Answer:
A
Explanation:
Living organisms adapt to their moves and positions in response to the environmental changes for their protection or to their advantage. When an entity reacts to the changes in its surroundings, it is referred to as stimulus while the reaction to the stimulus is referred to as a response. Common stimuli are sound, light, air, heat, smell, taste, water and gravity.
Think of burning your finger of fracturing your bone without any pain sensation. It may certainly sound like a superpower or an ideal situation, however, when it comes to the standpoint of survival, it can be disastrous.
It is a characteristic behaviour of living entities to respond to stimuli with the intervention of the Nervous System. It is an organ system ascribed to send signals from the spinal cord and the brain throughout the body and then back from all the body parts to the brain. Neuron acts as the mediator and is the basic signalling unit of the Nervous system.
Pain is the body’s way of letting us know that something is not right. It can prevent further injuries or push us to seek medical attention. Moreover, all of this is possible because humans can respond and react to stimuli due to control and coordination among the various organs and organ systems.
Control and Coordination in simple multicellular organisms take place through only the Nervous system which coordinates activities of our body. It is the control system for all our actions, thinking, and behaviour.
Answer: asked the patient two questions about feelings of hopelessness and feelings related to the enjoyment of activities
Explanation:
Hopelessness is an emotional context featured by a lack of hope, passion, and optism. It is expressed as a symptom of varying behavioral and mental health problems, including depression, bipolar, anxiety, eating disorders and among others.

Coal mainly came from decomposition of plants for a long time and oils as well as natural gases are mostly found in ocean environments.
Answer:
c. to account for two major and distinct prokaryotic groups in addition to eukaryotes.
Explanation:
Microbiologist Carl Woese compared the ribosomal RNA sequence of the small subunit of RNA. Various organisms have structurally different small subunit of the ribosomes. According to Woese the molecular composition of rRNA in closely related organisms should be more similar than in distantly related organisms. He analyzed the 16S rRNA of various organisms and observed that there are two distinct groups of prokaryotes. He divided the prokaryotes among two domains: Bacteria and Archaea. He placed all the eukaryotes in the domain Eukarya.
Because of its ability to form large complex and diverse molecules
