Answer:
Red blood cells.
Explanation:
Our blood is made up of blood cells and plasma which is an aqueous fluid. Blood type is determined by the identifiers presence and absence which is present on the surface of red blood cells. These identifiers are known as antigens which helps in the immune system to identify its own red blood cell types.
There are 4 types of blood type:
A, B, O, and AB. These blood types are determined with the help of the antigen which is present on the surface of the blood cell and antibodies which is present in the plasma.
Frameshift mutation affects codons downstream the point of mutation. The previous order of 3 nucleotide- sequences (codons) is consequently changed. This, therefore, changes the protein coded by the mRNA transcribed by the mutated DNA region. Frameshifts are mostly due to insertion or deletion mutations.
Answer:
Strong hydrologic connections among terrestrial and inland aquatic realms exist in both river floodplains and dryland ecosystems. In the evolution of river floodplains terrestrial vegetation diversifies inland aquatic habitats, providing a range of colonization options for different organisms
