• This was a time before the Industrial Revolution, when textile production was largely a domestic activity, and many people made their own clothing and other textiles at home.

Explanation

• When DNA is transcribed into RNA, the base Thymine (T) is replaced by Uracil (U).
• So, the RNA sequence corresponding to the DNA sequence TAGC would be AUCG.

Explanation

• Rennin (also known as Chymosin) is an enzyme produced in the stomach of ruminant mammals, such as cows, and is also present in the gastric juice of humans.
• It helps to coagulate milk by converting casein, a milk protein, into a gel-like substance, causing the milk to curdle.

• This narrow pH range is tightly regulated by the body's acid-base homeostasis mechanisms to ensure proper functioning of various physiological processes.

Explanation

• Erythrocytes produce energy through glycolysis, which yields lactate as an end product.
• This lactate is normally transported out of the cell and into the bloodstream, but under certain conditions, it can accumulate in the cell.
• Microorganisms like bacteria and yeast, when growing under anaerobic conditions, also produce lactate as a byproduct of their metabolic processes, such as fermentation.
