In designing your vaccine, you will need to choose an antigen or antigens to stimulate the adaptive response. All antigens are not created equal--there are certain characteristics that make more effective antigens.
1. Which of the following best describes why molecules such as glycoproteins are more effective antigens compared to molecules such as starch?
(A) In general, proteins stimulate stronger immune responses than carbohydrates such as starch.
(B) Glycoproteins have greater molecular mass compared to starch; therefore, they will elicit a stronger immune response.
(C) Since starch is a polymer of glucose (which is used by eukaryotic cells for energy), it is not recognized as foreign.
(D) Glycoproteins contain a variety of shapes and subunits that contribute to the overall complexity of the molecule.

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening

Explain why biological control methods are generally environmentally superior to chemical pest control methods.

What happens when water’s salinity increases? mass decreases. freezing point decreases. buoyancy of objects decreases. the amount of dissolved minerals decreases.
