Explanation:Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Hox genes, which are members of the homeotic transcription factor family, establish the segment identity of tissues within the embryo and are essential regulators of the body plan along the cranio-caudal axis (also known as the anterior-posterior axis). This means during embryogenesis, these genes expression follows a precise spatial and temporal colinearity pattern from the 3' to the 5' end of each cluster.
This indicates that Hox genes expressed anteriorly in the developing embryo are typically found at the 5′ end of the same genomic area, a phenomenon known as spatial colinearity. In comparison, those expressed posteriorly are typically found at the 3′ end of the Hox cluster.

Answer:
Species accumulate their unique features rapidly, then change little for the duration of the species.
Explanation:
The general area of the body that the cranial nerves serve are the HEAD AND NECK organs.
Here are the list of the 12 Cranial nerves together with its function.

Solar Energy is best option of Coal power plant. It is safe as well as very minimal impact on environment.
Explanation:
Solar energy is one of the best ways to build an energy. It uses captured sunlight and create photovoltaic power or “concentrated solar power” for solar heating. The use of solar power is increasing day by day.
Now subway, buses, college, institute all use solar energy for their electricity consumption. Recently solar powered aircraft whose name is impulse2 is made. Because of zero emission of carbon dioxide government move towards this option.
Disadvantage: It is very costly and takes more space for installation
