Answer:
The correct answer will be option-B (Semi-synthetic)
Explanation:
Chemical drugs can be synthesized through many ways on the basis of which they can be categorized:
1. Natural Drug: The drug prepared from the natural extracts.
2. Synthetic Drug: The drug is synthesized by chemical reactions.
3. <u>Semi-synthetic Drug</u>: The drug which is neither completely natural nor synthetic that is they are prepared from the natural extracts by modifying them.
Since in the given question, the drug was prepared by the converting side chain to the hydroxyl group of the antimicrobial drug therefore it is considered as the semi-synthetic drug and Option-B is the correct answer.
Answer:
Evolution
Explanation:
Natural selection is usually defined as a process by which an organism or a specific type of living species adapts to a new environment in order to grow, develop, reproduce and protect themselves from the predators. During this time of migration, evolutionary changes occur in organisms over a specific period of time. It occurs naturally and there are several factors that affect these changes occurring in an organism.
Evolution simply refers to the growth, development, and expansion of an organism that occurs over a definite time period.
Answer:
Because volvox can photosynthesise
Explanation:
Volvox is a multicellular algae. They grow in spherical colonies.
Its cells contain chloroplasts meaning it can photosynthesise. This means it can use light energy from the sun to synthesise its own food. Therefore, it doesn't need to capture food from the environment.
It is a Chemical reaction taking place un a solution in which one or more of the products is insoluble in the solvent, and so forms solid particles that fall to the bottom of the reactor
