Korvikt [17]3 years ago

Answer:

B.

Explanation:

The rise in the acids levels of the sea water is caused by the dissolve of CO2 in sea water which lowers the pH.The resultant unstable  compound(weak acid) formed is H2CO3.The latter dissociates to for HCO3 + CO3- These  reversible products are the buffers in the seawater that resists the fluctuation in the pH. The carbonate ions reacts with the high concentrations of  Ca + in the sea water, to form  the exoskeleton s of some  fauna.e.g.,Mussels.

At 20°C the enzyme that catalyzes the breakdown of polysaccharides functions at 1 reaction every 20 microseconds. If this enzyme
lora16 [44]

Answer:

Seven segments

Explanation:

As given in the question -  

After every  twenty microseconds one reaction occurs i.e breakdown of polysaccharides.  

This means that after every  twenty microseconds the polysaccharides is broken down  

The total time for this hydrolysis reaction is  120 micro seconds

Thus , there will be six phases of division each after every  twenty microseconds

After 1st  twenty microseconds , total segments is equal to two

After 2nd  twenty microseconds , total segments is equal to three

After 3rd  twenty microseconds , total segments is equal to four

After 4th twenty  microseconds , total segments is equal to five

After 5th twenty  microseconds , total segments is equal to six

After 6th twenty microseconds , total segments is equal to seven

aivan3 [116]

Answer:

DNA ligase

Explanation:

DNA replication is an enzyme mediated, 3-step process during which the DNA molecule produces a copy of itself. The 3 steps involved are as follows;

  • initiation
  • elongation
  • termination

<em>Initiation </em>involves the unwinding of the double helix structure of the DNA using DNA helicase enzyme

<em>Elongation</em> involves binding of RNA primer to the DNA strands and addition of bases to the primer<em> </em>to elongate the new chains. Bases are added to the leading strand continuously while the lagging strand is replicated in short segments (okazaki segments).

<em>Termination</em> involves the unbinding of RNA primer and substitution of its bases by DNA bases. The Okazaki fragments are then joined together using the DNA ligase enzyme.

<em>The short, numerous segments of DNA observed in the mixture is the Okazaki fragments of the lagging strand. This is due to the absence of the enzyme involved in the joining of these fragments.</em>

Hence, the answer is DNA ligase.
