Organism A has blunt teeth, while organism B has sharp ones. Identify the organisms on basis of their feed habit and give anothe
VikaD [51]

Answer:

- Organism A is most likely a herbivore

- Organism B is most likey a carnivore

Explanation:

Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores.

- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B.

Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE.

- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on.

Impacts of fracking include
nasty-shy [4]

Answer:

D is the answer

Explanation:

Hydraulic facturing, aka fracking, uses toxic chemicals above some regulations which may lead to a leak into water supplies and therefore contaminate it.

It has not much to do with coal, more to do with oil and natural gases

Because of fracking now making it accessible to reach sources in vast number that were previously unacessible, it leads to decreases in gas prices

Hope this helps :)
