why virus is imortal?​

Answers

Answer 1

Answer:

Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.

Explanation:

Answer 2

Answer:

A flu is a virus and the reason that you have to get flu shots every year is because every time a virus enters a host it is mutated by the antibodies, cells and biology of that host, so it can be passed on to another host who may not be immune to every part of this NEW virus.

Explanation:

So your answer is both yes and no.

2. Why must the satellite use electromagnetic
waves instead of sound waves?

Answers

Answer:

Since electromagnet waves do not need a medium they can travel through space. Sound waves can't travel through space because they need a medium.

Explanation:

The satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.

What types of electromagnetic waves are used by Satellites?

The types of electromagnetic waves that are used by satellites are known as radio waves. These waves are utilized in order to carry out satellite signals with a speed of 3000,000km/sec.

Electromagnetic waves facilitate the required amount of speed and characteristics which ease the transmission of information required by the satellites. Radio waves are traveling through the vacuum of space with the fastest speed at which the information via the satellite can be transmitted. Radiowaves are also used for spacecraft communications as well.

Therefore, the satellite uses electromagnetic waves instead of sound waves these types of waves do not require any medium for the transmission of the information.
