The alleles bb for black hair and ll for long hair are part of that cat’s a. phenotype b. genotype c. linkage map d. allele

The alleles BB for black hair and LL for long hair are part of that cat's genotype. Genotype is the genetic make up of a cell, and therefore it determines characteristics of an organisms (phenotype).  It is the genotype that determines the the hereditary potentials and limitations of an individual from embryonic formation through adulthood. 

B. genotype, is the correct answer

Crossing over creates new combinations of genes in the gametes that are not found in either parent contributing to genetic diversity

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.
