You should draw these simple Punnett Squares as it's easy to see the answers:
1. Crossing RR x Rr results in all (100%) red cow offspring. 50% will be RR (homozygous dominant), 50% will be Rr (heterozygous).
2. Crossing Rr x Rr results in 3 red offspring (75%) and 1 white (25%). Genotypes though will be 25% RR, 50% Rr, and 25% rr.
3. Crossing rr x rr will result in 100% white offspring. All offspring will be rr.
Three states of matter. solid, liquid, and gas.
solid. water molecules are close together and vibrate, definite size, fixed shape.
liquid.
gas.
The state of matter molecules move the slowest.
The state of matter molecules move the fastest.
Melting.
Boiling.
If a repressor protein attaches to the operator, RNA polymerase cannot proceed to transcribe key enzymes needed by the organism. This can be seen in the trp operon in E .coli bacteria.
