Why does your respiration increase during exercise?
Answer:
Explanation:
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

Differentiate between the layers of the Earth based upon physical properties AND explain the flow of heat within and between the layers of the Earth.
Answer:
The Earth can be divided into 5 main layers according to their physical properties: the lithosphere (most superficial layer of the Earth: rigid and cold), the asthenosphere (Second most superficial layer of the Earth: soft and ductile), the mesosphere or lower mantle ( Middle layer of the Earth: rigid and hot, able to flow gradually), the outer core (Second innermost layer of the Earth: liquid) and the inner core (innermost layer of the Earth: solid). The flow of heat inside the Earth will depend on the temperature and the characteristics of the material. The crust behaves like a solid and has relatively low temperatures. The mantle behaves like a fluid and since convection is much more efficient in this case, that is the main means of transport, even though the relatively high temperatures make it possible for energy to also be transported by means of radiation.
Explanation:
As you descend into the Earth's interior, the temperature, pressure, and density of the rocks gradually increase. The Earth can be divided into five main regions based on its physical properties (temperature and pressure) and according to its mechanical resistance: lithosphere the chemical composition of this layer is notably different, it also acts as a unit that shows a rigid behavior (not can be bent), mainly because it is cold and consequently resistant, asthenosphere located in the upper mantle (at a depth of about 660 km), there is a comparatively plastic soft layer, mesosphere (lower mantle) more rigid layer and it is because as the pressure increases, it counteracts the effects of the higher temperature and the resistance of the rocks increases gradually with depth. Despite their resistance, the rocks of the mesosphere are still very hot and are able to flow in a very gradual way, the outer core is a 2270 km thick liquid layer. The convective currents of iron in this area are those that generate the Earth's magnetic field and the inner core of the material is more resistant than the outer core (due to the enormous pressure to which it is subjected) and behaves like a solid. When penetrating the crust of the Earth a change in temperature is observed, in general it increases; this variation in temperature with depth is called a geothermal gradient. The heat flux on the Earth's surface is calculated as the product of the geothermal gradient and the thermal conductivity of the rocks, these two parameters being directly determined. The Earth is basically made up of three concentric layers: the innermost core has a composition of cast iron at a temperature of over 4,000 ºC; the mantle that is the intermediate layer formed by iron and magnesium silicates and its temperature varies from 4,000 ºC in its contact with the core to 800-1000 ºC of its outer surface that contacts the crust that is the most superficial layer and visible by man. This crust has a variable thickness of 5 to 35 km and is made up of aluminum and magnesium silicates, its temperature varying between 800-1000 ºC of contact with the mantle and 15-20 ºC of the surface that we know.

What is the difference between primary waves and secondary waves
Answer:
Primary and secondary waves both are body waves of seismic waves. Primary waves or pressure waves are compression waves and secondary waves are shear waves. These waves are represented by P and S waves respectively.
Differences:
P waves are smaller in size but travel faster, however, cause less damage whereas S waves are greater in size cause more damage, and travel slower.
P waves move in a push-pull pattern and travel through different mediums like solids, liquids, and gases, whereas S waves move in an up-and-down pattern and travel only through one medium that is a solid medium.

26. What about the structure of a fat molecule makes it useful for a cell and why?
The large number of carbon-hydrogen bonds allow for the storage of energy.
Fats serve as enzymes in the process of digestion.
The glycerol portion of the fat molecule is used to release energy
The fatty acid part of fats help digest food in cellular respiration.
the large number of carbon-hydrogen bonds allow for the storage of energy
The structure of a fat molecule makes it useful for a cell, and a large number of carbon-hydrogen bonds allows for the storage of energy. The correct option is a.
What is the structure of fat?A glycerol backbone and three fatty acid tails make up the two types of components that make up a fat molecule. It contains a glycerol molecule and is a little chemical molecule. Where the hydroxyl group occurs in the groups, there are three fatty acid tails.
They have a long hydrocarbon chain since that is what they are. This particular long hydrocarbon chain has a carboxyl group or oxy group attached due to the abundance of carbon-hydrogen bonds.
Energy can be stored in it. On the structure, it is excellent for storing energy. Energy can be stored in a specific structure.
Therefore, the correct option is a. Numerous carbon-hydrogen bonds to allow for the storage of energy.

During a large thunderstorm, you hear and feel the thunder. Draw a representation of the sound wave produced. Your model should account for the energy and patterns of the wave.
Answer:
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Explanation:
This is why we hear and feel them!
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
What is Sound waves?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disturb the particles next to them, and so on.
Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.
Therefore, Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).

Answer:
It appears that neither would be worse since they both have an equal impact on the ecosystem, not sure if this is an option though, goodluck with your assignment
Answer:
Either, because the removal of either one would have the same impact because they eat the same food and are preyed upon by the same predators.
