Which of the following organisms is included in the Kingdom Monera? MCQ with Answer and Explanation

Explanation:
The urinary bladder is a muscular sac that temporarily stores urine received from the kidneys via the ureters, until micturition. The urethra drains urine to the exterior.

Explanation:
Restriction enzymes (restriction endonucleases) are molecular 'scissors' that cut DNA at specific, highly specific recognition sequences (palindromic sequences). They are essential tools in genetic engineering for cutting both the source DNA (gene of interest) and the vector DNA at specific sites, creating compatible ends for ligation. DNA ligase is used to join the fragments.

Explanation:
Eutrophication is the excessive enrichment of water bodies with nutrients (primarily nitrates and phosphates from fertilizers and sewage). This leads to rapid growth of algae, known as an algal bloom. When the algae die, their decomposition by bacteria consumes large amounts of dissolved oxygen, leading to hypoxia (low oxygen levels) or anoxia, causing the death of fish and other aquatic organisms.
