The vaccine for tuberculosis is known as: MCQ with Answer and Explanation

Explanation:
Fertilization in humans typically occurs in the fallopian tube (ampullary region), not the uterus; the zygote then travels to the uterus for implantation. The placenta is the vital organ providing oxygen and nutrients to the growing fetus and removing waste. Spermatogenesis, the production of sperm, occurs in the seminiferous tubules of the testes. Thus, statements 2 and 3 are correct.

Explanation:
Root hairs, unicellular extensions of epidermal cells in the root maturation zone, greatly increase surface area for water and mineral absorption from the soil. Water enters by osmosis. Leaves absorb some water through stomata but primarily lose water. The stem transports, and flowers are reproductive.

Explanation:
Glomerular filtration rate (GFR) is the volume of filtrate formed per minute by both kidneys, normally about 125 mL/min (180 L/day). Nearly 99% of the filtrate is reabsorbed, leaving about 1-2 liters of urine per day. GFR is regulated by the juxtaglomerular apparatus. It's an important clinical indicator of kidney function, estimated from serum creatinine.
