Answer #1

Mitosis is known as equational division and it occur in diploid somatic cells of animals.But plants show mitosis both in haploid and diploid cells.For growth of an organism mitosis is essential.

To study mitosis in animals scientists use whitefish embryo.Embryo cells are rapidly dividing cells.Therefore we can easily study mitosis in embryo cells like blastula.

For studying mitosis in plants we can use meristematic cells.Growth in plants is largely restricted to meristems.Apical meristem of onion root can be used for such a study.

    In 2012, Psychologist Heather Butler studied the importance that critical thinking plays in our everyday lives. "Critical thinking is not just the new buzzword in education. Critical thinking involves real outcomes that can be measured, predicted, and—perhaps for the negative life events—avoided" (Butler, 2012, p. 725). In 2013, studies by Grossmann, Varnum, Kitayama, and Nisbett concluded that wise reasoning, rather than intelligence, was a predictor of well-being. In 2017, Dr. Butler and her colleagues, referencing the Grossmann study and based...
