Answer and Explanation:
Hybridization results when varieties of organisms with different characteristics are crossed. The resulting offspring often show characteristics which are superior to either of the parents and are said to possess hybrid vigour. Artificial breeding is done either by inbreeding or cross breeding. Plant and animal breeding involves selectively choosing and breeding those plants and animals with desirable qualities.
Answer:
The ray which strikes at the normal is called incident ray and the ray which bounce back after striking the surface is called reflected ray

Answer:
If blue flower colour is dominant to white then there will be two conditions for the dominant plant. It will either have homozygous dominant (BB) alleles or it will have heterozygous alleles (Bb). The phenotype will be blue flower colour.
As the white flower is recessive,it will have the alleles bb. The phenotype will be white flower colour.
If all the offsprings produced by the cross are blue, then it means that the dominant blue plant was homozygous for the trait. All the offsprings produced will have blue colour and a heterozygous genotype.
Answer:
Organisms have different proportions of bases in the DNA.
Explanation:
Option B is correct because different organisms have different proportions of bases in their DNA. This makes each species unique. This means that it is not possible for multiple species of have similar proportion of DNA bases.
Other options are incorrect because of following reasons:
1. All the genetic information cannot be universal among all organisms. Different species performs different functions and the genetic information differs accordingly.
2. All animals cannot have similar amount of bases in their DNA. Different animals have different bases.
3. The given table doesn't say that plants are least related. In fact, all organisms differs in terms of DNA bases proportion.
Answer:
A macromolecule is a very large molecule, such as protein, commonly created by the polymerization of smaller subunits (monomers). ... The most common macromolecules in biochemistry are biopolymers (nucleic acids, proteins, carbohydrates and lipids) and large non-polymeric molecules (such as lipids and macrocycles).
