All living organisms are made of only 20 different aminoacids- this is the correct answer! This means that the genetic code only codes for those 20 aminoacids (for example Glutamine and  Lysine). 
The 20 aminoacids that can form proteins are also called Proteinogenic amino acids.

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.

Biological classifications have changed over the years. What is probably NOT a reason for these changes?
katrin2010 [14]

Scientists change the names of taxonomic groups to match the current nomenclature is probably NOT a reason for these changes.

Scientists change the names of taxonomic groups to match current nomenclature.

<u>Explanation:</u>

There are various main reasons why taxonomists from time to time require or choose, to modify the name of an organism such as a plant. Initially, the naming of plants is treated by a set of laws ( the International Code of Botanical Nomenclature ) which sets out how to accurately name plants and how to solve cases where two or more names have been used for one species.

It seldom happens that applying the rules requires us to change a name. For example, if a species named by one botanist turns out to have been before legitimately named by an elder botanist.
