Answer:
3. the absence of a cell wall in human cells
Explanation:
Animal cells do not have cell walls. Cell membranes separate the cytoplasm of the animal cells from the surroundings and maintain their interior. Plant cells have cellulosic cell walls. A cell wall surrounds the cell membrane of a plant cell. Cell walls serve to provide structural support and protect plant cells from pathogens. Cell walls also help keep excess water out of cells so they do not burst. Therefore, human cheek cells would not have cell walls while the onion cells would have cell walls made up of cellulose.
Answer:
The correct answer is - C. protein.
Explanation:
Ribosomes are biological molecules that are made up of RNA and proteins. These molecules produce protein molecules with the help of mRNA by the process of translation. These molecules are called the factory of protein or protein synthesis site.
The RNA that is present in these molecules is ribosomal RNA. These are attached to the other cell organelles called endoplasmic reticulum used the protein to check and modify them.
Osmosis! Osmosis is the process that water diffuses across the plasma membrane.
