Question

1. according to paragraph 7, we know that the phylogeny system-

a. groups organisms together into units called clades.
b. has phylogenetic or evolutionary trees and cladograms that demonstrate the same
pattern.
c. traces the relatedness of organisms according to their evolutionary history.
d. all of the above

1. what is the main aim of the study of systematics?

a. to calculate how many organisms there are on earth
b. to understand the evolutionary relationship of biological organisms
c. to create a naming system for biological organisms
d. none of the above

1. what do you call the system that categorizes organisms by using a naming system that

includes the genus and species?
a. dichotomous tree
b. phylogeny
c. cladistics
d. binomial nomenclature

Explanation:

Question 1

To solve this, we analyze each option:

• Option A: Phylogeny systems do group organisms into clades.
• Option B: Phylogenetic trees and cladograms can show the same evolutionary pattern.
• Option C: Phylogeny traces organism relatedness via evolutionary history.

Since all A, B, C are correct, D is the answer.

Systematics is about understanding the evolutionary relationships between biological organisms. Option A is incorrect (it's not about counting organisms). Option C is about taxonomy (naming), not systematics. So B is correct.

Binomial nomenclature is the system that names organisms using genus and species (e.g., Homo sapiens). A dichotomous tree is for identification, phylogeny is about evolutionary history, and cladistics is about clades. So D is correct.

Answer:

D. All of the above
