The process of obtaining a large number of identical copies of a gene or organism is: MCQ with Answer and Explanation

Explanation:
Ammonotelic organisms excrete ammonia directly into water, which dilutes it. This is feasible for fishes. The reason correctly explains why they are ammonotelic.

Explanation:
Water moves from the soil (high water potential) into root hair cells (lower water potential due to solutes) by osmosis across the semipermeable membrane. Active transport is for minerals, transpiration pull is for upward movement.

Explanation:
Chloroplasts are present only in the green, photosynthetic parts of plants, not in root cells or non-green tissues. Plant cells typically have a single, large central vacuole occupying most of the volume, whereas animal cells have small, temporary vacuoles. Centrioles are absent in higher plants (angiosperms and gymnosperms) but present in animal cells and some lower plants. Only statement 2 is correct.
