Let’s Start the Quiz!
1. ASSERTION : Shrinkage of the protoplast of a cell occurs under the influence of hypertonic solution. REASON : Hypertonic solution causes exosmosis.
2. ASSERTION : Cellular endosperm is formed by nuclear division accompanied with wall formation. REASON : Cellular endosperm lacks haustoria.
3. ASSERTION : Triangular shaped age pyramid represents a growing or expanding population. REASON : Proportion of individuals in reproductive and post reproductive age group is higher than the individual in pre-reproductive age group.
4. ASSERTION : Natural selection is the outcome of differences in survival and reproduction among individuals that show variation in one or more traits. REASON : Adaptive forms of a given trait tend to become more common; less adaptive ones become less common or disappear.
5. ASSERTION : Replication and transcription occur in the nucleus but translation occurs in the cytoplasm. REASON : mRNA is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.
6. ASSERTION : In vasectomy, a small part of the vas deferens is removed or tied up. REASON : In tubectomy, a small part of the Fallopian tube is removed or tied up.
7. ASSERTION : Diabetes insipidus is marked by excessive urination and too much thirst of water. REASON : Anti-diuretic hormone (ADH) is secreted by the posterior lobe of pituitary gland.
8. ASSERTION : The portion of the myofibril between two successive Z-lines is considered as the functional unit of contraction called sarcomere. REASON : During contraction, I-bands get reduced whereas A-bands retain the length, thereby causing shortening of the sarcomere.
9. ASSERTION : Nephrons are of two types cortical and juxtamedullary according to their relative position in the cortex. REASON : Juxtamedullary nephrons have short loop of Henle while cortical nephrons have long loop of Henle.
10. ASSERTION : Pulmonary circulation consists of flow of deoxygenated blood from right ventricle to the lungs and flow of oxygenated blood from lungs to the left atrium. REASON : Systemic circulation consists of flow of oxygenated blood from the left ventricle to all parts of the body and deoxygenated blood from different parts to right atrium.
