Answer:

The decay of potassium to argon, uranium to lead, and one isotope of lead to another are some common yardsticks used to date very old rocks. These dating methods allow scientists to put real ages on rocks with astonishing accuracy.

Explanation:

The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.

The bacteria which had mutation became resistant to the antibiotic and survived and keeps on increasing, promoting natural selection.

Explanation:

The bacteria rapidly divide, the chances of mutation in the gene increases manifold.

The strains of bacteria causing tuberculosis and staph infection got mutated at DNA level such that they became resistant to antibiotics when tested those susceptible did not survive. These mutations were not harmful to bacteria and the resultant bacteria survived.

These bacteria which survived and proliferated as the environment was in their favour.

Thus, Darwin's Theory of Natural Selection is acceptable here as it says if a mutation is occurring towards the increase in population, they will be selected ones.

We often hear people talk about family traits and how they seem to skip a generation, according to Mendel what has happened?
Vesnalui [34]
This family trait that skips a generation comes from an autosomal recessive trait or as Mendel called as hidden non-dominant trait. Offsprings have a dominant and recessive trait which comes from both parents. Recessive trait appears only when two offspring with same recessive trait blends. This happens in self-fertilization. In the human population, marriage is prohibited between offsprings, thus having recessive trait is only imminent when cousins are married.
