Answer:
The Pepsi he drinks at 10 pm
Explanation:
Pepsi is a caffeinated drink that has caffeine in it. Caffeine is a stimulant which means it keeps the body awake and alert. Caffeine works by mimicking adenosine. Adenosine is produced by neuron cells and when it binds to its own receptors (autocrine signaling) it triggers the neurons cells to continue firing. As the adenosine levels fall as the day progresses, the brain is signaled that it is time rest. Adenosine levels are at the lowest when its almost bedtime. However, when Jon takes Pepsi, the caffeine in it bind to the adenosine receptors and make the brain neurons to keep ‘firing’.
Answer:
6. Because of how old the rocks are
Explanation:
6. Sedimentary rock forms in layers because of the order they were formed. The older rocks will form first and as time goes on, rock forms above it to create a new layer, and so on.
This means that the mothers green eyes are recessive alleles and the fathers brown eyes are dominant alleles. The blue eyed puppy is blue eyed because there must have been a gene in the mothers or fathers past generation.
- Thermosphere - Fourth layer of Earth's atmosphere.
- Aurora Borealis - Ionosphere layer of thermosphere.
- Large-scale air turbulence and mixing at this layer - Troposphere
- Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
- The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
- Maximum ozone - Ozone layer in Stratosphere
Explanation:
Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.
1. Troposphere -
- The first layer of the atmosphere.
- Weather occurs in this layer.
2.Stratosphere -
- The second layer of Earth's atmosphere.
- Contains Ozone layer.
3. Mesosphere -
- The third layer above the stratosphere.
- Coldest layer.
4. Thermosphere -
- The fourth layer of the atmosphere.
- Warmest layer.
- Ionosphere - lowest level of thermosphere above mesosphere.
- Aurora Borealis, Northern and Southern lights are seen in this layer.
- Exosphere - outermost layer of thermosphere.
- Satellites are in this layer.
- Outer space with no gravity.
