Biology TEKS Correlations
(4) Science concepts. The student knows that cells are the basic structures of all
living things and have specialized parts that perform specific functions, and that
viruses are different from cells and have different properties and functions. The
student is expected to:
(C)compare the structures and functions of viruses to cells and describe the role of viruses in causing diseases and conditions such as acquired immune deficiency syndrome, common colds, smallpox, influenza, and warts; and
28.
During the 1500s, European explorers introduced smallpox to the Americas. The death rate for the native
populations that were infected was 50% to 90%, whereas the death rate for infected Europeans was 10%.
What most likely accounts for the differences in the death rates?
A.
B.
C.
D.
29.
The Europeans took antibiotics for smallpox.
The native populations lacked immunity to smallpox.
The Europeans had a better diet than the native populations.
The native populations lacked shelter from the weather.
A teacher becomes sick with influenza. After missing school for three days, the teacher visits a doctor and
asks for a prescription for antibiotics. However, the doctor refuses to give a prescription because —
A.
B.
C.
D.
antibiotics only work if taken within 24 hours of becoming ill
influenza has become resistant to antibiotics
antibiotics would harm cells in the lungs
influenza is caused by a virus
The Biology TEKS (4)(C) does not require a list of diseases and their symptoms to be taught.
Nor does it focus on the lysogenic or lytic life cycle of viruses. It focuses on the idea that
viruses cause disease and why they are different from other disease-causing agents. Of
the two previous questions, the first asks students to think about disease in a historical
sense, and the next asks students to realize that treatment for viral diseases is different from
treatment for bacterial diseases.
