Answer:
20 feet blood vessels and 1000 nerve endings
Explanation:
The skin is the largest organ of the body and is composed of three layers that are epidermis, dermis and the subcutaneous layer. The outer layer is the epidermis consisting of cells that are tightly packed in around in 20 layers. The middle thick layer is the dermis that consist of glands, nerves, blood vessels, and hair follicles that provide skin its functions. The inner layer is the subcutaneous that is composed of connective tissue and fat.
The square inch of skin consist of 20 feet blood vessels, 1000 nerve endings, 650 sweat glands and 100 oil glands. The blood vessels supplies blood to the tissues and the nerve endings upon stimulation sends signals to the brain and generate response depending on the kind of stimulus like heat, pressure, pain, or temperature.
Answer: B. Alleles.
A variant form of any given gene is an allele. One of the two alternative forms of any particular gene which is present at the same locus of the chromosome is an allele.
Different forms of an allele determine the phenotypic traits. Most of the multicellular organisms are diploid having two sets of chromosomes, each inherited from one parent. If both the alleles of any gene are same on the particular position of chromosome then it is termed as homozygous and if the alleles of the gene are different, it is called heterozygous.

- Adrenal gland
- Thyroid gland
- Parathyroid gland
