The correct answer is B. a fossilized fish
That is because the scientist can use carbon dating to find the age of the fish, and that will tell the scientest the date of the layer of rock. :)
<span>Anthropology is a science which studies human study of both in terms of culture, behavior, diversity, and so forth. Anthropology is a term word comes from the Greek word anthropos and logos. Anthropos meaning human and logos means story or word.

The correct answer would be a physical change
1) Body tube (Head): The body tube connects the eyepiece to the objective lenses. Arm: The arm connects the body tube to the base of the microscope. Coarse adjustment: Brings the specimen into general focus. Fine adjustment: Fine tunes the focus and increases the detail of the specimen.
2)Microscopes are made up of lenses for magnification, each with their own magnification powers. Depending on the type of lens, it will magnify the specimen according to its focal strength.
3)In simple magnification, light from an object passes through a biconvex lens and is bent (refracted) towards your eye. ... The eyepiece lens usually magnifies 10x, and a typical objective lens magnifies 40x. (Microscopes usually come with a set of objective lenses that can be interchanged to vary the magnification.)
Surface area<span> of a solid object is a measure of the total </span>area<span> that is occupied by the surface of object.
If two objects has same mass, then smaller size particles will have greater surface area.
Thus, in order to increase the surface area of ice, one can crush it into small particles. Due to crushing, particles will break into smaller size and eventually this will result in larger surface area. </span>
