What does the fossil evidence indicate?
A. Mycorrhyzae evolved from the first vasular plants.
B. All major fungal groups had evolved by the end of the Carboniferous.
C. Fungi evolved from protists.
D. The Ascomycota evolved from the Zygomycota.
Why is the classification of protists based on DNA sequences useful? *
a. Because only protists have DNA
b. Because it has confirmed the traditional categories for protists
c. Because it has revealed evolutionary relationships, even among organisms that look diffferent
d. All of the above are correct
This is a required question
(2) Why is a species with small population more likely than one with a large population to undergo an extinction? *
a. Because small population are exposed to greater environmental changes
b. Because genetic diversity is likely to be lower in a small population
c. Because the mutation rate is too low
d. Because they take too long to produce an offspring.
Why is the classification of protists based on DNA sequences considered useful? a. Because only protists have DNA b. Because genetic sequences have confirmed the traditional categories of protists c. Because DNA reveals evolutionary relationships, even among organisms that look different d. All of the above are correct.
