If I had been Louis Pasteur, my first reflection would be that the experiment was able to produce milk with longer shelf-life. From there, I would make inferences as to how it happened. I already have knowledge about microorganisms and how they react or degrade with heat and pressure. So, I would conclude that by subjecting the milk to that specific temperature and pressure, the microorganisms that cause spoilage are destroyed.
Later on, I would also realize that it's not only the spoilage-causing bacteria that are destroyed but also all the other microorganisms present in the milk examples of which are probiotics.
Answer:
In horizontal rock layers, the oldest layer is at the bottom. Each higher layer is younger than the layers below it.
Explanation:
The idealized six-horizon soil profile is not a good representation of all soils because there are big variations, mainly because of the climate factors.
Explanation:
When a soil profile is presented, it is often the one that pretty much everyone knows, the six-horizon profile. This is not a good representation of all soils though, or rather for most of the soils, as the situation in reality is much different. This six-horizon profile is actually idealized, or rather as to how a soil profile should look like.
Lot of the soil types across the world don't have six horizons, or their depths are much different than in the idealized profile. The main reason for this is the climate, as it is the basic factor that later influences all the other ones that influence the formation of soil. We can take the desert soil and polygonal soil as examples:
- The desert soil is very poor in nutrients. The O horizon is either few mm or non-existent. It contains salts.
- The polygonal soil is also very poor in nutrients, with the O horizon also being just few mm. This soil lacks rock base, as well as depth, as it is often only few cm deep.

Answer:
2kg
Explanation:
Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
Answer:
The chemical reaction is: AB + CD ---> AC + BD (ΔH= - )
Explanation:
After the reaction between two reactants, two products are generated.
As the products have less energy than the reactants, this energy is released and ΔH is negative
