The species ursus arctos. ursus mantimus, and ursus americanus are all members of the same genus. the classification of the three species
supports which statement about them?
a. members of all three species live in similar environments
b. members of all three species have similar size, shape and body color,
c. the three species share many characteristics and are biologically related
d
the three species are identical, but their members live in different environments.

The correct option is C) The three species share many characteristics and are biologically related.

Explanation:

A genus can be described as the rank in biological system of classification which stands just above the rank of species. The organisms belonging to the same genus are more closely related to one another than to the organisms of the upper rank. Organisms is a genus show many shared characteristics and are biologically related to one another. Hence, we can say that the species Ursus arctos, Ursus mantimus and Ursus americanus are all members of the same genus share many characteristics and are biologically related to one another.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

actually the answer is c
