Scientists collect information that allows them to make evolutionary connections between organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.

Answer:
b. making an observation and asking a question
Explanation:
In scientific method there need to be a situation to be study. In this description, the scientist first observed that in a certain region there is some kind of trees and the other variable is the great amount of deer.
After making different observations, and some research of other areas similar to the one that is study, she is asking what is the relation among the animals and the trees.
The next step will be to formulate a hypothesis using all the data and the two variables that she observed.
The answer is <span>c. Cold and flu season occurs when the weather is cold, so there must be a connection.
Even though choices a. and b. could make sense, nothing in Joel's research implies the connection between the choices and cold. Therefore, this leaves choice c. as the right one. If cold and flu season occurs</span><span> when the weather is cold, there must be a connection between cold and cold weather.</span>
