The process of converting food into energy in cells is:
A. Fermentation
B. Photosynthesis
C. Cellular respiration
D. Transpiration
Answer: Option C
Solution (By JKSSB Mock Tests)
Cellular respiration breaks down glucose and other nutrients in the presence of oxygen to produce ATP. Photosynthesis builds glucose, fermentation is anaerobic energy production, transpiration is water loss.
Explanation:
Mendel’s first law (segregation) states that the two alleles for a trait separate during gamete formation. Homozygous individuals have identical alleles; phenotype is observable trait; a monohybrid ratio is 3:1.
Explanation:
Taq polymerase is a thermostable DNA polymerase enzyme isolated from the thermophilic bacterium Thermus aquaticus, found in hot springs. It is used in the Polymerase Chain Reaction (PCR) because it can withstand the high temperatures (around 94°C) required for the denaturation step of PCR without being destroyed, unlike normal DNA polymerases.
Explanation:
The four pulmonary veins drain oxygen-rich blood from the lungs into the left atrium. The pulmonary artery carries deoxygenated blood from right ventricle to lungs. Vena cava brings deoxygenated blood to right atrium.
