That is true. Each hemisphere of the brain specializes in assisting various functions of the body.
The vertebrate cerebrum (brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure. The brain can thus be described as being divided into left and right cerebral hemispheres.
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.
Number 3 is microorganisms.
Answer:
The cell membrane is semi-permeable. It allows some molecules to enter easily inside the cell whereas some molecules are blocked from entering the cell.
Small, polar molecules and hydrophobic molecules enter easily through the cell membrane. But large molecules and ions cannot easily move inside the cell membrane.
A hydrophilic substance like the substance L mentioned in the question enters the cell membrane through the help of carrier proteins. The substance attached to the large protein might enter through active or passive diffusion but it can only enter the cell by attaching to carrier proteins.
