Answer:
The primary function of mucus in the stomach is <u>protect the stomach cells from gastric juices (e.g., HCl).</u>
Explanation:
The stomach is an important organ in the process of digestion, it performs a variety of functions that include the storage and exposure of food to the acid it secretes, in addition to providing a barrier that prevents the passage of microorganisms to the intestine. The gastric mucosa protects the stomach from digestion caused by acid gastric juices in which the superficial cells of the mucosa would produce a mucous layer, which would leave the stomach completely unprotected. The stomach creates gastric acids to break down food. These acids, also called gastric juices, are very strong acids found in the stomach. Its function is to promote the digestion of proteins that come from the products we eat. The components of gastric juices are produced by the gastric glands found in small cavities of the gastric mucosa. The gastric glands are elongated and consist of several types of cells: superficial cells, main cells and parietal cells. Superficial cells produce mucus that protects the stomach from attack by digestive acids and enzymes.
Answer: perpendicular
Explanation: Joint can be found in areas of the body where two or more bones are connected together, practical examples in the human body can be traced to our elbow, wrist, hip, knee. At Each of these points mentioned, it could be observed that it serves as a meeting point for two or more bones which are linked and formed around an axis. This joints enables us to conveniently move, twist our rigid bones in different directions perpendicular to the plane (that is in a direction opposite or away from the direction of the plane).
Independent variable in a investigation is the factor you control and change (e.g. in plant biology it could be light intensity, a concentration level of substances in added water or soil) that influence the dependent variable (in plant biology this would be the rate of photosynthesis).
There must be a number of groups to prove the influence of the independent variable on the dependent variable and trials to increase credibility of the results. Remember to include a control group where independent variable is not changed. (e.g. in measurement of light intensity on the rate of photosynthesis there must be a control where the light intensity is not manipulated to present the regular rate).
No because there are different types of cells and they have different processes.
cells, tissues, organs, organ systems
The function of an organ system depends on the integrated activity of its organs
