Answer 20

yes, because of necrotic tissue

Question 21

Know how to correctly use the binomial naming system devised by Carolus Linneaus.

Answer 21

genus name is capitalized and species name is lower case.

Also both need to be in italics or underlined

Question 22

How can the scientific name be abbreviated?

Answer 22

you take the first letter of the genus name and add a period, and then have the full name of the species name, Still needs to be in italics or underlined
