Explanation:
Compounds are those substances that are made up of elements that are combined in a fixed proportion or ratio. The individual property of element is lost once it forms a compound. The physical and chemical properties of both compound and an element is different.
Example of a compound is water and its elements are hydrogen and oxygen. Water is a colorless liquid that acts as a solvent and dissolves most of the solutes in it. While oxygen and hydrogen occurs as gases in their elemental state.

Primary growth or lengthening of plants results from mitotic division in cells of the apical meristem tissue. The apical meristem can be found in the top of plants. When the plant divides, it helps to lengthen it. The correct choice is C.
The answer is C.
The man’s genotype must be AB. The woman’s genotype can be either BB or BO as both correspond to a blood type (which is a phenotype) of B.
Each parent passes on one allele. The man can contribute A or B and the woman can contribute B or O.
The possible genotype combinations are therefore AB, AO, BB, and BO. These correspond to the phenotypes AB, A, B, and B.
Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.
