1 .medulla oblongata is responsible for controlling autonomic functions of the body and also relays nerve signals between brain and spinal cord.hence Injury to medulla oblongata results to death.
2 .gametes have haploid number of chromosomes because they are formed after meiosis. At the time of sexual reproduction the gametes fuse to form zygote thereby maintaining the actual number of chromosomes.
3. .Broad - maximizes area for light absorption.
Thin - minimizes internal distances for maximum diffusion of CO2,water
NICOTINAMIDE ADENINE DINUCLEOTIDE PHOSPHATE-- NADP
BACILLUS - CALMETTE - GUERIN --BCG
