Lytic Cycle
1) In the lytic cycle, what does the bacteriophage attach to on the host cell membrane?
2) After the virus attaches to the host cell membrane what is injected into the host cell?
3) What is another way a virus can enter a cell?
4) The viral DNA/RNA contains instructions for the cell to do what?
5) What can happen to the cell membrane after making many copies of the virus?
6) What do the viruses do once they leave the host cell?

Lysogenic Cycle
7) What happens to the host bacteria’s DNA after the bacteriophage injects its DNA/RNA into the cell?
8) The bacteria pass this “combined” DNA onto daughter cells. The bacteria continue to reproduce and finally enter the lytic cycle when this happens.
9) Once the bacteria are “activated” they begin producing
10) What two things can trigger bacteria to go into the lytic cycle?
11) When you catch a common cold, your body’s immune system fights the infection by producing white blood cells called
12) The HIV virus binds to the CD4 receptor on what type of cell?
13) Since the HIV virus attacks a person’s immune system it can make people vulnerable to other
14) A virus that targets pest insects could be an alternative to

1) a susceptible bacteria

2) The virus's DNA/RNA

3)  Viruses enter through the cell membrane via injecting it's DNA genome into the cytoplasm of the bacterium

4) Reproduce and make new copies of the virus

5) It pokes holes in the cell membrane

6) They either die off or find another host cell in the body

Lysogenic

7) It recombines with the phage DNA

8) Under the right conditions.

9) They produce more DNA/RNA

10) Triggers like UV light or lack of nutrients can cause the switch.

11)  leukocytes

12) T-Cells

13) Viruses

14) Antibiotics/ penicillin

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
