c) alpha enzymes
d) Hydrolases
4. As per geological times scale, hormids evolved during:
a) Miocene
b) Pliocene
c) Pleistocene
d) Oligocene
5. The four elements that make up 99% of all elements found in a living system are:

Answers and Explanation:
1. – b) The sunlight is absorbed by chlorophyll pigment. In the excited state, chlorophyll expels its energy along with all electron and a positive charge comes on the chlorophyll molecules.
2. – c) Nucleolus is known as ribosomal factory because in eukaryotes the ribosomal RNA synthesized in the nucleolus or outside the nucleolus but ribosomal protein synthesized in the cytoplasm
3.- d) Hydrolytic enzyme secreted by lysosomes, active at low pH called hydrolases.
4.- b) Pliocene
