In guinea pigs, black (B) is dominant to grey (b). Long hair (H) is dominant to short hair (h). You have a black, long haired guinea pig. You don't know the genotype so you perform a test cross. You have 3 black and long haired, 3 grey and short haired, 2 black and short haired, and 2 grey and long haired. What is the genotype of your guinea pig?

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.

It's either -limiting factors or -scarce resources but i'd go with my first answer since the food and water are abundant they really aren't scarce
