Correct Answer: D) Pulp cavity

Explanation

The question is asking about a specific part of a tooth. The options are Root, Enamel, Dentine, and Pulp cavity. To answer the question, we need to understand the structure of a tooth. A tooth has three main parts: the crown, neck, and root. The crown is the visible part of the tooth that is covered by enamel, which is a hard, protective layer. The neck is the part of the tooth that connects the crown to the root. The root is the part of the tooth that is embedded in the jawbone and is not visible. The part of the tooth that contains blood vessels and nerve fibres is called the pulp cavity. The pulp cavity is located in the centre of the tooth and extends from the crown to the tip of the root. The pulp cavity contains blood vessels and nerve fibres that supply nutrients and sensation to the tooth. Therefore, the correct option in this question is option D, Pulp cavity. It is important to understand the different parts of a tooth and their functions in order to maintain good oral hygiene and prevent dental problems.

Correct Answer: C) mitosis

Explanation

The question is asking about the basis for growth and asexual reproduction. In other words, what process is responsible for an organism getting bigger and making more of itself without the need for sex? The options are meiosis, cytokinesis, mitosis, cytogenesis, and cell elongation. Meiosis is the process by which sex cells are produced, so it is not responsible for growth or asexual reproduction. Cytokinesis is the process by which the cytoplasm of a cell is divided into two daughter cells during cell division. While cytokinesis is important in cell division, it is not the basis for growth or asexual reproduction. Mitosis, on the other hand, is the process by which a single cell divides into two identical daughter cells. This is the basis for growth as cells divide and make more cells. Mitosis is also responsible for asexual reproduction in some organisms, as they can reproduce by budding or fragmentation, which are both types of mitosis. Cytogenesis is not a known process in biology. Cell elongation is a process that occurs during growth, but it is not the basis for growth or asexual reproduction. Therefore, the correct answer to the question is option C: mitosis. Mitosis is the process responsible for growth and asexual reproduction in many organisms.
