Answer: What is the defining characteristic of eukaryotic cells? Put these in your own words.

Eukaryotic cells are defined by the presence of a nucleus containing the DNA genome and bound by a nuclear membrane (or nuclear envelope) composed of two lipid bilayers that regulate transport of materials into and out of the nucleus through nuclear pores.

What types of organisms have eukaryotic cells?

There is a wide range of eukaryotic organisms, including all animals, plants, fungi, and protists, as well as most algae. Eukaryotes may be either single-celled or multicellular.

Wewaii [24]

Answer:

D) The lac operon will function normally.

Explanation:

  • The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream.
  • The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.
  • so correct option is D) The lac operon will function normally.

A child was exposed to a disease-causing virus (most likely chicken pox from the Varicella zoster virus) when he was 5 years old
STatiana [176]

Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.

Explanation:

When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.

As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.

Thanks to its memory cells, the virus will remain much less time in the body.
