Probably d but definitely not A though..
Answer:
Emulsifier
Explanation:
Emulsifier are the chemical additives which are required to breaking up fats or lipids globules into much smaller emulsion droplets.
An emulsifier consist of one oil-friendly and one water-friendly end. When an emulsifier added with fat or lipid, the emulsifier face towards the oil/water or air/water interface reduces the surface tension to make emulsion more stable.
Emulsification of fat makes the food easy to absorbed by small intestine.
Hence, the correct answer is "Emulsifier ".
Complete question:
Geologists are conducting a study on many layers of different types of rock in the Grand Canyon. These geologists will likely find ancient fossils that reveal the history of life near the Grand Canyon in
- igneous rock layers
-
layers of sedimentary rock
-
layers of volcanic rock.
-
metamorphic rock layers
Answer:
layers of sedimentary rock
Explanation:
Most rocks in the Grand Canyon are sedimentary rocks, formed while <em>sediments of sand and mud got deposited in thick layers and got compacted through the pass of time until becoming a rock</em>. Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition. According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.
As the sedimentary layers were deposited chronologically, they reflect the canyon history by keeping in each layer some of the forms of life that used to inhabit this area in the past. Such is the example of the superficial limestone stratum where many marine animal fossils are found, like clams, fish, and corals.
Answer:
From left to right:
- convergent plate boundary
- divergent plate boundary
- convergent plate boundary
Explanation:
Convergent plate boundaries are the ones where the tectonic plates are moving toward one another. This creates subduction zones, trenches, volcanoes (especially strato volcanoes), mountain ranges, earthquakes. This is also where the crust that subducts gets melted into the mantle. The divergent plate boundaries are the ones where the tectonic plates are moving away from one another. They live a gap between them, and through it the magma manages to penetrate from the mantle, reaches the ocean floor, and continuously creates new crust, pushing the old crust sideways and away from the boundary.
