Answer: A. Nervous tissue
Explanation:
The spinal cord, together with the brain, forms the central nervous system and the most important part of the body for the transmission of nerve impulses, that is, information for the functioning of the body. The spinal cord as well as the entire nervous system is made up of nerve cells, whose receptors, neurons, transmit vital information to the brain where they are processed, after which feedback is sent in the form of some kind of command from the brain what certain parts of the body should do, i.e. how to function. In this way, the complete functioning of the organism is regulated. How much to increase the work of a particular organ, glands, how much the heart needs to pump blood, how to move hands, legs, all this is regulated by information from the brain through nerve cells, neurons.
If nerve cell damage occurs, which can be a result of physical injury, or a disease that causes nerve cell disruption, then there is no way to send information to the brain and feedback from the brain, which causes paralysis of certain parts of the body, sometimes the whole body, dependent on the injury and the degree of damage to nerve cells, neurons.
Well first off every thing will be more expensive because we will have more money since we are not using it to buy food any more. we would get more money, save more money, and every thing will cost a lot more. Many people will lose jobs because they won't be making food any more (like people at mcdonalds) and then to get a job people will need higher intellect. The population of cows, pigs, and other animals that we eat will rise and they won't be domesticated any more (unless you want to keep a pet chicken, thats fine with me) and the evolution line might change. Then the downside is that the people live in a climate where it is mostly cloudy and dark will be more hungry and will probably move to warmer areas where they can get enough food. People in warmer climate can just sit outside for a few hours and they will be full and not hungry. As you can see if people began to use photosynthesis to get food. many things will change.
I hope this helped. :3
