If scientists wanted to learn about the climate during the time this tree lived, what part of the fossilized wood would they MOST LIKELY examine?
A) the rings
B) the center
C) the underlying bark
D) the outer layer of bark

A the ring

Explanation:

Pieces of fossilized wood can be used to describe the climate change during their lifetime because the rings inside the wood give evidence of the climate changes. The size and color of the rings are results of the climate that the tree lived in. The study of tree rings is called dendrochronology.

it is either c or d and i know for sure it is not a or b

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
