It has been repeatedly tested and is widely accepted.
We have two parts working for our central nervous system. The brain: it serves as the main control of the human body, it receives information from our senses and provides reaction. The spinal cord: this play a vital role to distribute all neurons throughout, it serves as a connection to provide transmission.
Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.
Answer: c. The overuse of renewable resources can lead to problems similar to those associated with the use of nonrenewable resources.
Renewable resources are those resources, which can be replenished after once used such as wind, water, sunlight and others. Non- renewable resources are those resources, which cannot be replenished after once used, for example fossil fuels like coal, petroleum and natural gas.
Although, renewable resources are abundantly available in nature but their judicious use is necessary, so that these resources can meet the needs of the future generation, ensuring sustainable development of human society. But, in reality the overuse of renewable resources can lead to problems similar to those associated with the use of nonrenewable resources. This is because of increasing population and pollution in the environment, has deteriorated the quality and decreased quantity of renewable resources.
