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).
C. Movement of the human body
Skeletal muscles gives us the ability to move
The Mungo Man was discovered by ANU archaeologist Dr. Jim Bowler on ... This made Mungo Lady the oldest cremated human remains yet discovered.Thorne claims that the findings support his theoretical point of view.Evidence - Mungo Man's skull.Two years ago Thorne made world headlines with a study of Mungo Man's DNA that he had found.
An ionic bond results in an exchange or transfer of electrons between the 2 different types of atoms, most likely the metal atom and nonmetal one.
For example the compound NaF is held together by electrostatic forces of positive and negative charges due to the transfer of electrons from the sodium to fluoride atom.
All the statement above are very true of what virus structure constitute.
This goes to say that viruses:
- use DNA as their genetic material.
- have a phospholipid bilayer envelope.
- lack organelles, ribosomes, and a plasma membrane.
- have a capsid.
- require a host for replication.
<h3>What are viruses?</h3>
Viruses are seen and considered as the border line between living and non living things.
- Viruses are living when they are inside another living organism. They are the smallest known microorganisms.
- However, they are non-living when they are outside the system of a living thing
