</span>The glands which get involved are the pancreas and adrenal glands.</span><span> During increase in blood sugar, the pancreas secretes insulin, a hormone produced by the beta cells of the pancreas. Insulin causes red blood cells, muscle cells and fat cell to absorb sugar from the blood.</span><span>During decrease of blood sugar, the pancreas secretes glucagon, a hormone produced by the alpha cells of the pancreas. Glucagon causes the liver to release the glucose stored in its cells.</span><span>The Adrenal gland secretes cortisol during times of low blood sugar levels. Cortisol promotes the use of fatty acids to provide energy for working muscles, rather than using glucose.</span>
Given:
Fixed charges = $40
Variable charges = $1.70 for each mile.
To find:
The equation that represents the total cost y for x miles towed.
Find the y-intercept and interpret its meaning in the context of the situation.
Solution:
Let y be the total cost for x miles.
Fixed charges = $40
Variable charges for 1 mile = $1.70
Variable charges for x mile = $1.70x
Now,
Total changes = Fixed charges + Variable changes
Therefore, the required equation is .
Putting x=0 in the above equation, we get
Therefore, the y-intercept is 40. It means the charges to hook a car is $40 if it is towed 0 miles.
Answer:
The correct answer is option D. A and C.
Explanation:
Lymphoid tissue is the body part that is an essential part of the immune system that provides immune response against different infection or pathogens and protects from these foreign bodies. These tissues are present in all over the body that includes spleen, adenoids, tonsils, lymph nodes and other parts.
Lymphoid tissues or organs are the sites of the proliferation of the macrophages and lymphocytes. These structures also assist in furnishing surveillance points for lymphocytes and macrophages.
Thus, the correct answer is option D. A and C.
