Answer:
The hard structure like dino bones, teeth and shells are the examples of body fossils.
Option: A
<u>Explanation: </u>
The body fossils are common type of fossils found in the world. <em>These body fossils are formed by the remains of the ‘dead animals and plants’.</em> The body fossils are <em>hard parts of the dino teeth, bones, shells, woody trunks, branches, and stems.</em> The body fossils are formed in different ways and they are the remains of <em>the body parts of ancient animals, plants and other life forms.</em>
<em>They are rarely found in connected nature and are like large vertebrates like dinosaur bones, skulls and teeth’s.
</em> The body fossils are also formed in different ways they are formed like a plants or animals dies in a watery environment and they can be buried in mud or silt they cannot decompose.
They build the top and hardens into the rocks at over time sedimentation. Two types of tissues are decomposed, they are soft and hard tissues.in the decomposition of there leaving hard bones, shells and teeth’s are behind and soft tissues are quickly decomposes.
Option B makes best sense, correct me if i’m wrong
The scientists that study the forces and shape of the earth is called geologist.
The weight of a person increase when the elevator is going up.
<h3>
Weight of the person in the elevator</h3>
The weight of the person in the elevator is calculated as follows;
<h3>When the person is going up</h3>
F = ma + mg
F = m(a + g)
where;
- a is acceleration of the person
- g is acceleration due to gravity
<h3>When the person is going down</h3>
F = mg - ma
F = m(g - a)
Thus, the weight of a person increase when the elevator is going up.
