Answer 2

Eukaryota, Prokaryota and Archaea

Question 3

Explain what is meant by molecular phylogeny

Answer 3

An evolutionary tree measuring the differences between two species in: DNA, mRNA and proteins

Question 4

Explain how molecular phylogeny enables organisms to be classified and evolutionary relationships to be identified

Answer 4

It allows DNA sequences to be predated decades ago enabling taxonomists to highlight relationships due to similar sequences and allows them to classify an organism to smilies one’s depending on their DNA similarities

Question 5

What is meant by the term ‘peer review’?

Answer 5

Where scientists or the same field and quality read peers work with the goal of ensuring academic scientific quality

Question 6

Explain how peer review enables the validity of findings to be established

Answer 6

Peers if the same scientific field and quality can challenge or approve the work. Therefore information can be adapted until scientifically correct

Question 7

List how scientists can communicate their findings to the general public and to the scientific community

Answer 7
