Question 1 • Life Science Q1

Why would a scientist want to identify this species of spider? Check all that apply.

Answer
A
to be certain that it is a spider
B
to compare it to similar spiders
C
to determine the relationship it has with other organisms
D
to determine if the spider is safe to handle or not
E
to find out how many offspring it has had this year

Explanation

Identifying a spider species lets a scientist compare it with similar spiders and understand its relationship to other organisms. It can also help determine whether the spider is safe to handle, since some species are venomous or otherwise risky. Identification is not needed just to confirm that it is a spider, and it does not reveal how many offspring it has had this year.
