How many atoms are in a 70 kg human?
topjm [15]

Answer:

7 followed by 27 zeros

Explanation:

The body of an adult man weighing 70 kg is made up of approximately 6.7 • 10 ^ 27 atoms.

The body of an adult male contains approximately 57% water, but if we look by weight, hydrogen is only 11%, while if we look at the mutual ratio of atoms in water, there are a total of 67% hydrogen atoms.

In this way, most of the weight (mass) of the human body comes from oxygen, but most of the atoms in the body are hydrogen.

What can you say about the environments of these widely seperated layers
Alika [10]

Answer:

This means that the two separate rocks were once part of one piece of rock. These layers got separated most probably by continental drift as a result of tectonic plate movements. An example of such a fossil is the Mesosaurus, a freshwater crocodile-like reptile, that is found in Southern Africa and Eastern South America continents- that means they were once one land mass.

The environment in these two separate layers would most likely be different. As the layers drift apart from each other , they drift across latitudes that are determinants of climate in a region. Therefore, even the organisms in these two rock layers will evolve differently (even though they will share a common ancestor) in adaptation to respective environments – this is called allopatric speciation.
