The pleasure and the reward centers of the brain are control by the neurotransmitter known as dopamine. Besides this, the emotional responses and the movements of a person are also controlled by dopamine.
The reward response from eating ice cream is related to the nucleus accumbens part of the brain. The nucleus accumbens is a part of the basal forebrain, present in each of the brain hemispheres. The dopamine neurons in the VTA (Ventral tegmental area) are activated when the activity such as eating ice cream occurs. These neurons are projected into the nucleus accumbens, and their activation gives a feeling of pleasure.
Hence, the answer is 'nucleus accumbens'.
When an object falls, its gravitational potential energy is changed to kinetic energy. You can use this relationship to calculate the speed of the object's descent. Gravitational potential energy for a mass m at height h near the surface of the Earth is mgh more than the potential energy would be at height 0.
Answer:
Explanation:
It is made of flexible but strong tissues of granular cells. They are thick tissues so they don't tear down.
Answer:
Detail is given below.
Explanation:
First of all we will understand the pH.
pH:
pH is the negative log of hydrogen ion concentration.
pH = -[logH⁺]
It means when the ions concentration increases pH will be low and when H⁺ concentration ions decreases pH will be greater. The pH range is 0-14.
If the pH is 7 the solution is neutral, if it is less than 7 the solution will be acidic and above 7 the solution is basic.
when CO₂ is added with water carbonic acid is formed and yield H⁺ ions which decreases the pH thus its color changes from red to yellow just like phenolic indicator. When phenol red is added into the acidic solution the color changes from red to yellow.
and when carbon dioxide is take off from photosynthesis process it means H⁺ ions are going to be decreased thus color changes from yellow to red.
Collisions between all molecules increase as temperature increases. This is due to the increase in velocity and kinetic energy that follows temperature increases. ... This results in more molecules reaching the activation energy, which increases the rate of the reactions.
