I believe animals that possess homologous structures probably evolved from the same ancestor. Homologous structures are similar because of common ancestry. A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor.
Living organisms such as bacteria, fungi, algae are very important in the soil, they perform several functions, some of which include the following;
- Living organisms help break down dead plant parts, this helps to add more nutrients to the soil
- Living organisms dig up holes in the soil, this helps to maintain aeration in the soil.
- Living organisms play a major role on the production of humus
- Living organisms help to break large particles of rock
- Living organisms such as Rhizobium bacteria help in the fixing of nitrogen

Answer: they DO NOT have a nucleus, the don’t have a nuclear membrane. They DO have DNA, nuclear material, a cell membrane. Prokaryotes are less advanced than eukaryotes.
Explanation:
Answer: The correct answer is C) Specialized.
Cells that have their own unique structures and functions are called as specialized cells. These cells are present in multicellular organisms. For performing specific function, they have unique adaptations in their structures.
For example- Nerve cells. They receive and transmit nerve impulses from one part to another part of the body. They are connected to other nerve cells or muscle cells in the body. The typical structure of nerve cell consists of body, dendrite, and exon.
As it performs the specific function, therefore, it is an example of specialized cell.
