Answer:

The correct answer is D.

Explanation:

The Ras Proto-Oncogene is a gene found in normal cells, which by the single point mutation mentioned in the question, can turn into Oncogene. Because Proto-Oncogene is a gene that controls and regulates the division of the cell, a mutation in this gene leads to uncontrolled cell divisions which then leads to cancer. The correct answer is D since RAF-Activation describes "Rapidly Accelerated Fibrosarcoma, fibrosarcoma being a cancer which affects fibrobalst cells.

I hope this answer helps.

Describe what happens to a meal of oily beans and maize from the time of ingestion up to the time of aborption
alexgriva [62]

Food is chewed and mixed by the teeth and tongue before being rolled into boluses by peristalsis and entering the stomach through the cardiac sphincter. In the stomach, gastric juice contains pepsinogen, which is activated to pepsin, which breaks down proteins in beans into shorter peptides. Finally, food is churned and allowed into the duodenum via the pyloric sphincter muscle. Finally, bile Trypsin breaks down proteins into shorter peptides, and pancreatic juice, which is released by the pancreas, contains pancreatic lipase, which breaks down bean oil into fatty acids and glycerol. When food enters the ileum, where succus entericus is secreted, it contains the enzymes maltase, peptidase, and lipase, which break down the remaining lipids (oil) into fatty acids and glycerol, which are then absorbed through the lacteals of the villi. Maltase breaks down maltose into glucose, which is then absorbed.

The Digestion and Absorption Process

Even before you put food in your mouth, digestion starts. Your body notifies your brain that it is time to eat when you feel hungry. Your body's ability to prepare for eating is influenced by sights and odours. Your brain receives a message when you smell food. The mouth is subsequently instructed by the brain to prepare, and you begin to salivate in anticipation of a mouthwatering meal.
