Answer: They lack nucleus and other organelles important for the synthesis of the enzyme.
Explanation:
The main function of the red blood cells is to supply oxygen throughout the body. The oxygen binds to the hemoglobin and travels throughout the body to ensure the supply of oxygen to various organs and more precisely the cells of the body.
The enzymes that is being synthesized inside the body is produced by the help of the gene and nucleus along with the other organelles involved in it.The mature red blood cells lack nucleus in order to increase the surface area for carrying the oxygen.
As there is no nucleus, mitochondria and golgi apparatus in the cell, there is no enzyme synthesis and broke down in the cell.
Mutations can be categorized based on the kind of effect they have on an organism. Blue eyes in humans are a result of a mutation in the OCA2 gene, which controls the production of pigment melanin in the iris.
This mutation is an example of a neutral mutation. Such mutations have no effect on an organism’s survival.
1) When a star's temperature or size increases, its luminosity increases. In other words it seems more bright.
2) The electromagnetic spectrum is used to determine different types of light waves (infrared, visible light, x-rays etc.) which produced by different kinds of astronomical objects.
