A. Without natural predators, the species may outcompete native species
(1) All the genotypes are as follows: AABB, AaBB, AABb, AaBb, aaBB, aaBb, AAbb, Aabb, aabb.
(2) Assuming that Aa is dominant and Bb is recessive, there will be 9 phenotypes with both A and B allele dominant (i.e. AaBb, AABb); there will be 3 phenotypes with just the A allele dominant (i.e. Aabb, AAbb); there will be 3 phenotypes with just the B allele dominant (i.e. aaBb, aaBB); and there will be 1 phenotype with both alleles recessive (i.e. aabb). The phenotypic ratio in this case is 9:3:3:1.
(3) The probability of producing an offspring with the aabb genotype is 1/16 or 6%.
Correct answer: A) Extension
Extension is a physical position that occurs when angle between the bones and the limbs of joint increases.
It takes place when there is a contraction of muscles and bones move the joint from a bent to a straight position, it is opposite of flexion, in which the angle between the bones and the limb at the joint decreases.
Example: During straightening of the leg, the angle between the tibia and femur increases, which shows extension has taken place.
Answer:
The prey population, the rabbits, and the predator population, the foxes, directly rely on one another. As the rabbit population grows, more food becomes available for the fox population to grow, therefore the fox population grows. The rabbit population now has more predators, but an assumed constant amount of food, causing the rabbit population to fall. The rabbit population falls and less food becomes available for the fox population, so the fox population falls. Both the predator and prey species are majorly responsible for the carrying capacities of the other species.
