photoreceptors
olfactory receptors
mechanoreceptors
Answer: olfactory receptors
Sharks have highly developed olfactory receptors. The olfactory receptors in animals allows them to sense the odor. Sharks have olfactory receptors more sensitive than humans. They have nostrils located on the underside of their snout, which they use for smelling not for breathing. The smell of the prey animal or the blood of any animal is detected by the shark with the help of these receptors.
From the calculations, we can see that the length of the arc is 13.3 inches.
The arc is the portion of the circle that is bonded by two radii. Recall that the radius is a line drawn from the center to any part of the circumference.
Arc length = 2πr(C / 360)
Hence;
r = 2 * 3.14 * 8(95/360)
r = 13.3 inches

Gene is basic unit of heredity is found on segments of DNA and are passed on from parent to offspring.
A gene is physical and functional unit of heredity which is made up of DNA.
Genes control both DNA and RNA function.
Some genes codes protein for functional expression of a trait where as some genes do not code for proteins.
In humans, the size of genes ranges from few hundred DNA bases to more than 2 million bases and human have between 20,000 and 25,000 genes.
Each gene have two copies, one is passed from each parent. Only 1 percent of the total genes is slightly different between people.
This is because of presence two different types of allele the same gene which contribute to each person’s unique physical features.

A carcinoma is a type of cancer that develops from epithelial cells, specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells that originate in the endoderm , mesoderm and ectoderm, which are the germ layers during embryogenesis. Carcinomas occur when a cell's DNA is damaged or altered and the cell begins to grow uncontrollably and becomes malignant. It is derived from the Greek, καρκίνωμα, karkinoma, which means pain, ulcer or cancer (derived from karkinos meaning crab).
