Answer:

Changes that occur in species, over a long period of time and that include the the replacement of unfavorable characteristics by helpful variations lead to evolution (second option).

Explanation:

Evolution, in terms of biology, consists of the genetic, anatomical and functional changes that occur in individuals of different species, acquiring useful characteristics that replace unfavorable characteristics, due to processes such as natural selection, proposed by Charles Darwin.

Biological evolution raises the existence of a common ancestor, from which all current known species are known, and an evolutionary line for each of those species. Evolution is considered the basis of biodiversity, due to the genetic changes it has produced over many years.

Answer:

Approximately 20,500 genes

Explanation:

The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.
