Answer:

In higher vertebrates the internal fluid of the inner ear (not external fluid as in fish) bathes ... The pinna and external auditory meatus collect these waves, change them ... 12.3 The Cochlea: three scalae, basilar membrane, movement of hair cells ... frequency sounds stimulate the base of the cochlea, whereas low frequency ...

The most primitive true animal belongs to the phylum ____.
VMariaS [17]

Answer:

Porifera or Sponges

Explanation:

Porifera is the phylum of the simplest multicellular marine animals. Their body is composed of  two cell layers (something like tissues) and mesophyl between them. The body is in direct contact with surrounding water through the large number of pores and channels. What makes Sponges so simple is that their cells are unspecialized and that they  don't have nervous, digestive or circulatory systems.

When RNA is processed in the nucleus and made ready for transfer out into the cytoplasm for protein synthesis, which of the foll
IRISSAK [1]
Answer:
Letter E - exons are cut from the strand and removed

Explanation:

Letter A and B are incorrect because the poly-A tail and guanine cap are added to the 3’ and 5’ end respectively. They aid in translation of the mRNA, while serving as protection. The poly-A tail is repeated adenine nucleotides, while the guanine cap is a modified guanine nucleotide.

Letter C is incorrect because alternative splicing is one mechanism for generating variation, and is thought to be one of the reasons for why humans have smaller genomes than other organisms and still maintain high complexity. Alternative splicing is incredibly important because it produces more than one transcript from a pre-mRNA.

Letter D is incorrect because introns are the non coding portions of the mRNA. They are excised to make a smaller mRNA transcript, and one that contains all the protein genes.

This letter E is the correct answer, because exons are the coding portions of the mRNA, and are not excised during RNA processing.

Hope that helped! If I made a mistake, please let me know.
