Answer:
RrYy is the genotype that is heterozygous for both seed shape and seed color. The traits here we are discussing are pea plant's seed color and shape.
Explanation:
A dihybrid cross is a cross in which two traits are simultaneously being studied. Here there are two traits under consideration that are seed shape and seed color. The seed shape can be round or wrinkled and seed color can be yellow or green. The round seed allele is dominant over yellow seed allele and the yellow color allele is dominant over green color allele.
As homozygous indicate both alleles of a gene are same in an individual and heterozygous condition indicates that both alleles of a gene in an organism are different.
Therefore the genotype of homozygous pea plants for seed color and seed shape can be RRYY or rryy respectively and genotype of heterozygous genotype will be RrYy respectively.

Explanation:
Ice wedging, pressure release, plant root growth, and abrasion can all cause mechanical weathering. in the cracks and pores of rocks, the force of its expansion is strong enough to split the rocks apart. ... This release of pressure causes the rock to expand. As the rock expands, cracks form in it, leading to exfoliation.

(a) Agree
It is probable that less sticklebacks will have pelvic spines in Bear Paw Lake, as it is a smaller region without as much competition. Predators may be much lower in such an environment, eliminating a need for such protection. In the ocean, however, there is much biodiversity and competition, so the fish need pelvic spines to protect themselves.
Appropriately named, <u>slow pain </u>oftentimes is not detected until seconds or even minutes after an injury; this is due to the activation of chemically sensitive pain receptors.
Explanation:
According to physiology of pain, slow pain arises when unmyelinated C fibers of the muscles are activated. This is pronounced as a dull and aching pain and is more diffuse in nature rather than fast pain which are more acute and rapid.
Most of the times this pain will not be detected immediately after the stimulus like an injury but may start slowly.
Slow pain can also be burning, throbbing or even nauseous. Chronic pain conditions mostly are characterized by slow pain.
Slow pain is elicited by stimuli like mechanical, chemical or thermal which are received by the chemically sensitive pain receptors on the skin or other organs of the body.
