Answer:
In Meiosis, cells are divided twice to the give haploid cells ( four cells) with half the number of chromosomes in the original cell, while in mitosis, cells only divide once to give identical cell with the same number of chromosomes as its origin.
Explanation:
Meiosis is a process where a cell divides to give four cells, with the chromosomes half of that of the original cell. This cell division helps produce your genital cells like sperm and female egg. There are nine stages in meiosis.
Mitosis is a process of cell division where a single cell divides just once to produce two identical cells with the same number of chromosomes as the original cell.
For example, the ABO system of blood groups is controlled by three alleles, only two of which are present in an individual.
Answer:
The ability of an organism to mantain a stable internal enviorment while living in a changing external enviorment.
<span>This classification system model was based on principles developed by Swedish scientist Carolus Linnaeus, whose hierarchical system groups organisms based on common physical characteristics. Taxonomy is a hierarchical system for classifying and identifying organisms. Carolus Linnaeus developed those principles in the 18th century. In 1990, Three-domain system was developed by Carl Woese, an American microbiologist and physicist. The three-domain system divides cellular life forms into archaea, bacteria, and eukaryote domains and each domain can be further divided into kingdoms, phyla, classes, and so forth so it changes every year...</span>

Love Canal. In 1978, Love Canal situated close Niagara Falls in upstate New York, was a pleasant small average workers enclave with many houses and a school. It coincidentally sat on 21,000 tons of lethal modern waste that had been covered underground during the 1940s and '50s by a neighborhood company.
The waterway families didn't realize that they were being presented to harmful synthetic substances, nor were they mindful that concoction squanders were being dumped in our streams, soil, and air. Love Canal stirred a network to the disagreeableness and appalling acknowledgment of how lethal squanders influence our lives, and pulverize our condition.
