The correct answer is option A

All the chemical reactions that takes place in the body of the organism occurs by the help of enzymes. These enzymes acts as the catalyst by increasing the rate of reaction. This increased rate of reaction is done by lowering the activation energy. The energy required to start the reaction is termed as the activation energy and the the enzymes functions by lowering this energy.

Advocard [28]

The options are:

A. They are genetically different from the parent because they are produced by sexual reproduction.

B. They are genetically identical to the parent because they are produced by sexual reproduction.

C.  They are genetically identical to the parent because they are produced by asexual reproduction.

D. They are genetically different from the parent because they are produced by asexual reproduction.

Answer:

The correct answer is- C.  They are genetically identical to the parent because they are produced by asexual reproduction.

Explanation:

<em>E. coli </em>reproduces through binary fission in which the genetic material of cell of <em>E. coli</em> first duplicates and then the cell elongates and each of the copies of their genetic material is moved to opposite poles.  

After this, the cell gets divided into two equal daughter cells. As binary fission is an asexual reproduction so there is no mixing or combination of genetic material from other <em>E.coli</em> therefore the resultant daughter cells are identical to the parent cell.

Therefore the correct answer is option c.

When a volcano erupts actually slightly acidic with a pH of just over 6. This is due to the rain it releases gases such as Sulphur Dioxide into the air which makes the rainwater more acidic with a pH of about 4.
