Question

timothy uses a written dichotomous key of paleozoic fossils to identify the type of organism a fossilized shell found on a walking trail came from. what will he most likely find as he gets closer to identifying the shell? (1 point) the dichotomous key will be simple and easy to follow. the dichotomous key will have arrows to help him follow along. the dichotomous key will have more general characteristics. the dichotomous key will have more specific characteristics.

Explanation:

A dichotomous key is used for identification by presenting a series of paired statements (characteristics) that narrow down the identification. As one progresses in identifying an organism, the characteristics become more specific to distinguish between closely related groups. So, as Timothy gets closer to identifying the shell, the dichotomous key will have more specific characteristics. The other options are incorrect: the key isn't necessarily simple/easy at the end, arrows aren't a defining feature of progression, and general characteristics are at the start, not as one gets closer to identification.

Answer:

The dichotomous key will have more specific characteristics.
