<h2>Answer with Explanation </h2>
I have been as of late pondering, on the off chance that I take a sufficiently incredible vitality source (photon) and I have an ideal mirror precisely before it and expect a "producer" shot the light towards the mirror. As impeccable mirrors assimilate no vitality of ANY sort from photons, should this imply the ideal mirrors could never move because of exchange of force of the light? it depends on the mass of the mirror, obviously. Your ideal mirror would have a vast mass, in which case it could assimilate the force change, without engrossing any vitality. A reflection of limited mass will ingest some vitality in a crash that will change the vitality and along these lines the wavelength of the photon. There is no logical inconsistency here.
The correct option is A.
Fitness refers to the quantitative representation of natural and sexual selection within an evolution. Fitness can be defined in respect to a genotype or a phenotype. Relative fitness is described as the survival or reproductive rate of a genotype or phenotype relative to maximum survival or reproductive rate of other genotypes in the population. Thus, the fitness of a population can be determined by finding out the number of offspring that survive to adulthood.
The answer is hox gene.
Hox genes are responsible for an embryo's body plan. They determine different body structures - legs, vertebrae, antennae, wings, depending on groups. Mutation in hox genes is serious mutation since it affects the early stages of embryo and consequently, normal development. If a mutation occurs in the hox gene for legs growth, the legs will not develop.

Answer: The correct answer is- D certain factors are dominant and other factors are recessive.
Mendel was interested in knowing the offspring that is produced from the cross pollination (that is from two different plants) as he wanted to study different traits of pea plant.
For doing so, he first removed the anthers of one plant (to prevent self pollination) and then transferred the pollens of one plant into the stigma of another plant.
When he allowed the cross pollination of purebred pea plant with other plant, he observed that some factors are dominant (such as tall height of pea plant, which masks the expression of recessive factors) and other are recessive (such as dwarf height of pea plant).
Thus, option D) is the right answer.
