I would say A- Allosteric Regulation, Competitive Inhibition, and Enzyme-Substrate Complex
Allosteric Regulation- the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site
Competitive Inhibition- a molecule similar to the substrate but unable to be acted on by the enzyme competes with the substrate for the active site
Enzyme-substrate complex- a temporary molecule formed when an enzyme comes into perfect contact with its substrate... when the substrate enters the active site.
(I’m so sorry if that’s wrong)
Answer:
Ecosystem seems to be the right answer NEVER SECOND GUESS YOUR SELF I have done it and it's the worst thing you can do
Answer:
a. My list is the following:
1. presence of photosynthetic pigments
2. presence of cell wall
3. body symmetry pattern
4. presence of cell nucleus
5. presence of specialized organelles
6. presence of hair
7. presence of mammal glands
8. niche (e.g., terrestrial or marine habitats)
9. diet (food habits)
10. position of a particular muscle
Explanation:
b. In the list above, traits such as the presence of a cell nucleus or specialized organelles can be used to classify organisms at the kingdom level (since these phenotypic features are observed in eukaryotic organisms but not in prokaryotes). In a similar mode, animals may exhibit two different body symmetry patterns: radial (around the central axis) and bilateral (two sides: left and right), thereby symmetry body can be used to classify organisms within the animal kingdom. Other features used to classify species at high levels include the presence of photosynthetic pigments in green plants (chlorophyll) and bacteria (xanthophyll), presence of cell walls in plants (composed of cellulose,) and fungi (composed of chitin), presence of hair and mammal glands (mammals), etc. On the other hand, ecological differences (e.g., food habits, niche) and minor anatomical differences (e.g., the position of a particular muscle) are helpful to classify species at the family/genus level.
