What usually happens to the host’s DNA during the lytic cycle?

Answers

The lytic cycle is one of the two phases of reproduction in viruses. In this part of reproduction, the viral RNA joins with the DNA of the host and copies itself into the host's DNA pattern. This will cause the host cells to reproduce the viral cells instead of the original host cells. Overtime as the viral cells continue to reproduce they will overload and eventually cause the host cell to explode. When this occurs, then the produced viruses will continue on to infect the next cell.

Which will have more resistance: 220V, 100W bulb or a 220V, 60W bulb?

Answers

The power dissipated by something with voltage across it is

(voltage)² / (resistance) .

You can see that resistance is in the denominator of the fraction,
so larger resistances dissipate less power, and smaller resistances
dissipate more power.

Here's an easy way to remember it:
-- Connecting a piece of rubber (high resistance) across the terminals of a battery
uses very little power from the battery.
-- Laying a piece of wire (low resistance) across the terminals of a battery
may draw so much power from the battery that the wire melts.

Since the voltage across both bulbs is expected to be the same, the bulb
designed to dissipate 60 watts has higher resistance than the one designed
to dissipate 100 watts.

Briana builds a circuit that has a resistance of 8.0 . What voltage should she apply to have a current of 0.8 A?

Answers

Given : R= 8.0 ohms I= 0.8 amps

Unknown: electric voltage (V)=?

Formula: V=IxR

Solution: V= 0.8 x 8.0=n

Answer: 6.4 volts (V) electric voltage

The correct answer is:

B. 6.4 V

A voltage 6.4 V should be applied to have a current of 0.8 A.
