When the only force acting<span> on a falling </span>object<span> is </span>gravity<span>, the </span>object<span> is said to be in free fall. </span>force<span> of </span>gravity<span> is an unbalanced </span>force<span>, which causes an </span>object<span> to accelerate. Near the surface of Earth, the acceleration due to </span>gravity<span> is 9.8 m/s2.</span>
Answer:
In biology, a molecular clock can be described as a method to determine the time for the divergence of species which occurred by the process of evolution.
Explanation:
The mutation rates of different molecules are used in this method. The mutation rates for DNA sequences and amino acid sequences are usually considered. The molecular clock can be used to compare and estimate the splitting of a lineage. For example, by this method, one can interpret when the chimpanzees and humans diverged from each other.

You can't have a carrier with a dominant pedigree because other wise than individual or organism would be afflicted by the gene and render them incapable of being a carrier. A carrier is an individual/organism that has a normal phenotype (meaning it is not afflicted by said gene) but is carrying the gene that could cause disease or whatever the affect may be. In this case the gene would have to be homozygous recessive to be expressed. Hopefully this helps!
