a) innate

b) adaptive

2) T-cytotoxic (Tc) cells target and destroy tumor cells and cells infected by a virus. What type of immunkty is this?

a) innate

b) adaptive

Expert Solution

1) Plasma cells secrete antibodies in tears, swear, saliva, mucus, and breast milk that prevent pathogens from infecting body surfaces. What type of immunity is this?

a) innate

2) T-cytotoxic (Tc) cells target and destroy tumor cells and cells infected by a virus. What type of immunkty is this?

b) adaptive

Innate immunity is inherited by the offsprings from parents. This type of immunity prevents the pathogens from entering the body by forming the first and second line of defense, such as skin, tears, mucus etc. It is present in the organism since birth. Adaptive immunity consists of two components: humoral and cellular immunity. Humoral immunity is antibody mediated immunity that is secreted by B-cells in response to an infection. Cellular immunity consists of immune response by T-cells. Thus, antibodies in tears, saliva, breast milk etc., are components of innate immunity or non-specific immunity, while T-cell cytotoxic response is specific immune response and belongs to adaptive immunity.

Breast-feeding mothers secrete calcium into their milk. Some of the calcium may come from their bones, so mothers may lose bone mineral. Researchers measured the percent change in mineral content of the spines of 47 mothers during three months of breast-feeding. The sample mean is -3.587%. Let us assume that these 47 women as an SRS from the population of all nursing mothers. Suppose that the percent change in this population has standard deviation 2.5%. The hypothesized value μ0=−2.7% falls...
