True. isotopes of uranium i.e U 235 is used as nuclear fuel in power plants

OleMash [197]3 years ago

Answer:

True

Explanation:

The following two isotopes of Uranium which are prominently used in a nuclear chain reaction.

a) Uranium-233

b) Uranium-235

Uranium 235 consists of 92 protons and 143 neutrons. When an excited electron hits a Uranium atom, it splits into two smaller atoms and release heat energy under the process of fission.

There is another isotope of Uranium i.e Uranium -238, but it does not break easily and hence is less preferred for a nuclear reaction.

Thus, it can be said that the statement "lsotopes of uranium are used as nuclear fuel in power plants." is true.

. Imagine the following scenario. A bacteriophage taken for the treatment of cholera infects a cholera-causing bacterium and tem
SSSSS [86.1K]

Answer:

The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.

Explanation:

The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.

As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.

This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.

Why is it difficult to observe individual chromosomes with a light microscope during interphase?
asambeis [7]

Answer:

They have uncoiled to form long, thin strands.

Explanation:

Chromosomes are present in cell nucleus and consist of chromatin. Genes are present in linear order on chromosomes.  The chromosomes become visible under the microscope as distinct structures during cell division. When cells are not dividing, the chromosomes decondense to loose their individuality and make the mass of chromatin.  

Chromatin is complex of DNA and packing proteins. As the cells enter the prophase stage of cell division, condensation of chromatin occurs and individual chromosomes become visible under microscope. Before that (during interphase), chromosomes are not visible as they are present in decondensed form.
