Answer;

-Genetic heterogeneity and epistasis.

Explanation;

-Marfan syndrome is a genetic disorder that affects the body's connective tissue that holds all the body's cells, organs and tissue together.

-Genetic heterogeneity is defined as mutations at two or more genetic loci that produce the same or similar phenotypes. Genetic heterogeneity may be either; allelic heterogeneity, which occurs when a similar phenotype is produced by different alleles within the same gene; or locus heterogeneity, which occurs when a similar phenotype is produced by mutations at different loci.

-A gene is said to be epistatic when its presence suppresses the effect of a gene at another locus. Epistatic genes are sometimes called inhibiting genes because of their effect on other genes which are described as hypostatic.

-From these descriptions the marfan syndrome demonstrates both genetic heterogeneity and epistasis.

The chemical energy of these plants all started with what energy source?
Zielflug [23.3K]

Answer:

Sun(solar energy)

Explanation:

The sun is the ultimate source of energy in our solar system.

The chemical energy in plants all started out with solar energy from the sun.

During the process of photosynthesis;

  • green plants manufactures their food using sunlight.
  • in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.

Photosynthetic reaction simply converts solar energy from the sun into chemical energy.

Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.

: the pertussis toxin was found to interfere with the ligand-binding site in g-protein coupled receptors. at which point in the
Ronch [10]
The point at which the toxin would interrupt normal cell signalling in the pathway is the signal amplification. 
This is because of the G-protein uncoupling and inhibition of signal amplification by pertusis toxin. Pertusis toxin released by the bacteria Bordetella pertusis and prevents signal that is amplifying from the protein. The G-protein coordinates the interaction between membrane bound receptor proteins and the effector proteins involved in the intracellular signalling. The toxin promotes the uncoupling of this heterotrimetric protein and also inhibits the amplification thus preventing the interaction of the receptor proteins and the second messengers.
