Answer: 6. Although most invertebrates have a nervous system, the complexity of the system varies from one organism to another.
Some invertebrates such as the hydra and starfish have a simplified system of nerves, which is called a nerve net. It consists of just nerves, capable of sense and touch only. Meanwhile, other invertebrates such as the planarian have a more developed nervous system, complete with a brain and nerve cord.
7. Radial symmetry and bilateral symmetry are two different types of biological symmetries found in organisms. ... The key difference between radial and bilateral symmetry is that radial symmetry generates identical body halves around the central axis whereas bilateral symmetry generates only two sides as left and right.
Explanation:
The relaxed form of DNA in a cell's nucleus is called chromatin.
<h3>CHROMATIN:</h3>
- Chromatin is a complex of DNA and histone proteins within the cell's nucleus. The DNA is too long to fit into the cell's nucleus, hence, is coiled around proteins called histones.
- This complex forms the structure called chromatin, which then condenses during the prophase stage of cell division to form a more compact structure called chromosome.
Therefore, it can be said that the relaxed or uncondensed form of DNA in the nucleus of a cell is called chromatin.
