What stages of replication do both cycles have in common? Describe the virion action at each of these stages.

Answers

Answer 1
Answer:

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 2
Answer:

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.

The human genome codes for 20,000 to 25,000 proteins, but any given cell might produce only 5,000 different proteins. how is this possible?

Answers

This is because not all genes are expressed at the same time, so not all the proteins are present at a certain moment. The mechanisms that cell uses to control gene expression are called regulation of the gene expression. Thanks to regulation of the genes, cells have the ability to increase or decrease the production of specific gene products such as proteins. This property is important for the adaptability of an organism because it allows the cell to express protein when needed.

Based on each person's statements, identify which of the following you AGREE with, and then explain your reasoning. Courtney: “It is obvious that everything that eats plants would die but all the other organisms on the island would be okay.”

Jose: “Courtney I think the organisms that eat plants would just learn to eat other things. So initially they might decline in numbers but eventually, their numbers would increase back to their current amount.”

Raquan: “I have to disagree with both of you. I think that all of the organisms on the island would die, because at some point even the mammals who don’t eat plants directly would ultimately discover that what they usually ate has already died.”

Mike: “I kind of agree with Courtney, except I don’t think that all of the things that eat plants will die. I think the things that eat both plants and animals would live and only those that can’t or won’t eat animals will die.”

Keisha: “Mike is right. I would add that since there are fewer things for the larger mammals to eat that we would ultimately see fewer of them on the island.”

Alex: “I argue that organisms that eat plants would learn to swim so they can eat the seaweed and algae in the water.”

Digestion and breathing are _____. controlled by ganglia and plexus reflexive actions controlled by the spinal cord voluntary actions controlled by the central nervous sytem

Answers

Answer:

The correct answer is - reflexive actions controlled by the spinal cord.

Explanation:

Digestion and breathing are examples of involuntary action which is controlled by the autonomic nervous system of the CNS. however, the part of the nervous system that controls is the spinal cord and hind brain by the spinal reflex actions.

These are the action they do not require any thought and work without any thought that leaves the brain for other actions and coordinations. specific but the same stimuli causes the response in the same way.
