptation of the sloths to their niche is energy conservation: they survive by trying not to loose any energy and trying not to move too much. They have less muscle because they don't need it: their adaptation is to move less. So the correct answer is to a) conserve energy.
