The lipid bilayer works as a barrier that protects the cell from outside dangers.
C. prevent the passage of certain molecules into the cell
Hope I helped! :)
Answer:
a) 0.1 mL
b) contamination
c) clumping of colonies
d) Uneven colonies
Explanation:
In general, when performing spread plates, 0.1 mL
mL of cell suspension is added to the plate to prevent the formation of a microbial contamination
Adding more than 1 mL of cell suspension to an agar plate will result in a clumping of colonies.
Adding less than 1 mL of cell suspension to an agar plate will result in a Uneven colonies
This could either be c or d, both should work
During transcription process in the nucleus, the information for synthesis of a particular protein is copied on to mRNA.
mRNA then leaves the nucleus with this information in code, and enters the cytoplasm and attaches to a ribosome. Ribosome are the "work benches" of the cell and it is here that proteins are made.
In the ribosome, transfer RNA or tRNA recognizes a triplet of bases e.g. GCA on the attached mRNA and decodes it. This is called the translation process. Once tRNA has determined which amino acid corresponds to that triplet, it fetches that amino acid from the pool of free amino acids in the cytoplasm and into the ribosome where it is linked with other amino acids into a chain to form the protein.
Protista
A protist is any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, since they sometimes exclude certain eukaryotes; but, like algae or invertebrates, they are often grouped together for convenience.
