The dominant trait is hornless.
If this is correct, then the original bull is a heterozygote:
H = hornless
h = horned
Bull is Hh
Cross 1: Hh x hh (horned female) - offspring is hh (horned)
Cross 2: Hh x Hh (hornless female) - offspring is hh (horned)
Cross 3: Hh x hh (horned female) - offspring is Hh (hornless)
Cross 3 is the key to confirming this because the only way to get a hornless offspring would be if hornless is recessive.
There is misspelled. It should be spelled their
Lysosomes remove waste at a cellular level.
They contain digestive enzymes, so they're like the digestive system.
The stomach digests food, so lysosomes could be considered like the stomach.
But then again, so do the intestines, small and large.
Since the stomach doesn't also work to remove waste though, I'd say the answer is probably large intestine, which finishes the digestive process and removes waste material.
Answer:

or just mass.
The Law of Universal Gravitation states that the force of gravity acts between all objects in the universe that have mass.
