Answer:
Phosphorous has the smallest atomic size.
Explanation:
As we know these elements belong to same period means there valence shell is the same. So moving from left to right along the period the shell number remains constant but the number of protons and electrons increases. So, due to increase in number of protons the nuclear charge increases hence attracts the valence electrons more effectively resulting in the decrease of atomic size.
Elements and their atomic radius are as follow,

Explanation:
Well the rocks can be thrown around or just start breaking down. Sorry if I'm not correct
The plants of this ecosystem were influenced by the change of abiotic factors (climate).
The plants who had these specialized structures that have helped them conserve water and adapt to these new environmental conditions were more successful, and left more offspring.After several generations, the specialized plants became more prevalent.
Since there was a selection of successful individuals trough generations, we can conclude that this was due to the working of the evolutionary mechanism called the natural selection.
Answer:
if chemistry hadn't been put up to practical use, we wouldn't truly understand the reason why humans are humans like makes up humans (including other understandings of biology, etc) and we wouldn't be able to have the advancements we have today (vaccines, etc).
