Answer: Option D.
Gastroesophageal reflux disease.
Explanation:
When a person stomach is removed by an operation called gastrectomy . The surgeon connects the oesophagus, a tube that runs from the throat to the stomach to the small intestine. When this happen , there will be acid reflux i.e acid flows back into the oesophagus and causes irritation of the food pipe or oesophagus, this is called Gastroesophageal reflux disease. This occur because there is no stomach where food will undergo some digestive process but in this case the food flows to the small intestine directly and can result in acid reflux
The symptoms of these are heartburn, chest pain, difficult in swallowing food, lump sensation in the throat e.t.c
Iii. ii. Plants need five things in order to grow: sunlight, proper temperature, moisture, air, and nutrients. These five things are provided by the natural or artificial environments where the plants live. If any of these elements are missing they can limit plant growth.
Answer:
Plasmolysis occurs when a <u>plant </u>cell is inmersed in a <u>3X salt solution</u>.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
- <em>Plamolysis does not occur in </em><u><em>animal cells</em></u><em>.
</em>
- <u><em>Pure water </em></u><em>does not produce plasmolysis.</em>
