Answer:
Phenotype ratio= 12 colorless : 3 purple : 1 red
Genotype ratio= 1:2:1:2:4:2:1:2:1
Explanation:
According to the given information, the dominant allele "I" is epistatic to P and p alleles and presence of "I" inhibits the expression of both "P" and "p" alleles.
A cross between two heterozygous plants for both locus would give the F2 progeny in 12 colorless: 3 purple: 1 red ratio.
Here, the F2 genotype with "I-G" and "I-gg" would produce colorless kernels while the ones with "ii-G-" would exhibit purple colored kernels. The F2 genotype "iigg" would beak red kernels.
Hence, the phenotype ratio= 12 colorless : 3 purple : 1 red
Genotype ratio would be same as for the mendelian dihybrid cross= 1 IIPP: 2 IIPp :1 IIpp: 2 IiPP :4 IiPp: 2 Iipp: 1 iiPP :2 iiPp: 1 iipp
"The origin of a muscle is attached to the bone that does NOT move" is true among the following statements.
The origin and insertion of an attachment are the points of attachment. When a muscle contracts, the point of attachment known as the origin remains stationary. As a result, when contraction occurs, the origin bone is the more immobile of the two bones at the joint.
Skeletal muscles have two or more points of attachment to bone, or occasionally to other muscles or tissues. The attachment is said to as having an origin if the location is a bone that is stationary during an action. The attachment is referred to be an insertion if the location is on the bone that moves during the motion.
The triceps brachii has four places of attachment: three origins and one insertion on the ulna (two on the humerus and one on the scapula).

Answer:
C. The high-tide zone is outside the range of tolerance for Semibalanus.
Explanation:
Semibalanus can out-compete Chthamalus by crowding or smothering, but Chthamalus can occupy higher tide levels than Semibalanus because it is more resistant to desiccation.
The fundamental niche of Chthamalus includes both the upper and middle intertidal zones. - The realized niche of a species is a subset of the fundamental niche, limited by biotic interactions such as competition. The realized niche of Chthamalus is the upper intertidal zone only.
Answer:Global warming increases, there might be heavy rain and storms leading to flood as most of the oxygen released by plant is no more, finally there might be rise in heat wave
