Which of these correctly distinguishes mitosis from meiosis? a) mitosis occurs in germ cells and meiosis occurs in somatic cells. b) crossing over takes place in mitosis and not in meiotic cell division. c) meiosis produces four 2n daughter cells; mitosis produces two 2n daughter cells. eliminate d) the number of chromosomes remains the same in mitosis and is reduced by half in meiosis.

Couldn't the answer be D?

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
