Who proposed the Cell Theory? MCQ with Answer and Explanation

Explanation:
The common garden pea is scientifically named Pisum sativum. It belongs to the family Fabaceae. Mendel chose this plant for his genetic experiments because it has easily distinguishable contrasting traits, a short generation time, and is primarily self-pollinating. Cicer arietinum is chickpea, and Phaseolus vulgaris is the common bean.

Explanation:
Most bacteria possess a single circular double-stranded DNA molecule located in the nucleoid region. Some bacteria may also have linear chromosomes or multiple chromosomes, but the typical prokaryotic chromosome is circular. Eukaryotes have linear chromosomes. Plasmids are small, circular extra-chromosomal DNA in bacteria.

Explanation:
The Glycemic Index (GI) is a numerical scale (from 0 to 100) that measures how quickly a carbohydrate-containing food raises blood glucose levels compared to a reference food (usually pure glucose or white bread). Foods with a high GI (like white bread, sugary drinks) cause a rapid spike in blood sugar, while low GI foods (like whole grains, legumes) cause a slower, more gradual rise. It does not measure total carbohydrate amount.
