2-Has been found to destroy the roots and leaves of many forests.

3-Can erode buildings and monuments

THIS PHOTO SHOWS AS THE FIRST PHOTO HOW THE ACID RAIN IS FORM BUT ALSO THE CONSEQUENCES IT HAVE

Mendel inheritance

Mendel discovered that when crossing white flower and purple flower plants, the result is not a blend. Rather than being a mix of the two, the offspring was purple flowered. He then conceived the idea of heredity units, which he called “factors”, one of which is a recessive characteristic and the other dominant.

1-The Law of Segregation states that when any individual produces gametes, the copies of a gene separate so that each gamete receives only one copy. A gamete will receive one allele or the other.

2-The Law of Independent Assortment, also known as “Inheritance Law” states that alleles of different genes assort independently of one another during gamete formation.
