If only nuclear division occurs without cytokinesis during the process of cell division, the result would be the formation of multinucleated cells or cells with multiple nuclei.

Cell division consists of two main processes: nuclear division (mitosis) and cytoplasmic division (cytokinesis). During nuclear division, the nucleus of the cell divides, ensuring that each daughter cell receives a complete set of chromosomes.

On the other hand, cytokinesis involves the division of the cytoplasm, resulting in the separation of the two daughter cells.

If only nuclear division occurs without cytokinesis, the cell would undergo mitosis but not divide into two distinct cells. As a result, the daughter cells would share a common cytoplasm, leading to the formation of multinucleated cells or cells with multiple nuclei. These multinucleated cells are known as syncytia.

Syncytia can be found in various biological processes and tissues. For example, muscle fibers are multinucleated cells formed by the fusion of multiple precursor cells during development. Similarly, certain fungal hyphae and giant algae cells can have multiple nuclei due to incomplete cytokinesis.

In summary, if only nuclear division occurs without cytokinesis, the cell would produce multinucleated cells or cells with multiple nuclei, where the daughter cells remain connected by a shared cytoplasm.

Answer:

80°C

Explanation:

The change in temperature can be calculated my using the specific heat capacity equation as follows;

Q = m × c × ∆T

Where;

Q = amount of energy (J)

m = mass (kg)

c = specific heat capacity of water (J/kg°C)

∆T = change in temperature (°C)

According to this question, Q = 201,600J, m = 600g = 600/1000 = 0.6kg, c of water = 4200J/kg°C

Using Q = m × c × ∆T

201600 = 0.6 × 4200 × ∆T

201600 = 2520 × ∆T

∆T = 201600 ÷ 2520

∆T = 80

Change in temperature (difference in initial and final temperature) is therefore 80°C

The part of the tooth that contains a rich supply of nerves and blood vessels is called the dental pulp.

The dental pulp is a soft, connective tissue located at the center of the tooth, occupying the pulp chamber and extending into the root canals.

The dental pulp plays a vital role in the health and function of the tooth. It is composed of a network of blood vessels, nerves, and connective tissue cells, including odontoblasts, which are responsible for producing dentin, the hard tissue that forms the majority of the tooth structure.

The dental pulp has several functions. It provides nutrients and oxygen to the tooth through its blood vessels, ensuring the vitality of the surrounding hard tissues.

The nerves within the dental pulp are responsible for transmitting sensory information, including sensations of pain, heat, and cold. This allows us to perceive different stimuli and respond accordingly.

In addition to its sensory and nutritive functions, the dental pulp has a role in tooth development and repair. During tooth formation, the dental pulp interacts with the cells responsible for enamel and dentin formation, contributing to the growth and maturation of the tooth structure.

Furthermore, in response to injury or decay, the dental pulp can initiate a reparative process by forming secondary dentin as a protective response.

It's worth noting that the dental pulp is often protected by the outer layers of the tooth, including the enamel and dentin. However, when the dental pulp becomes infected or inflamed, it may require dental treatments such as root canal therapy to remove the diseased tissue and preserve the tooth's function.
