It is hard to understand this question but ill give you my best answer. The hearts level of organisation to cells is immense, the heart pumps blood to every cell in the body (so they can respire) through a system of Arteries, veins and capillaries. The blood is pushed by the force of the heart through the arteries, the main (and largest) tubes for transportation to segments of the body further away from the heart. This goes into a smaller system of veins that brake off into a tree kind of pattern to reach every cell. These later brake off into the capillaries that have walls only 1 cell thick. This is how blood is transported to each cell that requires energy and oxygen to respire.
The hydrophobicity plot tells us about the location of transmembrane helices.
<h3>What is hydrophobicity plot?</h3>
- Hydrophobicity plots are used to predict the location of turns in proteins.
- In 1982, Kyte and Doolittle gave a hydrophobicity scale which gives each amino acid a hydrophobicity value.
- A hydrophobicity plot is drawn between the residue number versus residue hydrophobicity.
- These hydropathy plots are used to determine the transmembrane helices of proteins.
- The transmembrane helices are present in the non polar area (hydrophobic) of the lipid membrane whereas the other parts are present in polar areas (hydrophilic).
- Thus by computing the hydrophobicity value and plotting it on a graph we can find the loops and turns in proteins.
- Nowadays there are many hydrophobicity scales determining the hydrophobicity value of amino acids.

Well the offspring of the original cell are considered daughter cells (as they all reproduce) so with the knowledge I know when the cell doubles it’s going to look exactly like the mother cell and not just look but they all have the same job, which is to multiple. So I think that might be the answer. But if it’s multiple choice then I might be wrong because you didn’t provide any options.
