Answer:
You tell her that this is incorrect.
Explanation:
The given information is incorrect as both small and large ribosomal subunits are required for protein synthesis. The eukaryotic ribosomes have E, P, and A sites. The A and P sites bind to the aminoacyl tRNA that carry the amino acid encoded by the codon of the mRNA.
The formation of peptide bond occurs between the amino group of amino acid in A site and the carboxyl group of amino acid present on P site. Both 40S and 60S subunit of ribosome contribute the A and P sites.
Answer:
Neurons are similar to other cells because neurons have a cell membrane, a nucleus, cytoplasm, mitochondria, organelles, and carry out processes such as energy production.
Neurons differ from other cells because neurons have extensions called axons and dendrites, they communicate with each other through an electrochemical process which we just talked about, and neurons have specialized structures such as synapses and chemicals such as neurotransmitters.

Answer:
a. Osteogenic cells can differentiate into osteoclasts
Explanation:
Osteoblasts are the cells that are formed from osteogenic cells. The osteogenic cells enter the process of bone formation. There is a secretion of organic compounds and salts to form osteoblast. Osteoclasts are the very large cells that are formed when many monocytes fuse together and are concentrated in endosteum. Osteoclasts are the cells responsible for bone resorption.
Answer:
e. infection causes lymphocytes to divide more rapidly
Explanation:
The cell cycle includes interphase and M phase which in turn together produce daughter cells from the existing parent cells. DNA replication occurs during the S phase of interphase to ensure that the daughter cells obtain the identical DNA present in the parent cell.
Lymphocytes are one of the types of white blood cells and are involved in cell-mediated and antibody-mediated immune responses. These cells are present in the blood as well as in lymphatic tissues. During the given experiment, lymphocytes exhibited a higher rate of incorporation of labeled nucleotide after the introduction of a pathogen in the culture. This suggests that the introduction of pathogen triggered the cell division in lymphocytes to produce more lymphocytes to fight the infection.
