Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.

How many new volumes would each new cell contain whenever a cell splits?

Elenna [48]

The specific volume will be different for various kinds of cells. The safe answer would be that the new cell will pretty much have the same volume as the one that it divided from. This is true for most eukaryotic cells unless other factors like epigenetics or mutations come into place.

One example of moments a cell would increase in volume is during hypertrophy. This simply means that the cell is increasing in size (compared to: hyperplasia -- which is an increase in number of the cells). Hypertrophy is definitely an increase in volume of the cell but this doesn't necessarily translate to cell division (i.e. just because the cell is big now, doesn't mean it will still be big when it divides).

Another moment of increasing volume of the cell and now also related to cell division would be during the two stages in the cell cycle (i.e., G1 and G2 phases). This is the growth phase of the cell preparing to divide. However when mitosis or division happens, the cells will normally end with the same volume as when it started.

This are safe generalizations referring to the human cells. It would help if a more specific kind of cell was given.

The chromosomes of offspring are not identical to those of their parents or siblings because ______ is shuffled during meiosis.

tigry1 [53]

The chromosomes of offspring are not identical to those of their parents or siblings because genetic information is shuffled during meiosis.

Meiosis can be described as a cell division process by which gamete cells divide. The number of chromosomes is reduced to half in this cell division process.

During the process of meiosis, genetic information is shuffled between non-sister chromatids of the homologous chromosomes. This shuffling process is referred to as crossing over. A new combination of alleles is formed due to the process of crossing over.

It is due to the process of crossing over that the organisms produced are not identical to each other or the parents. Genetic diversity is important in order for populations to survive which is possible through the process of meiosis.

When the comb jelly, Mnemiopsis leidyi, was introduced into the Black Sea, its population exploded to 500 comb jellies per cubic

nikitadnepr [17]

The answer is invasive species.

Invasive species are species that are not native to specific ecosystem, but they have a capability to spread widely through the ecosystem, This way they can threaten native species of the ecosystem or cause environmental harm.

After being introduced into the Black Sea, they greatly affect local ecosystem. In the new area, they have no natural predators and are able to spread. If they spread beyond the area they are introduced, they become invasive species which can overgrow native biotopes and are a great threat to the local biodiversity. This could lead to the extinction of some native species.
