GENERAL HISTOLOGY

Detailed explanation-1: -The answer is B. All living things are made of cells and come from other cells. The other options would not be possible since not all of living things have chloroplasts, hair and not all living things can move because some living things are motile.

Detailed explanation-2: -Living things can be found in every type of habitat on Earth-on land and in lakes, rivers, and oceans. Although all these organisms are very different from one another, they all have two things in common: they are all descended from a single ancient ancestor, and they are all alive.

Detailed explanation-3: -Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits.

Detailed explanation-4: -The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory.

Detailed explanation-5: -A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular). Cell biology is the study of cells, their physiology, structure, and life cycle.
