Answer: In mathematics, a representation is a very general relationship that expresses similarities (or equivalences) between mathematical objects or structures. The label representation is sometimes also applied to the homomorphism itself (such as group homomorphism in group theory).
Explanation: A bit is a binary number in which 0 is typically used to represent off (or false or positive) and 1 is typically used to represent on (or true or negative). Some sample binary ( base 2) numbers are 0, 1, 10, 11, 100, 101, 110, 111, which represent 0, 1, 2, 3, 4, 5, 6, 7 in base 10.
Prokaryote! If u need explanation just ask below
Answer:The difficulty in developing vaccines against parasitic diseases is to identify (and produce) appropriate protective antigens because of the lack of complete understanding of the type of immune response required for protection.
Explanation:
I hope this kinda helps.
Answer:
B. secrete granzymes and perforin.
Explanation:
Perforins are the proteins that perforate the plasma membrane of the target cell and lead to bursting of cells due to holes formed in its membrane. Granzymes are the proteolytic enzymes. They serve to stimulate the target cells to kill themselves by the process of apoptosis.
Binding of natural killer cells to their target cells stimulate the release of granules that are filled with perforins or granzymes to kill the target cells.
Likewise, cytotoxic T cells bind to the infected body cells and release the granules filled with perforins or granzymes to kill those infected cells.
Muscle tissue are specialised for contraction.
