Answer: the question is <u>What activities of the body are responsible for the sympathetic nervous system and for which parasympathetic? </u>
is it right thats what the question means?
answer in eng: The sympathetic division initiates the fight-or-flight response and the parasympathetic initiates the rest-and-digest or feed-and-breed responses. The sympathetic and parasympathetic nervous systems are important for modulating many vital functions, including respiration and cardiac contractility.
answer in polish: Podział współczujący inicjuje reakcję walki lub ucieczki, a przywspółczulny inicjuje reakcje odpoczynku i trawienia lub karmienia i rozmnażania. Współczulny i przywspółczulny układ nerwowy jest ważny dla modulowania wielu funkcji życiowych, w tym oddychania i kurczliwości serca.
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.
Endocytosis is taking stuff in while exocytosis is getting rid of the stuff and putting it out
Let a be Q, all which is homozygous recessive = Q∧2
A = p, AA which is homozygous recessive = Q∧2
2pq = heterozygous
It is derived from p+ q = 1
All those in a population which is Q = 20%
All A in the population (p) = 80%
Now that the disease is homozygous recessive therefore,
aa = qq or q × q = 0.20 × 2 = 4%
Then the answer is 4%.
