Answer:
Observation
Explanation:
They are observing the way that population has decreased
Answer/Explanation:
Two unaffected parents can have affected children, that means cystic fibrosis must be a recessive trait.
The two parents must each have one copy of the cystic fibrosis allele, but are themselves unaffected. By chance, the son (shaded) inherited both of these copies and is affected. The daughter either inherited one or zero copies of the cystic fibrosis allele, as she is unaffected.
If snails can't find a shady moist environment, they will most likely die. but baler snails live in a small communities and don't travel far. not sure if that helped but i thought i could give you some info:)
Answer:
Instead of physically trapping drugs into vesicles, amphiphilic phospholipids in pharmacosomes are complexed with drugs via hydrogen bonds between active hydrogens and phospholipids. The drug molecule bearing an active hydrogen atom (-COOH, -OH, -NH2 etc.) can be converted to an ester with the hydroxyl moiety of the lipid, resulting in an amphiphilic complex that aids membrane, tissue, or cell wall transfer. The drug-lipid complex exists as a monomer at low concentrations, but a variety of structures (e.g. micelles, colloidal or hexagonal shape) might develop when the concentration increases. Eventually, the conjugated drug will be released from pharmacosomes upon chemical or enzymatic hydrolysis. Compared to other liposomal drug delivery systems, pharmacosomes have advantages such as minimized drug degradation and increased drug bioavailability. For example, limitations in transfersomes such as predisposition to oxidative degradation and impurity of natural phospholipids can be overcome by pharmacosomes. Besides, other advantages are also beneficial in various research:
No drug leakage due to the covalently link.
High entrapment efficiency.
Suitable for both hydrophilic and lipophilic drugs.
Improved bioavailability especially in case of poorly soluble drugs.
No need to remove unentrapped drugs from the formulation as needed in case of liposomes.
Reduction in adverse effects, toxicity, and the cost of therapy.
Avoid drug incorporation in the body of the patient.
Membrane fluidity does not affect drug release.
