Answer:
A. Group A only
Explanation:
The experimental group was group A, on the other hand, the control group was group B.
An experimental group is a set of people that receives treatment in an experiment, supplement daily in this case.
In every experiment, there is a test of subjects that are exposed to the treatment that is being studied called experimental group. But also, they must perform the same experiment with another test of subjects not exposed to the new treatment called control. In other to see if they are any differences between the two of them.
In this case, the treatment supplement daily was given to the group A. And the placebo or sugar pill with nothing in it was given to the group B to compare and confirm if the treatment actually works.
Cross pollination through wind and other animals and self pollination through the flowers themselves.
Answer:
Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time.

Mitochondria. The “powerhouses” of the cell, mitochondria are oval-shaped organelles found in most eukaryotic cells. As the site of cellular respiration, mitochondria serve to transform molecules such as glucose into an energy molecule known as ATP (adenosine triphosphate).
