What are point mutations? What are frameshift mutations? Which are worse?

A point mutation is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a DNA or RNA sequence of an organism's genome.

A frameshift mutation is a genetic mutation caused by indels of a number of nucleotides in a DNA sequence that is not divisible by three

frameshift mutation are worse... . ... frameshift mutation results from an insertion or deletion of a number of nucleotides that is not a multiple of three..but point mutation affect a single base pair

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
