Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
I cannot find the propositions if it is a MCQ, so I will tell what a bacterial mutualism is:
Mutualism is an exchange between species (two or more) in which the mixed organisms profit from this exchange. Unlike commensalism, the associated species adapt, because the modification of one can affect the survival and reproduction of the affiliated species.
Many mutualistic bacteria live and develop in us, for example, the intestinal flora synthesizes vitamin K, a vitamin that is necessary for the absorption of our food. This same intestinal flora also hinders the proliferation of pathogenic bacteria as well as that of commensal bacteria potentially dangerous.
The answer is C I did it on a quiz and got it right
Answer:
Both of them have developed tissue system. Both of their cell are Eukaryote Mitochondria and other cell organisms are found in both
The peptide bond is formed. The peptide chain is in the P site and at the A site, the next amino acid (specified by the codon on the mRNA) is brought by the tRNA -
1. the polypeptide in the P site is detached from its tRNA and a peptide bond is formed between the last amino acid of the polypeptide and the amino acid attached to the tRNA in the A site.
This is catalyzed by a ribozyme.
