Why are certain amino acids defined as essential for human beings?

The stages of replication is  Attachment, Penetration and Replication

The following information should be considered:

• A bacteriophage means the virus that attacks bacterial cells.
• The lytic and lysogenic cycles comrpise of two methods of viral replication.
• In the lytic cycle, the virions generated are released from the host cell while on the other hand in the lysogenic cycle, viral nucleic material are existed into host nucleic material and also they are copied to daughter cells at the time when the host cell reproduces.

The common steps in both cycles are given below:

1. Attachment – in this step, the bacteriophage attaches itself to the host surface cell to insert its DNA into the host cell.
2. Penetration – the virus inserts its DNA into the host cell via penetrating the cell membrane of the host cell.
3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

Answer:

Attachment, Penetration and Replication

Explanation:

A bacteriophage is a virus that attacks bacterial cells. The lytic and lysogenic cycles are two methods of viral replication. In the lytic cycle, the virions produced are released from the host cell whereas in the lysogenic cycle, viral nucleic material are incorporated into host nucleic material and are copied to daughter cells when the host cell reproduces. The common steps in both cycles are given below:

1  Attachment – in this step, the bacteriophage attaches itself to the surface of the host cell so as to insert its DNA into the host cell.

2. Penetration – the virus inserts its DNA into the host cell by penetrating the cell membrane of the host cell.

3. Replication – the viral nucleic material is replicated using the host cell's replication mechanism.

Acute stress comes with a lot of adrenalin and for most people living ordinary lives lacks that. -hope this helps have an amazing day!!

Whenever POPs move thousands of kilometers from their source of release throughout a cycle is described as a "Grasshopper effect".

• Global distillation occurs when prevailing ocean as well as atmospheric currents transport toxins towards the Arctic, where they have been confined by the freezing environment.
• This would be known also as the "grasshopper effect," since chemicals constantly evaporate as well as condense during their way towards the Arctic.

Thus the response above i.e., "Option b" is right.

Answer:

b. grasshopper effect

Explanation:

Persistent Organic Pollutants or POPs are organic chemicals that cause a lot of damage to environment and living beings. They are generally industrial chemicals or pesticides for example, DDT. They are toxic and not degraded easily. They tend to get accumulated in living tissues and increase in concentration as we move upwards in a food chain.

When POPs are transported to areas far from their original site, the phenomena is called as grasshopper effect. They are carried by wind in atmosphere and finally settle down on land from where they evaporate again to enter the atmosphere. Thus, the cycle continues. Eventually, they can reach to an area thousands of kilometers away from their original source.
