Exam 7: Understanding Natural Selection, Vaccines, and Viral Reproduction

From the list provided, select all viruses that have DNA as the genetic material. (Check all that apply.)

One method of constructing an influenza vaccine is to use an influenza strain that has been modified by removing proteins that contribute to its virulence. This process is called __________.

The following statements relate to either the innate or the adaptive system. Select those thatonly apply to the adaptive immune system. (Check all that apply.)

From the list provided, select all that are provided by studying transitional fossils. (Check all that apply.)

Which of the following events would result in the formation of an influenza virus that would threaten humans?

Which of the following best distinguishes viral genetic material from the genetic material of a living organism?

The contents of genes in viruses are ______ that of living organisms.

What is the first reaction of the body due to the influenza virus disrupting the normal function of the epithelial cells in the respiratory system?

Explain the process of natural selection as a mechanism of evolutionary change.

From the list provided, select all characteristics of the influenza envelope. (Check all that apply.)

Which of the following best describes the action of B cells?

Which of the following types of cells would a flu virus most likely target as the means of entry into the body?

New influenza vaccines are being developed that may lessen the effect of the rapid evolution of the viral strains. One way is to develop a universal influenza vaccine that uses ______ as an antigen.

Trials of the universal influenza vaccine, H1ssF_3928, began in

When two different forms of a virus infect the same cell, the host cell may manufacture viral particles from both viruses to reassemble them into a new form of virus. This process is called __________.

The ______ glycoproteins are presented by all nucleated cells and an identification tag. The ______ glycoproteins are only presented by cells to provide the link between nonspecific immune responses.

The process of ______ helps biologists relate the natural world and how organisms have changed over time in response to the natural world.

From the list provided, select the two circumstances necessary for evolution to occur.

The ______ process to make influenza vaccines, only uses a small portion of the H spike protein that helps the immune system identify the actual virus.

The closer two organisms are related, the more time there has been for mutations to occur in the genetic information.
