Question 1:
Exons are gene fragments whose DNA sequence after transcription is found in mature mRNAs. This part of the gene is most often coding.
The size of the exons in the genomes follows a log-normal distribution, with an average length of about 150 nucleotides, knowing that in eukaryotes, each gene contains several exons and introns (an average of 8) so the size is 8*150 = 1200 bp.
Question 2:
Introns are fragment of a gene located between two exons. Introns are present in immature mRNA and absent in mature mRNA. "Non-coding" fragment of the gene.
The introns average in a gene is 3365 bp including 3'UTR and 5'UTR and intermediate introns.
Answer:
This promotes the repair response of diseased tissue using stem cells.
Explanation:
It also uses stems instead of donor organs.

The given statements can be matched as following:
a)The diffusion of water from a high concentration to a low concentration - Osmosis
b)Lowers the amount of energy needed to perform chemical reactions
- Enzymes
c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream
-Simple Diffusion
d)Involved with, but does not become a part of chemical reactions
-Enzymes
e)Small molecules with no charge can move through semi-permeable membranes by this process-
Simple Diffusion
Explanation:
a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.
b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.
c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.
d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.
e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.
