They ALL have DNA made of the same basic components, but the way that it's organized is different (circular in prokaryotes, linear in eukaryotes, typically). Prokaryotes and eukaryotes have different ribosomes and eukaryotes have membrane bound organelles.
Let's play devil's advocate just for fun. ;-)
1) neither of them are a concern. Even if humans overpopulate the earth, the strong will find a way to survive and Darwin's theory of evolution will determine who deserves to pass on their genes and rule the world. This will result in stronger and stronger humans each generation. Economic wealth is not a concern for similar reasons. The strongest, smartest humans will pass on their genes and their wealth, thus ensuring that only strong, smart humans will survive.
2) People who own the land should decide what to do with it. If there is a disagreement, they can fight about it, and call all their relatives to come back them up in a fight. Whoever survives the fight gets to make the rules.
3)Sustainable develpment strategies are not necessary, becauase God has a plan. We can continue to burn oil, deplete the ozone, and drive giant SUVs because God will provide for us, and then eventually he will take those to heaven who deserve it and let the rest wallow in their hellish filth. >:-)
This is a fun question. Since it's an opinion, it can't be wrong, right? LOL
Increase in air pollution: public transport
decrease in trees: plant new trees
loss of bird habitat: nesting boxes
endangered aquatic species: regulate recreational activities
The answer is *C. is a slow, gradual change over time*.
The correct answer is D, white blood cells.
We know that red blood cells deliver nutrients and are not apart of the immune system; platelets are responsible for coagulation, which has nothing to do with the immune system, and plasma is a substance that, again, has nothing to do with immunity. White blood cells are the only things that fight disease (antibodies are white blood cells)!
I hope I helped!
(By nothing I meant very little to none).
