Due to the fact that, these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
It carries oxygen to the rest of the body. It can also remove carbon dioxide.
The skeletal system does not digest. That is the job of the digestive system. Hope this helps!
Answer:

Explanation:
Given that,
The mass of a sample, m = 16.7 grams
Volume of the sample, V = 4.4 cm³
We need to find the density of the metal sample.
Density = mass/volume
Substituting all the values,

So, the density of the metal sample is
.
Answer:
We have to evolve or we will just slowly die off.
