max2010maxim [7]

Answer:

Hydrolysis.

Explanation:

Maltose is produced by hydrolysis of starch, in the presence of amylase, can be detected by colorimetric assay. As per the assay of hydrolysis of starch we have concluded from the test of enzyme activity of amylase is that maltose being a reducing sugar which reacts and reduces the DNS (3,5-dinitrosalicylic acid) that is basically a pale yellow colored alkaline which results after some minutes into 3-amino,5-nitrosalicyclic acid which orange red colored alkaline after heating.

For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to
umka21 [38]

Answer is (E) : Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.

Let me explain you why. Hershey and Chase conducted their experiment to show what is the genetic material that passes from one generation to another generation. Is it protein or DNA? For explaining this, they allowed the virus to grow in the presence of two different radio active elements.

In one set they grew viruses in the presence of P-32 radio-active element  

In another set they grew viruses in the presence of S-35 radio active element.

The reason why they choose these two radio-active element was, phosphorus is present in DNA but not in proteins and similarly sulphur is found in proteins but not DNA.

These viruses were allowed to infect bacteria and the later was observed to be radio-actively labelled with P-32 but not S-35. This clearly showed that DNA is the genetic material which was passed from virus to bacteria.  

Now if you choose Nitrogen for labeling, it won't help you in getting any conclusion since nitrogen is present in both proteins and DNA.

How does the Arthropod growth curve differ from the growth curve of most other animals?
wel

Answer:

Unlike a steady pattern of growth, arthropods exhibit an external growth that proceeds in a sequence of step-like jumps, as the organism builds and replaces its exoskeleton. The arthropod does not grow bigger in size between these jumps. An aquatic arthropod gradually replaces body mass for water detained inside the tissues between molts.
