Q3. How does the fact that DNA Replicates semiconservatively decrease the

1 answer:

7 0

If the DNA polymerase did nothing special when a mispairing occurred between an incoming deoxyribonucleoside triphosphate and the DNA template, the wrong nucleotide would often be incorporated into the new DNA chain, producing frequent mutations. The high fidelity of DNA replication, however, depends not only on complementary base-pairing but also on several “proofreading” mechanisms that act sequentially to correct any initial mispairing that might have occurred.

Compare a natural meadow with a cornfield in terms of biodiversity. in your answer, be sure to address the: • number of species

Mademuasel [1]

In a cornfield, only one plant species has dominated the area, that is the corn plant. While in a natural meadow, multiple species of plants occurs of different species. The presence of the different types of plants in the meadow will interact more number of insects in it as compared to the corn field. This will lead to more interactions among the different species in a natural meadow. The greater biodiversity of the natural meadow than the cornfield will support it better.

In case of any natural disaster, or a pest attack, all the plants will be killed in a corn field and so will the insects dependent on them, but in a natural meadow, if one plant species is killed by a natural disaster, other will still be alive. Hence, the ability to survive is greater in natural meadow.

A laboratory experiment requires 250 milliliters of water for boiling. It also requires 100 milliliters ofw

lakkis [162]

Answer:

550 milliliters of water is needed.

Explanation:

the student will need 550 milliliters of water for completing the whole experiment. 250 milliliters of water is needed for boiling purpose while on the other hand, 100 milliliters of water is needed for one process which can be repeated three times so the process needs 300 milliliters of water so by combining the 250 milliliters and 300 550 milliliters of water we get 550 milliliters of water for the whole experiment so we can say that the student needs 550 milliliters of water for the experiment.
