Which statement is one of the three parts of cell theory? the smallest living things are single cells, and cells are the functional units of multicellular organisms. there are three types of cells, prokaryotic, eukaryotic plant, and eukaryotic animal. cells make up tissues, tissues make up organs, organs make up systems, systems make up organisms. cell organelles can be membrane-bound or not membrane-bound.

The smallest living things are single cells, and cells are the functional units of multicellular organisms.

Explanation:

Cellular theory is formed by ideas from Schleiden, Schwann and Virchow. The first two proposed the basis of this theory. Cellular theory can be divided into three postulates:

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

carbon
