If your lac operon looked like the image below, which of the following can you infer?You had cereal and milk for breakfast.
Your lac operon is expressed.
You have not consumed lactose from dairy recently,
None of the above.

Answers

Answer 1

Answer:

Answer:

You have not consumed lactose from dairy recently

Explanation:

According to the diagram, there is a represssor element in the regulatory region of the operon. This repressor is blocking the RNA polymerase, that is bound to its promoter region upstream of the genes, from transcription. The repressor is mostly the lac repressor that switches of the operon in the absence of lactose.

The varicella virus is a common childhood virus that causes chicken pox. Shingles, a disease alsocaused by varicella, often occurs in adults. What does this indicate about the varicella virus?
It is a bacterioptrage.
It undergoes a lysogenic cycle.
H.
It does not contain a viral envelope.
J.
It does not kill host cells after infection.

Answers

Answer:

The correct option is : It undergoes a lysogenic cycle.

Explanation:

A virus can replicate inside a host cell by two process :

Lytic cycle

Lysogenic cycle

In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.

In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.

What is Newton's first law of motion?

Answers

Its basically saying something (object) at rest is going to stay there until something moves it like an outside object.

Answer:

In essence, Newton's first law of motion states that an object at rest won't move unless an outside force causes it to move. Similarly, an object moving at a constant speed will continue moving at that same speed indefinitely, unless an outside force causes it to change speed.

Viruses use the cells of living organisms to reproduce. What is the type of cell used by the virus called?parasite
host
partner
--------
Why do most biologists believe that true commensalism does not exist?
an ecosystem usually has more parasites than hosts
animals of different species usually do not like to work together
the relationships are probably mutual or parasitic
animals of the same species rarely compete with one another
