The function of protein that helps chemical react is catalyzing
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
I would guess that the answer would be :'<span>These organisms dig more shallow burrows than they used to.</span>' If the crabs actively dig burrows, as many crab species do, and a layer of oil has persisted in the lower soil strata, it makes sense that the crabs would be reducing the depths of their burrows to avoid contact with the oil. The other possibility is that the crabs might might migrate to deeper waters, but this is less likely because the crabs would be evolved to utilise the intertidal zone.
