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.

To contract and churn the food to break it down into smaller molecules
The answer which is false is, gene flow leads to divergence and the formation of new species.
What is speciation?
For speciation to occur two populations must be prevented from interbreeding.
This means that populations must become isolated from on another through the geographical or biological barriers.
If populations remain isolated long enough, speciation will eventually occur because of changes accumulated in population due to natural selection.
What is gene flow?
Geographical isolation hampers gene flow because of spatial separation which in turn leads of reproductive isolation due to the inability of meeting gametes to leads.
It causes genetic drift due to the barrier of gene flow between them and parent species.
Certain alleles get fixed into population due to inbreeding in a smaller population while other gets eliminated, this leads to formation of new alleles and new gene pool, so-called progressive genetic divergence.
Finally there is the formation of new species when genetic variation are accumulated for several generations.

Answer:
Different genes are expressed in different cells
Explanation:
The instruction is provided to the cell by the genetic material in the form of genes. Genes are the physical segment present on the DNA which can code for a specific protein.
The genes are present in the cells in the condensed form called chromosome which is present in all the cells of the body.
Although all the cells contain the same type of chromosomes or genes but they differentiate to perform different functions.
The differentiation process involves the expression of different genes in different cells as a result of which different proteins are formed in different cells and they perform different functions.
