Answer:
It processes the environment and sends out signals.
Explanation:
Sense receptors can sense any changes in internal or external conditions which disturb the homeostasis. The sensory information is sent to the central nervous system which in turn process the information and commands the respective body parts to perform actions to restore the homeostasis.

It should be d then genes
Two identical cells are created in meiosis is the correct answer.
Exposing humans to potentially dangerous levels of radiation as used x-rays can be fatal. X-rays are able to denature and mutate genetic molecules such as DNA and RNA, hence it can be described as a mutagen. An ultrasound scan however uses sound to create an image - this involves no radiation and is hence far safer. It is one of the reasons why it is used to examine foetuses and babies when in the uturus. The ultrasound also allows the kidney's topography and underlying structures to be observed.
