<h2>Answer:</h2>

To obtain more amount of single cell, a method called <u>cell culture</u> is employed.

<h2>Explanation:</h2>

Cell culture, otherwise called limited cells, will be cells that are legitimately arranged from a life form's tissues. Whenever placed under the correct conditions essential cells will develop and multiply, however they are just ready to do so a limited number of times. As far as possible is identified with the telomere length toward the finish of the cell's DNA.

As cells experience every cell division, a little portion of the telomere is lost after each time DNA is copied. This procedure in the long run prompts a phase of senescence, where the cells can never again separate. Persistent cell lines, then again, can get away from the ordinary limitations of the cell cycle and develop inconclusively, making them incredibly helpful for long haul inquires about.

max2010maxim [7]

Answer:

4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work

Explanation:

Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.

The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.

Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.

Design an experiment to determine whether the pink flower of petunia plants results from incomplete dominance.
anzhelika [568]

Answer:

To cross petunia plants/lines with pink flowers (F1) which were obtained by crossing plants with red and white flowers (parental generation). The presence of petunia plants with red or white flowers in F2 would evidence that this trait is under incomplete dominance.

Explanation:

Incomplete dominance is a type of relationship in which both alleles are expressed in heterozygous individuals, thereby resulting in a new phenotype. This type of allelic interaction is commonly referred to as 'the dilution of the dominant allele' in heterozygous individuals. Moreover, codominance refers to a type of allele relationship in which both alleles are expressed to an equal degree in heterozygous individuals.

Why do cells need to make a copy of DNA before division?
tino4ka555 [31]

Answer:

So that the end products (new cells made from the division) will both have DNA to run all its processes to reproduce.
