The signal will start from the eyes. The message is carried by sensory neurons to the spinal cord. There, the "impulse" will transfer to motor neurons which will carry it to the brain. So in short:
Sensory neurons --> spinal cord --> motor neurons --> brain
Answer:
a.They evade the normal controls that trigger programmed cell death.
Explanation:
Cancer cells are cells in the body that grow abnormal and uncontrollably. Continuous growth cancer cells results in the development of tumor as well as the ability to invade neighboring tissues.
Unlike normal cells that are controlled (reproduce only when needed) and are more specialized with specific functions, cancer cells are less specialized compared to normal cells and grow abnormally and rapidly. Cancers cells grow out of control, as they evade the normal control and ignore signals that activate apoptosis or programmed cell death which is used by the body system to destroy unwanted cells.
Yes. the nucleotides are A, T, G, and C. A and T pair up and G and C pair up. For instance, if your known strand is AGTCAG then the second strand would have to be TCAGTC. Also, if there is a U in the strand, it takes the place of T. so the original strand would be AGTCAG and the unknown would have to be UCAGUC.
