The phospholipid bilayer is a universal component of all cell membranes. Each phospholipid molecule has a hydrophobic(water repelling) and a hydrophilic( attracted to water) end. This allows the phospholipids to arrange themselves in a way that makes a cell membrane not able to dissolve in water. The bilayer is also semi-permeable which allows only certain molecules to enter the cell.

YES your correct answer will be the letter B
Answer:
The best answer to the question: If every gene has a tissue-specific and signal-dependent transcription pattern, how can such a small number of transcriptional regulatory proteins generate a much larger set of transcriptional patterns? Would be:
Because transcriptional regulators, which are the ones responsible for initiating, and stopping, transcription of RNA into protein, often work in pairs, one goes with the other, and thus increase the regulatory capabilities over gene expression so that the genes translated into RNA and then transcribed into aminoacids in protein chains, actually code for the correct protein types.
These regulators will both stand, as appropriate, on a specific gene to promote its transcription, or prevent it, depending on the different signaling mechanisms received.
Answer:
No, because he will not have broken covalent bond.
Explanation:
Denaturation is the process adopted to affect or alter the chemical structure of a protein. This can be done or achieved by heat or addition of acid.
Denaturation can't break the peptide bond of the protein , this means that the , amino acid sequence is unaffected after the process.
Physiological pH is the pH Darin won't be able to have amino acid because the pH at which denaturation was being carried is basic, while the process requires acidic medium.
Collagen is a form of protein that can be found in the body.
Answer:
1.a variable (often denoted by x ) whose variation does not depend on that of another.
2.a variable (often denoted by y ) whose value depends on that of another.
3.Control group, the standard to which comparisons are made in an experiment. ... A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment
4.occurring continuously over a period of time.
