Mendel crossed two plants that were heterozygous for purple flower color. which genotypes could he have used to represent the cross? pp ´ pp pp ´ pp pp ´ pp pp ´ pp

The answer is Pp Pp.

If we imagine that plant has two alleles for the trait and if P represents dominant allele, and p represents recessive allele, then genotypes are:
PP - dominant homozygous, which contains both dominant alleles
pp - recessive homozygous, which contains both recessive alleles
Pp - heterozygous, which contains both dominant and recessive alleles

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.
