DESCRIBE WHAT IS HAPPENING IN EACH DIAGRAM

Biology
1 answer:
salantis [7]3 years ago

Answer:

In the first diagram the weakened pathogen (weaker version of the disease) is inserted into the bloodstream.

In the second diagram the antibodies kill the weakened pathogen. When the immune systems encounters a new disease it "remembers it".

This is why in the third diagram, when the "real" pathogen enters the bloodstream the immune system can effectively kill the disease. As the immune system "remembers" how to defeat the weakened version it can more effectively kill the "real" version.

The <em>correct</em> answer is:

Penicillium

Aspergillus

The lesson states:

If you've ever heard of or taken penicillin to fight off an infection, you can thank a member of the imperfect fungi called penicillium. Some mold species of penicillium are also important in the flavoring and aging of cheese. Roquefort and Camembert cheese owe their distinctive flavors to these fungi. Aspergillus is an imperfect fungus that is found on decaying food. It also contributes to the production of organic acids like citric acid. <u>Both penicillium and aspergillus produce enzymes that are purified and used in various industrial compounds and in medicine.</u>

If the DNA nucleotides read 3'-ATG-CGT-GAC-5', the amino acid sequence of the resulting polypeptide
Marat540 [252]

Answer:

5’ – TAC-GCA-CTG-3’

Explanation:

As per the Chargaff’s complementary base pairing rule purine always pairs with a pyrimidine.  

Purines include adenine (A) and cytosine (C)

Pyrimidine include thymine (T) and guanine (G)

Thus an A always pair with T and C always pair with G

Thus, the resulting poly peptide for the given amino acid sequence is  

3'-ATG-CGT-GAC-5'

5’ – TAC-GCA-CTG-3’

If you were traveling across the Atlantic Ocean taking rock samples from the sea
Anon25 [30]

The rocks would be younger the closer you get to the ridge

The Mid-Atlantic ridge is a divergent tectonic boundary in the middle of Atlantic Ocean spanning north to south.

Explanation:

At a divergent boundary, a phenomenon called seafloor spreading occurs as new crust is formed along the ridge. New crust seems to 'spread' from the ridge. Therefore, the farther away from the ridge you get, the older the crust gets. This occurs because magma from the mantle rises to replace the void created by the tectonic plates moving away. The magma rises and cools creating a mountainous ridge long the boundary. Seafloor spreading, however, happens really slowly and the changes are only perceptible over 1000s and millions of years.
