The process by which bacteria take up free DNA from the environment is: MCQ with Answer and Explanation

Explanation:
Antidiuretic Hormone (ADH), also known as vasopressin, is released by the posterior pituitary in response to osmotic pressure or fluid loss. It acts primarily on the collecting ducts of the nephrons to increase water reabsorption by making them more permeable to water. This prevents diuresis (excessive urine production) and helps conserve body water.

Explanation:
Gymnosperms are seed-producing plants where the ovules are not enclosed in an ovary; hence, the seeds are naked. They are predominantly perennial, evergreen, woody trees like pines and cedars. Double fertilization and the formation of triploid endosperm are unique characteristics of angiosperms, not gymnosperms. Thus, statements 1 and 2 are correct.

Explanation:
Transformation is the uptake of free DNA from the surroundings and its incorporation into the bacterial genome. Conjugation requires cell-to-cell contact via pilus, transduction involves bacteriophage, translation is protein synthesis.
