Answer:
Bones consist of living cells embedded in a mineralized organic matrix. This matrix consists of organic components, mainly type I collagen – "organic" referring to materials produced as a result of the human body – and inorganic components, primarily hydroxyapatite and other salts of calcium and phosphate.

The Cornea
Explanation:
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.
Answer:
The correct answer is option D. Osmosis
Explanation:
Osmosis the process in which high solute concentration molecule move to low concentration molecule through the semi-permeable membrane.
In the hypotonic solution, a cell get lysed due to solute movement into the cell whereas in a hypertonic solution cell shrink due to movement of solute out of the cell.
Thus, the correct answer is option D. Osmosis.
An allelle is the alternative form of genes that contribute to human genetic variation.
Explanation:
Any change in the DNA sequencing which leads to the difference between individuals is called genetic variation.
A trait is the characteristic feature which is passed on from one generation to another.
Different forms of traits expressed by different individuals are characterized by genes present in the DNA. The variant or alternative form of genes which leads to such genetic variation is called an allele. This produces the characteristic differences among humans.
Alleles are found in pairs and can either be recessive or dominant depending upon the genotypes (heterozygous or homozygous).
Characteristics like color of the eye or hair, the height of an individual, length or shape of the nose, and various other specific characteristics are expressed by these alleles
