Answer: The correct answer is- C) Ribosome.
Ribosome is a specialized cellular machinery ( made up of ribosomal RNA and proteins), which is present in both prokaryotic and eukaryotic cells.
It acts as a site for the process of protein synthesis as it reads the codon sequence ( a sequence of three nucleotide in mRNA that codes for an amino acid) present in mRNA ( messenger RNA) and utilizes it in the process called translation ( formation of protein from mRNA).
As per the specific codon sequence of the mRNA, it links the corresponding amino acids together, which results in the formation of specific protein ( polypeptide).
Thus, option C) is the right answer.
Answer:
A) Peptidoglycan
D) Lipopolysaccharide
Explanation:
Gram-negative bacteria have a cytoplasmic membrane, a thin peptidoglycan layer, and an outer membrane containing lipopolysaccharide. There is a space between the cytoplasmic membrane and the outer membrane called the periplasmic space or periplasm.
Answer:
Means to increase drag and prevent sinking is the correct answer.
Explanation:
Plankton avoid sinking by increasing their surface area and decreasing their density. Spines slow down sinking by adding surface area without increasing density. Defense against predation would be to sing below. Not the opposite.
I believe it’s A. Precipitation
