Explanation:
In eukaryotic cells, pre-mRNA has to undergo 3 stages of RNA processing before being transported into the cytosol. Specifically during RNA Splicing, small nuclear RNAs (snRNAs), small nuclear ribonucleoproteins (snRNPs) and other proteins form a spliceosome which excises introns and splice together exons. Introns are considered junk material and does not stay with the mRNA.
The answer is Introns. (D)
The correct answer should be: "blocking all solar ultraviolet (UV) radiation."
Hope this helps!
When we are talking of dominance in genes, we have that a gene can present with certain variations, this variations are called alleles. Now acording to mendelian genetics in alleles we can have dominant alleles or recessive alleles.
When an allele is dominant it means thet every time this allele be present the trait thet code will show, it doesn't matter if the organism is homozygous (SS for example) or heterozygous (Ss for example) in both cases the person wil have smile dimples, now a recessive trait will only show itself when is in its homozygous form (ss) and in that case and only the person won't show smile dimples.

Your answer is b. In diffusion, molecules move from high to low area of concentration.
<h2>
Answer:</h2>
Option C) The organism can move around its environment using a flagellum.
<h2>
Explanation:</h2>
Out of four options option C) matches the most.
- Although most of the bacteria are Heterotrophs but a variety of species of them are Autotrophs making their own food. Hence option a) is incorrect.
- Bacteria belong to prokaryotes which means they do not have a well defined membrane bound nucleus. hence option b) is also incorrect.
- Most of the bacteria can move through flagella only a few species do not have flagella. Hence this option matches the most.
- Bacteria are unicellular organism and none of the species of bacteria is multicellular. Hence option d) is incorrect.
Resut: Option C) matches the most for defining bacteria.
