Answer:
<h2>
Gram staining is a technique used to differentiate between Gram-positive and Gram-negative bacteria.</h2>
Explanation:
Gram stain color the bacteria either red or violet depending on whether they are Gram positive or Gram negative. Gram positive bacteria have thick cell wall containing peptidoglycan compared to Gram negative bacteria which have thin cell wall. Due to this Gram positive bacteria stains purple by crystal violet. So, slide containing <em>S. pyogenes</em> with purple violet indicates that it is a Gram positive bacteria.
Answer;
-Cranial nerves
The cranial nerves serve sensory and motor functions of eye muscles, the nose and tongue, and muscles of mastication.
Explanation;
-Cranial nerves are the nerves that emerge directly from the brain (including the brainstem). In contrast, spinal nerves emerge from segments of the spinal cord. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck.
-Each cranial nerve is paired and is present on both sides. The numbering of the cranial nerves is based on the order in which they emerge from the brain, front to back.
Goblet cells are those secretory cells or unicellular glands, which make and expel mucus can be found in simple columnar and pseudostratified columnar epithelia.
<h3>What are goblet cells? </h3>
They are goblet-shaped cells that have a basal nucleus and a cytoplasm loaded with mucins (the main component of mucus).
<h3>Characteristics of goblet cells</h3>
- It is present in the epithelia of the respiratory and digestive systems.
- Its main function is to secrete mucus, which protects and lubricates the inner surface of simple columnar and pseudostratified columnar epithelia.
Therefore, we can conclude that goblet cells are mucus-secreting cells present in epithelial linings.
