The appropriate response is Mitosis. Amid mitosis, the chromosomes, which have just copied, consolidate and append to shaft filaments that draw one duplicate of every chromosome to inverse sides of the cell. The outcome is two hereditarily indistinguishable little girl cores. Whatever is left of the cell may then keep on dividing by cytokinesis to deliver two little girl cells.
The liverworts are a group of simple plants which are flowerless, spore producing plant.Their spores are produced in small capsules.
An example of liverwort is :

The temperature insensitive, thermostable, DNA polymerase was extracted from a bacterium found in hot springs can withstand the high temperatures needed to separate the double stranded DNA and the replication process can continue uninterrupted. The enzyme thermus aquaticus can withstand the high temperature used to separate double stranded DNA, so replication does not need to be interrupted by the need to add more enzymes.
Answer:
option A
Explanation:
The protein specific sequence also known as the primary sequence is determined by the sequence of its amino acids linked together by peptide bonds. The sequences of amino acids determine the proteins that will eventually be synthesized. This proteins becomes functional when correct folding pattern/ native conformation of the protein occurs which determines the shape of the proteins. peptide bonds hold the amino acid sequences together, hydrogen bonds involving components of the peptide bonds allow for the existence of the secondary structure either the alpha helix or the beta pleated sheets and then disulphide bonds and other type of bonds helps in the folding of the protein to become a functional protein.
Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body.
The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
It also includes chemical barriers such as mucus, gastric acid, bile, tears, sweat, and saliva.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera.
Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.
