Answer:
Option B
Explanation:
Special hyphae known as arbuscules are formed by fungi and these structure are formed in the phylum and roots of the vascular plants.
These perform the function of the absorption of nutrients and water from the soil promotes the growth of the plant.
The fungal hyphae helps in the physical binding of the particles of the soil together and creates stable aggregates that promotes the infiltration of water and improves the retaining capacity of water in the soil.
Answer:
Cleavage
Luster
Streak
Hardness
Explanation:
Cleavage is the ability of a mineral to split apart easily along flat surfaces and it is dependent on the mode of formation and properties of the mineral.
Luster is the way light is reflected from the surface of the mineral. Some minerals allows a greater reflection of light due to their shiny surfaces while some don’t.
Streak is the color of the mineral's powder which are its unique components and also helps in the identification of minerals.
Hardness of a mineral can be measured by the Mohs scale. This is usually measured on a scale of 1-10. The hardest being 10 on the scale.

Answer:
The watershed simply restricts the movement of water toward one side, because the water can not move up but only down or on a flat area.
Explanation:
The watersheds represent physical boundaries that are separating the flow of water to rivers, seas, areas, or to put it simply, they direct the movement of water in different directions. The watersheds are marked by landforms that are at a higher elevation than their surroundings, and the separation of the movement of water occurs at the ridges.
Basically, the water moves downward on each side of the ridge. This means that the water on one side of the ridge belongs to one watershed as its waters go in one direction and area, while the water on the other side of the ridge belongs to another watershed because its waters move in another direction and area.
Theory of Continental Drift
If you take a look at a map of the earth today, you will see the current locations of broken land masses that constitute the earth. However, would you believe if someone told you that these broken land masses were once connected to each other as one huge supercontinent? Well, this claim was made in the 90’s by Alfred Wegener, a German polar researcher, meteorologist and geophysicist who died in 1930.
Wegener’s theory of continental drift states that the existing continents of the earth were once glued together forming a super landmass. Over time, the landmass broke and drifted away and is still drifting to this day. In his proposal, he stated that the super content, which he named Pangaea, meaning ‘’all earth” once existed. The supercontinent was surrounded by water bodies, mainly oceans, and seas.
