Explanation: The main difference between Genetic and Hereditary Diseases is that genetic disease is a condition which occurs due to an abnormality in the individual’s genome while a hereditary disease is a condition caused by a mutation of a gene which can be characteristically transmitted from one generation to another, also The main difference between these two terms lies in the fact that hereditary diseases have the potential of being carried from one generation to another whereas a genetic disease can either be hereditary or not, but there will always be a mutational change in the genome.
Answer:
CaCO3+2HCl=CaCl2+H2O+CO2 this is the balanced reaction occur between calcium carbonate and HCl to minimize the hyperacidity.
Explanation:
CaCO3 reacts with hydrochloric acid produced by oxytonic cells of the stomach to generate calcium chloride (CaCl2) and water(H2O) along with the release of carbon dioxide(CO2) gas.
This reaction helps to minimize hyperacidity.
White light is made up of all colors of the rainbow, so it could reflect Red, Orange, Yellow, Green, Blue, Indigo, and Violet.
The light that is reflected is the color that we see because it reflects into our eyes.
Since we see that the paper is red, the red light is being reflected which causes us to see red.
