How does the rapid reproduction in bacteria cause them to evolve quickly?

Rapid reproduction in bacteria leads to rapid mutations and thereby they cause evolution to occur.

Explanation:

Bacteria are the organisms that can reproduce as early as 20 mins in this universe, when every organism reproduces it does make small changes in the genetic make up so as to survive through the evolution.

Thus when a bacteria reproduces in 20 mins in about 1 hours nearly 2 positive mutations happen thereby causing them to evolve quickly . This is the major reason for antibiotic resistance to build up.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
