Answer:
yes
Explanation:
Nucleosomes fold up to form a 30-nanometer chromatin fiber, which forms loops averaging 300 nanometers in length. The 300 nm fibers are compressed and folded to produce a 250 nm-wide fiber, which is tightly coiled into the chromatid of a chromosome.

Answer: C. The population size became limited due to factors such as availability of food.
Explanation:
Out of all the choices, C is the most likely to happen since more often then not, food runs out because a species has too many members. C is an example of the environment’s carrying capacity limiting the chipmunk species.
Since we are not told if the chipmunk population is really small, interbreeding may not happen. Predators hunt prey, not eat fruits like chipmunks do (I’m assuming what chipmunks eat.) If there was a predator species that came in, they would hunt the chipmunks instead of competing for the same resources. D just doesn’t make much sense in my opinion because that wouldn’t limit the chipmunk population.
Answer:
Statements that are true are:
B) in splicing, intron sequences are removed from the mRNA in the form of lariats (loops), and are degraded = TRUE
C) one mRNA can sometimes code for more than one protein by splicing at alternative sites = TRUE
E) splicing occurs while the mRNA is still in the nucleus = TRUE
Statements that are false are:
A) splicing occurs while the mRNA is attached to the nucleosome = FALSE
D) splicing of mRNA does not involve any proteins = FALSE
