The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
<h3>What are liposomes?</h3>
Liposomes are vesicles which are made up of a lipid bilayer membrane.
Liposomes are important as delivery vehicles for substances such as drugs.
Ultrasonication is a method of liposomes preparation.
Solution of liposomes is dependent on the size.
The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.
Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.

Answer:
Answer is 2. Fibroblasts fail to divide.
Explanation:
Tissue culture experiment is the experiment where tissues are grown in an artificial medium. This involves the use of growth medium such as agar or broth. This process help to produce needed tissues in a short period of time.
Fibroblasts are cells which are found in the collective tissues, and they produce collagen. The collagen produced by the Fibroblasts play important role in tissue repair. Fibroblasts are regarded as the main cells in the connective tissue.
Note that, PDGF, which is Platelet -derived growth factor in full, is a growth factor regulating cell growth and it's division.
The gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.
