2.Location
Scientist use fossils to study body structures and compare them.
Scientist use location to study location to see how organisms used their features to cross water or survive in different temperatures.
Answer:
❥ Ripe pawpaws give off a wonderful fruity aroma. If the pawpaw does change color, it will likely turn a lighter shade of green, possibly with some yellowing. A more reliable indicator is feeling. The fruit will begin to feel softer, much as a peach or avocado.

The three major clades of bilaterian animals are the <span>ecdysozoa, lophotrochozoa, and deiterstomia.
Ecdysozoa are organisms that include insects, crustaceans, chelicerata, and myriapods. Lophoytochozoa include fossil organisms. Deiterstomia include chordata, echinodermata, and hemichordata.

<span>Compound Microscope
Compound microscope is commonly used in the schools and colleges.
It comes under the category of microscopes used in biology.
It has two lenses namely the objective lens and the ocular lens.
It provides a magnification of 1500X.
Eyepiece lens is of 10X or 15X power.
It is used to observe bacterial, protozoa, various cells, etc.
</span><span>Dissecting Microscope
It is also called stereo microscope.
Its magnification power is less than the other microscope.
It gives a 3 dimensional picture.
Due to the low magnifying power they are used to observe little bigger objects than other microscopes.
They are used in the surgeries, dissection, forensic science etc.</span>
