The sample columns have two missing layers as follows:
- Column 1: Layers 3 and 8 are missing.
- Column 2: Layers 1 and 7 are missing.
- Column 3: Layers 1 and 5 are missing.
<h3>What is geology?
</h3>
Geology is a term to refer to the specialized science that focuses on the study of the composition and internal and external structure of the surface of the planet Earth, and the processes by which it has evolved throughout geological time.
In the image 3 columns are shown showing various layers of the Earth, however, each of it has 2 missing layers. To know which layers were missing from each one, we must analyze them to establish what a column with complete layers would look like and then compare the 3 samples with the model to know which layers are missing.
According to the previous process, it can be inferred that the missing layers in each column are:
- Column 1: Layers 3 and 8 are missing.
- Column 2: Layers 1 and 7 are missing.
- Column 3: Layers 1 and 5 are missing.

When evolving, microorganisms such as harmful bacteria may develop a resistance to antibiotics. This means that the disease the bacteria in question cause will be harder to treat. This is quite bad since bacteria can pass on traits to other bacteria without even multiplying.
The flu virus is also a good example. Generally, the virus itself mutates quite frequently. This means that with each mutation the virus has a potential to gain a genetic trait which may cause more severe flu symptoms or a resistance to drugs/the antibodies our bodies produced to counter-attack the type of flu virus it has previously encountered.

Water in the soil is held tightly by adhesive forces between the water molecules and the mineral content in soil particles - in the microspores.
Explanation:
While water passes through the macrospores of soil by gravity, water passes through the microspores mainly by cohesion between the water molecules and adhesion between the water molecules and soil minerals. The more surface area for the minerals in the soil (due to finer particle sizes) the higher the water retention rate of the soil. This is why soil with more humus (like silt and clay) retains water more than soils like sand.
