<span>This is true. Extension is the opposite of flexion, they're like antonyms, so hyperextension would be an extension even beyond that, or in this case, it would be in the opposite direction of the flexion of a joint. That is why the answer to this question should be true.</span>

Question: A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?
a) Incomplete dominance
b) Genetic recombination
c) Chimerism
d) Codominance
Answer:
d) codominance
Explanation:
Codominance is a pattern of inheritance when none of the alleles of a gene is able to mask the expression of the other allele of the same gene. When the two alleles are present together in a heterozygous genotype, both are expressed and the phenotype of the heterozygote is different from both the pure breeding parents. In the given example, cross-pollination of yellow corn and white corn results in the ears of corn that have an approximately even mix of yellow and white kernels. This means that the heterozygote expresses both the allele for the corn color. Therefore, it represents codominance.
Hemostasis is the process by which bleeding is stopped, that is, a process by which the blood is kept back in the broken blood vessel. It is the first stage in the wound healing process.
During hemostasis, three rapid steps occur simultaneously. In the first step, the blood vessel constrict in order to reduce the quantity of blood that is flowing out, secondly, platelets stick together in order to form a temporary seal which covers the break and thirdly blood clottings formed by adding fibrin threads which serves as molecular glue on the surface of the wound.
