Answer:
When cellular membranes form, phospholipids assemble into two layers because of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the aqueous or watery environment on either side, and the tails hide away from the water between the layers of heads, because they are hydrophobic.
Explanation:
11. Cytoplasm
14. Cell wall
Answer: population density
Explanation:The number of individuals living within that specific location determines the population density.
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.
<span>Coevolution is a process whereby two species, through their interactions with one another, can influence the evolutionary paths of one another. For instance, what may start as a symbiotic relationship between two species may lead those species to specialize in terms of their strengths such that they evolve characteristics that make them more or less reliant on one another as a result, something that would not have occurred otherwise.</span>
