No idea but hopefully this cheers you up!
True. If the diameter of the afferent arterioles leading to the glomerulus increases due to vasodilation, which ultimately increases the net filtration pressure.
The filtration of blood occurs in the kidney, an excretory organ. The kidney is composed of numerous small units called nephrons, which is responsible for the blood filtration.
Glomerulus is part of nephron and the glomerular filtration occurs in the renal corpuscle of the kidney. This process is driven by hydrostatic and colloid osmotic pressure.
These pressures are collectively called net filtration pressure, which is influenced by the diameter of afferent arterioles.
If the arterioles constricts, net filtration pressure will decrease and if arterioles dilates, net filtration pressure will increase. This mechanism is regulated by neural, renal and hormonal regulation.

Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
