2. Enzyme is not consumed in the reactio

3. Non-Competitive inhibitors change the Km but Vmax remains the same 

4. Michaelis-Menten kinetics assumes that the amount of Substrate is much lower than the amount of enzyme. 

5. Xylem tissues carry sugars and other nutrients from leaves to all parts of the plant 

6. Mitochondrial RNA (mRNA) changes much more quickly than nuclear DNA.

 7. Three domains of life are bacteria, archaea and protists 

8. Carbonic acid is a buffer 

9. Hydrochloric acid is not a buffer 10. Domain→Kingdom→Phylum→ Order→Family →Class→Genus→Species

12. Tall trees are vascular plants 

13. Mixotrophs can harvest sunlight for photosynthesis and also use any sugars in the environment for their growth.

15. Total concentrations of [H+ ] and [OH- ] are equal regardless of the pH for pure water. 

16. The function of the ancestral gene is maintained for paralogous genes but variations arise after the species divergence. 

17. In the Logistic growth model, the parameter r refers to the carrying capacity of the ecosystem 

18. A selection pressures on weeds in a freshly tilled agricultural field are called r-selection. 

19. Closest protist relatives of plants are red/green algae. 

20. Cis-trans isomers are mirror images of each other. 

21. Invertebrates are the most diverse animal species
