Answer:
false
Explanation:
The parathyroid gland refers to the four small endocrine glands located in the neck region behind the thyroid. It secretes the parathyroid hormone or parathormone which regulates the calcium levels in our bodies. It comprises two types of cells which are:
a. The oxyphil cells appear at the onset of puberty and they have no known functions. They appear pink or orange when stained with hematoxylin and eosin stain.
b. The chief cells are more abundant compared to the oxyphil cells and stain dark purple by the action of hematoxylin and eosin stain. Their major function is to produce parathyroid hormone which regulates the amount of calcium in the body.
The given question is incomplete as options are not provided, however the options are as follows :
- Golgi bodies
-lysosomes
-microvilli
-multiple nuclei
Answer:
The correct answer is - golgi bodies.
Explanation:
Goblet cells and glandular epithelial cells are cells that produce and secretes a specific type of products that are termed as the mucin to protect the skin and layer mucous membrane they place.
These cells are characterized by a large amount of Golgi body and endoplasmic reticulum as they are involved in the exocytic pathway which means they secrete, glycoproteins, mucin, and other substances. Golgi bodies needed to modify, synthesis, and secretion.
Thus, the correct answer is - golgi bodies.
Answer:
8A
Explanation:
I= Q/t, where
I= current (A)
Q= charge (C)
t= time (s)
First convert the time from minutes to seconds.
1 minute= 60 seconds
2 minutes= 2×60= 120 seconds
Using the formula,
I= 960÷120
I= 8A
The Arctic Fox lives in the Arctic Tundra (more or less around Alaska, Iceland I think, and other places like that). During the winter, their fur is very thick and solid white (not always SOLID but generally speaking). During the summer and spring, their fur turns brown.
1. Of course, during the winter in those regions, it's going to be snowing and ice is going to be all over the ground. By having a white coat, they're able to blend in and hide from predators, such as the Arctic Wolf and Polar Bears. By turning brown, they'll be able to blend in with the dirt after the snow and ice melts, and again, hide from predators. For the other fox, their brown coat blends in with the dirt, trees, dead leaves, etc. and they'll be able to hide from prey and predators alike.
2. The Arctic Fox also has very thick fur during the winter, which allows it to survive the extreme temperatures. They also dig burrows in the snow for shelter in blizzards. This gives them the ability to survive natural disasters (at least one of them).
I can't think of a third one but these should give you a pretty good idea of how their adaptations help them survive. I really love the Arctic fox so I know quite a bit about them. I really hope this helps you.
<h2>Henrietta Discovery </h2>
Henrietta Swan Leavitt discovered cepheids in 1908 during the investigation of different stars in the clouds. She published it by working more on it in 1912 and died in December 1921. This discovery was so important in the society in which she lived because the cosmologist of America was known for this discovery of Cepheids which is a relationship between period, luminosity and quivering stars which changes in light.
