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.
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
The most common gas in the atmosphere is nitrogen, because it is found in all living things, and as you may know, there are billions of living things here on Earth.

Answer:
10⁴¹ s quark top lives have been in the history of the universe.
Explanation:
You need to determine how many quark top lives there have been in the history of the universe, that is, what is the age of the universe divided by the lifetime of a top quark. Expressed in a formula, this is:
Yo know that the "Age of the universe" is 100,000,000,000,000,000 which can also be expressed as 10¹⁷ s
.
You also know that the "Lifetime of a top quark" is 0.000000000000000000000001 which can also be expressed as 10⁻²⁴ s.
Then 
Recalling that the result of dividing two powers of the same base is another power with the same base where the exponent is the subtraction of the initial exponents, it is possible to calculate this division as follows:
<u><em>t=10⁴¹ s</em></u>
So <u><em>10⁴¹ s quark top lives have been in the history of the universe.</em></u>
Explanation:
Stern et al. (1999) and Stern (2000), define this variable as those general visions about the world, reflected in the beliefs that people express about their relationship with the environment and nature.हेलो फ्रेंड्स मारो किसी को इनबॉक्स कैसे करें
