Explanation:
The kidneys regulate blood pressure via the renin-angiotensin-aldosterone system and by controlling fluid volume. The nephron's glomerulus filters blood plasma into Bowman's capsule. Humans are ureotelic, meaning the primary nitrogenous waste excreted is urea, not ammonia (which is highly toxic and excreted by aquatic animals). Thus, statements 1 and 3 are correct.

Explanation:
Pollination is the mechanism of transferring pollen grains from the anther to the stigma of a flower. After fertilization, the ovule develops into a seed and the ovary into a fruit. Double fertilization, involving syngamy and triple fusion, is a unique characteristic of angiosperms, not gymnosperms. Therefore, statements 1 and 3 are correct.
