Answer:
Cytotoxic T cells
Explanation:
Perforin is the cytosolic protein and upon degranulation forms pores in the target cell. Perforin protein helps in the transport of water and ions.
Perforin is present in the granules of cytotoxic T cells. These cells have the ability to kill virus infected cells and cancer cells. Cytotoxic T cells bind with the class 1 MHC molecules. These cells are also known as CD8+ T cells.
Thus, the correct answer is option (A).
Answer:
The order of bonds in increasing order of bond strength would be Ionic, peptide, polar covalent, non-polar covalent hydrogen bond.
Ionic bonds are the strongest bonds which are formed by transferring of valence electrons between different atoms. For example, a bond between sodium and chlorine atoms in NaCl.
A peptide bond is a type of covalent bond formed between a carboxylic group of one amino acid and the amino group of another amino acid. It is provided with extra stability through resonance.
A covalent bond is a type of bond which is formed by the sharing of electrons between two atoms.
They bond strength of these bonds is less than that of ionic bonds and more than that of hydrogen bonds.
Hydrogen bonds are weak bonds formed through electrostatic interactions between a proton present in one molecule and an electronegative atom in another molecule.
The answer would be the Oceans because water makes up a very large portion of the earth in general.
Hope this helps!!
Answer:
Scientific law is a description of an event. Scientific theory is the explanation for that event.
Explanation:
Or in better words, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation for a phenomenon is called a scientific theory
