Classical Biotechnology methods include: Selective Breeding, hybridization, and induced mutations, and recombinant DNA.
Multicellular organisms need specialised organ systems, whereas all the life processes in a unicellular organism take place in that one cell. Multicellular organisms need organ systems to carry out functions such as: Communication between cells, eg the nervous system and circulatory system.
<h3><u>Answer;</u></h3>
Coelom
Animals with 3 issue layers may be characterized by the presence or absence of a <u>Coelom</u>.
<h3><u>Explanation</u>;</h3>
- Animals may be characterized by the presence of a coelom, formation of the mouth, and type of cell cleavage during embryonic development.
- Diploblasts contain two germ layers that is the inner endoderm and outer ectoderm, while triploblasts contain three germ layers, that is; endoderm, mesoderm, and ectoderm.
- <em><u>Triploblasts can be further categorized into those without a coelom called acoelomates, those with a true coelom called eucoelomates, and those with “false” coeloms known as pseudocoelomates.</u></em>
