Please answer question 1 and question 2

Chapter 5 Question 1 0.8 / 1 point Fungi fulfill an important ecological role as saprotrophs_, of organisms that also make nutrients available in almost all ecosystems. Out of the 1.5 million estimated species, all100000_described species of fungi are actually more closely related to animals_than_plants , or decomposers of dead organic matter Saccharomyces cerevisiae are the other major group Question 2 0.5 1 point A molecular phylogeny starts with an alignment of homologous genes. In other words, genes that share a common ancestor. Eachsitein a gene sequence is a character and the identity of the nucleotide there is the character state. Sequences that differ from the ancestral state are the result of speciation that happened after the species diverged. When two sequences share one of these mismatches, it indicates recent mutations

Explanation / Answer

1. fungi are saprophytes because they are heterotrophs.

saccharomyces cerevisiae is the correct

all the remaining options you filled and the blanks are correct.

2.

each nucleotides in a gene sequence is a character.

identity of site is the character of the state.

sequences that differs from the ancestral organisms are due to variation not speciation.

Indicates mutation of change in the DNA.
