Answer:
246 K
Explanation:
6.850 mL=6.85 L
PV=nRT
T=PV/nR
T= (2.21 atm* 6.85 L)/(0.750 mol * 0.0821)
T=246 K
Answer:
Natural Selection.
Explanation:
This process is an example of natural selection. You may know it as "survival of the fittest." This means that the organisms with the best traits for surviving will survive, while the others will unfortunately die off.

Vertebrate include fish, amphibians, reptiles, birds and mammals. Invertebrates include worms and jellyfish, spiders and crabs.
<u>common characteristics among vertebrates and invertebrates </u>
○ multi-cellular.
○ heterotrophs (cannot make their own food) and must get their energy by consuming plants or other animals.
○ obtain food and oxygen for energy,
