Which of the following statements about evolution is correct? MCQ with Answer and Explanation

Explanation:
The glomerulus is a tuft of capillaries enclosed by the Bowman's capsule, where ultrafiltration occurs due to high hydrostatic pressure in the afferent arteriole. It filters water, ions, glucose, amino acids, urea into Bowman's space. Proteins and cells are retained. Filtration is passive. The filtrate then passes through the tubules for processing. GFR is regulated by JGA.

Explanation:
Ciliated pseudostratified columnar epithelium (with goblet cells) lines the trachea and bronchi; the cilia beat in coordinated waves to move mucus and trapped particles out of the airways. Squamous epithelium is flat (alveoli), cuboidal in kidney tubules, transitional in urinary bladder.

Explanation:
Fertilization typically occurs in the ampulla, the widest region of the fallopian tube, where the sperm meets the secondary oocyte. The zygote then travels to the uterus for implantation. The ovary releases the egg, the uterus supports embryo development, the cervix is the lower portion opening into the vagina.
