In place of thymine, what does RNA use as a base <br><br> Please help
11111nata11111 [884]
The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine. Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA.

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.

How are global warning and El Nino similar? Is it possible to use effects of El Niño as evidence of potential dangers of global
Angelina_Jolie [31]

El Niño as evidence of potential dangers of global warming to marine ecosystems

Explanation:

El Nino, an abnormal type of weather pattern, causes huge climatic variations globally by bringing floods in one region and drought in another region. These extremely changing patterns in weather can damage human life, agriculture, air quality, natural ecosystems, etc all of which might lead to global warming.  

El Nino effect is a serious potential danger to the marine life. This causes variations in the sea surface temperature, ocean currents, and upwelling patterns. Due to this, many marine organisms either migrate to newer places or do not survive the change.

Due to this, other sea animals depended on them also are depleted of their food source. El Nino also impacts the structure of coral reefs causing coral bleaching which in turn affects the marine life.
