Answer:
Which type(s) of cell division reduce(s) the chromosome number by half?
Meiosis l
Which type(s) of cell division can be classified as reductional?
Meiosis I
Which type(s) of cell division can be classified as equational?
Mitosis and Meiosis II
Explanation:
Meiosis is a type of cell division which occurs in the germ or reproductive cells to produce gametes. It is completed in the two stages, meiosis I and meiosis II. The cells which are going to divide by meiosis are diploid having two sets of chromosomes. Meiosis I is the first stage of the meiosis. At the end of meiosis I two daughter cells are formed having only 1 set of chromosomes and chromosome numbers are reduced to half. Thus, meiosis I is a reductional division.
Mitosis and meiosis II is the equational division as after division chromosome number remains the same as in the parent.
Answer:
Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.
Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.
Fungi. Many skin diseases, such as ringworm and athlete's foot, are caused by fungi. Other types of fungi can infect your lungs or nervous system.
