Pia mater
<span>Pia mater is a highly vascular tissue that cleaves
firmly to the surface of the brain and spinal cord. Pia mater protects the
central nervous system by nourishing the brain and allowing blood vessels to
pass through it. The inflammation of the pia mater can lead to meningitis</span>

Answer: b. removal of introns from mRNA
The process by which Ribosomes attached to ER or lying freely in the Cytoplasm synthesize proteins from the transcribed mRNA of the DNA is called Translation.
Explanation:
It is made up of three stages;
1. INITIATION;Options C mRNA binding to the ribosome
2. ELONGATION ;Option D joining large and small ribosomal subunits
3, TERMINATION;Option E chain termination at a stop codon
However, Introns are non coding region of RNA base sequence transcribed from the DNA, or sections of DNA encoding the RNA. It is an unwanted part which must be sliced out before translation. Therefore it is not a relevant steps of translation, and hence Option B is the wrong answer.
Note the coded part of RNA trancripts is called EXONS. this the part with the needed information.
Answer:
a. As the temperature rises, the cricket chirp occurs more rapidly therefore increasing. It is correct.
b. As the humidity rises, the cricket chirp frequency occurs more rapidly therefore increasing. It is incorrect. The increase in humidity does not affect the chirp frequency in crickets.
Explanation:
As temperature increases, the frequency of cricket chirp increases too. After listening to the audios, we can see that in the first audio, where the temperature is 14° Celcius, the frequency is 24 chirps in 15 seconds. In the second audio, with 19° Celcius, the frequency is 28 chirps in 15 seconds. In the last audio, where the temperature is 24° Celcius, the chirp's frequency is 34 chirps in 15 seconds. In conclusion, if the temperature increases, the chirps' frequency increases too.
As humidity increases, the frequency of the chirp does not. In the three audios, the number of chirps in 15 seconds was 20. We can conclude that humidity does not affect the frequency of chirps frequency.
