Believers in Christianity are allowed to be named Jesus because it is a common name in many cultures and has historical significance as the name of Jesus Christ, the central figure in Christianity. Similarly, believers in Islam are allowed to be named Mohammed because it is the name of the Prophet Muhammad, who is highly revered in Islam as the final prophet. Both names hold deep religious and cultural significance for their respective faiths, making them permissible choices for believers to be named after. **

Enzymes are named based on the type of reaction they catalyze and the substrate they act upon. The names of enzymes typically end in "-ase" to indicate their enzymatic function. The first part of the name often reflects the substrate or the type of reaction the enzyme is involved in. For example, the enzyme that breaks down lactose is called lactase, and the enzyme that breaks down lipids is called lipase. Additionally, enzymes are often given a systematic name based on their specific function and the biochemical pathways they are involved in. **

Alkanes are named based on the number of carbon atoms in their longest continuous chain. The prefix used in the name corresponds to the number of carbon atoms in the chain (e.g. meth- for one carbon atom, eth- for two carbon atoms, prop- for three carbon atoms). The suffix -ane is added to indicate that the compound is an alkane. Additionally, any branches or substituents on the carbon chain are named using prefixes such as methyl-, ethyl-, etc. **

Constants are typically named using uppercase letters with underscores separating words, for example, MAX_VALUE or PI. This naming convention helps distinguish constants from variables and makes them easily recognizable in the code. Constants are usually given descriptive names that reflect their purpose or value, making the code more readable and understandable for other developers. **

Angles are named based on the relationship between the rays that form them. The most common way to name an angle is by using three points, with the middle point representing the vertex of the angle. For example, an angle can be named as ∠ABC, where A and C are the endpoints of the rays that form the angle, and B is the vertex. Another way to name angles is by using a number or letter to represent the angle itself, such as ∠1 or ∠x. **

No, the firstborn in Islam does not always have to be named Mohammed. While it is a common practice in some Muslim cultures to name the firstborn son Mohammed, it is not a requirement in Islam. Parents are free to choose any name they like for their child, and there is no specific religious obligation to name the firstborn Mohammed. In fact, there are many other names that hold significance in Islam and are commonly used for children. **

Swords are often named after their shape, origin, or the person who made them. For example, the katana is a type of Japanese sword named after its curved, single-edged blade. The rapier is a slender, sharply pointed sword that is named after the Spanish word for "dagger." Additionally, some swords are named after legendary figures or historical events, adding to their cultural and historical significance. **
