The role a of a digestive system is
Your digestive system breaks down the food you eat into nutrients such as carbohydrates, fats and proteins. They can then be absorbed into your bloodstream so your body can use them for energy, growth and repair.
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.
Answer:
offsprings have identical genes. It's called asexual reproduction.
1. rapid cooling of basaltic lava
2. divergent plate boundaries on them mid ocean ridge system
