Answer:
Explanation:
The barnacles are only able to attach themselves to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.

Answer:
<em>make a gene from the given mRNA without the introns.</em>
Explanation:
Introns can be described as the non- coding regions of DNA. As they are non- coding, they are spliced out from the mRNA so that only the coding regions can be translated.
If we know a nucleotide sequence, then we can make a gene from it without added the introns. We can consider an mRNA strand and make a complementary strand from it, excluding the intron regions. Then from the DNA produced, we can make an mRNA without the introns and insert it into a bacterium.
The lungs work by expanding and going back to their original size when you inhale and exhale. The rib cage also expands so the lungs can have more air inside and expand. Due to deformities, the rib cage might not expand and/or the diaphragm might not lower itself, which might lead to pressuring the lungs not to expand and having a lower volume of air inside. This leads to breathing difficulties.
