Answer:
Option B, atom - molecule - organelle - cell - tissue
Explanation:
Atom is the smallest unit in any living being structure. A group of atoms combines to form molecules. A group of molecules combine to form an organelle. An organelle is a small cellular structure that is found with in a cell. Thus specific group of organelles grouped together form cells. A group of cells arranged in specific manner and specialized in specific function forms the tissue.
Hence, option B is correct.

The fossil records that scientists has used understand human evolutionary patterns include the following. Ardipithecus ramidus bones that revealed advances in upright walking, even tough they had a small brain that measured between 300 and 350 cm3. Australopithecus lack of an opposable big toe suggest that they lived on the ground instead of in trees. Homo erectus was the first species to use and control fire, as suggested by evidence of microscopic traces of wood ash.
An enzyme's shape is determined by the sequence of amino acids in its structure, and the bonds which form between the atoms of those molecules. ... Different types of enzymes have different shapes and functions because the order and type of amino acids in their structure is different.
Denature means to destroy the characteristic properties of (a protein or other biological macromolecule) by heat, acidity, or other effect which disrupts its molecular conformation.
