Answer:
(i) Available in the plant:
Chlorophyll
(ii) Available in the soil:
Water
(iii) Available in the air:
Carbon dioxide
(iv) Available during day:
Light / Light energy
Explanation:
For photosynthesis, your raw materials are chlorophyll (to absorb light energy from the sun), light, carbon dioxide, and water. The products are glucose and oxygen.
Chlorophyll can be found in the leaves of a plant.
Light is from the sun.
Carbon dioxide is taken in from surrounding air.
Water is taken in by the roots, along with mineral salts, before being distributed to other parts of the plant.
During the night, respiration takes place. You can think of it as opposite of photosynthesis. Materials are glucose and oxygen, and products are carbon dioxide and water.
Answer: Parietal cells
Explanation:
Parietal cells secrete hydrochloric acid in the stomach. They are also known as oxyntic cells. They are the epithelial cells which is located in the gastric glands found in the lining of the fundus and cardia of the stomach.
The proton pump blocks the hydrogen ion pump in the parietal cells. These drugs are commonly known by the name of omeprazole.
They block the the H+/K+ ATPase proton pump which inturn inhibits both basal and stimulated secretion of the gastric acid from the cells.
Answer:
Cells that support viral replication are called permissive. Infections of permissive cells are usually productive because infectious progeny virus is produced. Most productive infections are called cytocidal (cytolytic) because they kill the host cell. Infections of nonpermissive cells yield no infectious progeny virus and are called abortive. When the complete repertoire of virus genes necessary for virus replication is not transcribed and translated into functional products the infection is referred to as restrictive. In persistent and in some transforming infections, viral nucleic acid may remain in specific host cells indefinitely; progeny virus may or may not be produced.

The nurse administers cimetidine to a 75-year-old client diagnosed with a Gastric ulcer the nurse should monitor the client for the following adverse reactions Headache, Sleepiness, Confusion, Dizziness, Nausea which contribute for the change in Metal status.
- Cimetidine is a H
Receptor Antagonist. - Gastric partial cells contains receptors for Histamine.
- Histamine is released from the Enterochromaffin cells upon the stimulation from food intake or from Vagus nerve stimulation.
- Thus Histamine released from Enterochromaffin cells binds to H receptors on the parietal cells and increases the secretion of HCl.
- Cimetidine has totally opposite effect and decreases the secretion of HCl from the parietal cells.
- Not only on gastric cells H receptors are also present in CNS where they stimulate brain cells.
- The above point justifies the adverse effects of Cimetidine.
- Patients over the age of 50 or those who are severely ill may experience transient confusion while taking H
blockers, particularly cimetidine.
Hence from these points we can conclude that patients who are above 50 years and receiving Cimetidine medication for gastric ulcer should be monitored for the above mentioned adverse reactions.
