Saturated fatty acids are chains of single bonded carbons surrounded by hydrogen atoms.
Unsaturated fatty acids have bent structures due to double bonding between carbon atoms in the chain. When carbons create double bonds with each other they are no longer able to hold as many hydrogens as a saturated fatty acid
Answer:
Round
Explanation:
The Earth is round ,even though there are many contradictions. The Earth spins on an axis, which is why there are different time zones all around the world. If the world was flat, then an Earth's core wouldn't exist and also the laws of gravity would not make since due to the Earth being considered flat. People would never know if they met the end of the Earth, or if they walked off the face of the Earth. Also note that if the Earth was flat then our Solar System would have to be flat since it involves the planets to revolve around the Sun.
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.
B. The prefrontal cortex is used to plan complex cognitive behavior, personality expresison, and moderate social behavior.
