Biology
Gregor mendel discovered that tall was dominant and short was recessive in pea plants.when he crossed two plants that were both heterozygous tall (tt) he found a 3: 1 ratio of tall to short (75% tall, 25% short) in the offspring leading him to conclude that in a monohybrid cross, the offspring would show a 3: 1 ratio of dominant to recessive phenotypes.a student in a biology lab wants to know if plant flower color is also determined by simple mendelian genetics.first she crosses a true breeding white flowering plant with a true breeding red flowering plant and observes that the offspring all produce red flowers.she then crosses two of these red flowering plants and records the phenotypes of the offspring

The third law of motion states that for every action, there is an equal and opposite reaction. This can be observed both in objects at rest and those that are accelerating. For example, a resting box pushes down on the ground due to a gravitational force.
