Explanation:
All prokaryotes are single-celled (unicellular) organisms.
Biologists recognize five levels of cell organization. The lowest and simplest is the cellular level. Organisms here are either unicellular organisms, like protozoa, or colonial organisms. Colonial organisms are composed of single-celled individuals that stay together to sustain the life of the whole colony. Next on the scale of complexity is the level occupied by tissue. A tissue is a group of similar cells that perform a similar activity. Tissues that are organized around a common function together make up an organ, the third level of complexity. The fourth level of organization is the system, formed by a group of organs that together perform a specific bodily process. The fifth and highest level is the organism level, in which body systems work together in a structure capable of independent life.
The physiological process occurring in the muscle cells that account for the gradual onset of muscle fatigue is called anaerobic the body is breaking down oxygen after than it can get in.
D. Cones
Cycads are basically composed of woody plants which have roots, a stem, leaves and reproductive structures called Cones. These cones differ from each other depending on the plant whether it is female or male. These cones vary from shape, size, color, etc. based on the sex of the plant.
