Answer:
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-2))
m=2/(0+2)
m=2/2
m=1 ==> Gradient of graph
x-int: (-2, 0)
y-int: (0, 2)
Explanation:
m=(y2-y1)/(x2-x1)
m=(2-0)/(0-(-2))
m=2/(0+2)
m=2/2
m=1 ==> Gradient of graph
x-int: (-2, 0) ==> When y=0
y-int: (0, 2) ==> When x=0

Explanation:
The nonstress test is done to determine the fetal movement, heart rate and activities inside the mother's womb. It is prenatal test which is used to check the fetal health. This test places no stress over the fetus and the mother. It is done after 26 to 28 weeks of pregnancy. The mother does not require to have a full bladder for the test. As this test do not put physical and mental stress on the body of mother thus the mother may go home alone. This test cannot be used for diagnosis of genetic disorders like Down syndrome or neural tube defect.
Answer:
Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.
The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.
