The hormone that regulates the basal metabolic rate is: MCQ with Answer and Explanation

Explanation:
The Wobble hypothesis, proposed by Francis Crick, explains the degeneracy of the genetic code. It states that the base pairing rules (A-U, G-C) are strictly followed for the first two bases of the mRNA codon, but the third base of the codon (the 3' end) can form non-standard or 'wobble' base pairs with the first base of the tRNA anticodon (the 5' end). This allows a single tRNA molecule to recognize and bind to more than one synonymous codon.

Explanation:
Gastrin is a peptide hormone produced by the G cells (gastrin cells) located in the pyloric antrum of the stomach. Its primary function is to stimulate the parietal cells of the gastric glands to secrete hydrochloric acid (HCl) and the chief cells to secrete pepsinogen. This prepares the stomach for the digestion of food. Gastrin also stimulates gastric motility and growth of the gastric mucosa. Secretin and CCK stimulate the pancreas and gall bladder.

Explanation:
Bacillus thuringiensis (Bt) is widely used as a biopesticide, specifically a bioinsecticide. The spores of Bt contain crystalline proteins (Cry toxins) that are toxic to the larvae of many insects, particularly Lepidoptera (caterpillars), Diptera (flies), and Coleoptera (beetles). When sprayed on crops or ingested by transgenic plants, these toxins kill the pests without harming humans, animals, or beneficial insects.
