Question 9

Active TB

Answer 9

Contagious bacterial infection that primarily affects the lungs

Question 10

anopheles mosquitos

Answer 10

Mosquito that can transmit the parasite responsible from malaria

Question 11

antibiotic resistance

Answer 11

when bacteria evolve to withstand the affects of antibiotics, making medication’s less effective in treating infections

Question 12

conjungation

Answer 12

process in bacteria, where genetic material is transferred between two cells, enhancing their abilities and characteristics

Question 13

directional natural selection

Answer 13

where a trait becomes more common in a population, because it provides a selective advantage

Question 14

horizontal gene transfer

Answer 14

Exchange of genetic material between different organisms (often bacteria)

Question 15

Latent TB

Answer 15

where a person is infected with TB bacteria, but does not show symptoms of(bacteria is inactive)

Question 16

Malaria

Answer 16

caused by plasmodium parasite transmitted to through mosquito bites

Answer 17

Bacterial responsible for causing tuberculosis in humans

Question 18

plasmid

Answer 18

small circular piece of DNA found in bacteria, carry extra genes that provide advantages such as antibiotic resistance

Answer 22

Enzyme that helps make RNA by reading instructions from DNA

Question 23

transcription

Answer 23

Process where genetic information in DNA is used to create a messenger molecule called RNA

Question 24

Transduction

Answer 24

method of horizontal gene transfer viruses help carry genes from one bacterium to another

Question 25

Transformation

Answer 25

Process in which bacteria picks up new pieces of genetic material from the environment
