Answer: Organism in this domain can be defined as living things that has an organized structure, and responds to stimuli, and has ability to reproduce, grow, and maintain a state of equilibrium. Organisms are of two types which are unicellular and multi cellular organisms.
Explanation: unicellular organisms are organisms that are made up of only one cell which carries out all the functions needed by the oragnism. Multicellular organisms are organisms that are made up of more than one cell. These organisms uses many different cells to function.
Unicellular organisms are often found in extreme environments such as hot springs, polar ice and frozen tundra.
Unicellular organisms have cell that contain a nucleus.

Answer:
Three factors are used.
The availability of sunlight.
The distance from shore and
The water depth.
Explanation:
<u>Availability of Sunlight
</u>
The photic zone is the upper part of the ocean into which sunlight penetrates.
<u>Distance from Shore
</u>
The intertidal zone is the strip of land where the land and ocean meet and overlap, or the zone between high and low tides.
The neritic zone is the marine-life zone that extends from the low-tide line out to the shelf break.
The oceanic zone is the marine-life zone beyond the continental shelf.
<u>Water Depth</u>
The pelagic zone is open zone of any depth. Animals in this zone swim or float freely.
The benthic zone is the marine-life zone that includes any sea-bottom surface regardless of its distance from shore.
The abyssal zone is a subdivision of the benthic zone characterized by extremely high pressures, low temperatures, low oxygen, few nutrients, and no sunlight
<h2>Mitotic Cell Cycle</h2>
Explanation:
a. Cytochalasin: an inhibitor of actin microfilament
- Cytokinesis is the process by which cytoplasm is divided into two cells hence generation of two daughter cells
- In animal cells the division of cytoplasm starts with the assembly of contractile ring
- Contractile band consists of actin and myosin and catalyze cleavage furrow formation
- Cytochalasin is a drug that blocks the polymerization of actin filament
- When cytochalasin is added dividing cell fails to undergo in cytokinesis due to defective assembly of contractile band
b. Colchicine: an inhibitor of microtubule formation
- Colchicine tightly binds with free tubulin dimer and prevents its polymerization
- In this case mitotic spindle apparatus do not assemble and cells unable to do partitioning of chromosomes into two groups
- Thus cell division is arrested
c. Aphidicolin: an inhibitor of DNA Polymerase activity
- Aphidicolin is used to induce cell cycle arrest via specific inhibition of DNA Polymerase α
- It blocks the cell cycle at early synthesis(S) phase
d. Emetine: an inhibitor of ribosome activity
- It blocks the protein synthesis in eukaryotic cells by binding to small subunit(40 S) of ribosomes
- It interferes with the synthesis and activities of DNA and RNA
