By dating the rocks in the ever-changing crust, as well as neighbors such as the moon and visiting meteorites, scientists have calculated that Earth is 4.54 billion years old, with an error range of 50 million years.

Answer: Fewer harmful mutations are inherited by sexual reproduction than by asexual reproduction.
Explanation:
A germline mutation is the mutation in the germ cells (of the fully developed sperm and ovum) of the parents. When the affected parents undergoes with the sexual reproduction the mutations are passed from the parents to the offsprings. When either the mutated oocyte or mutated sperm meet to form a zygote the precursor of new life. Thus few mutations are inherited by sexual reproduction than by asexual reproduction.
Researchers have identified specific gene variants in the receptors that detect sweetness: TAS1R2 and TAS1R3. There is also high variation in the detection of bitterness. However, the story is more complicated than sweet taste, as we have 25 receptors that detect different bitter molecules
