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:
1. Newton believed that gravity was a force.
3. The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Explanation:
Law of gravitation states that force is directly proportional to masses of objects and inversely proportional to the distance between from their center. Directly means if mass increases, force of attraction also increased while inversely means if distance decrease between objects, force of attraction is also increased. Gravity is measured in weight because weight ia a force which attracts things towards its center.
The answer is C. They move into an ecosystem :)
A team of students is performing an experiment to determine how the speed of a reaction between HCl and Na2CO3 changes with temperature. The aspect of the experiment that does not have to be kept constant would be the initial concentrations of the reactants. Hope this helps. Have a nice day.
