Answer:
C. produced from magma.
D. formed at Earth’s surface
Explanation:
Earth crust refers to the outermost layer or thin shell which makes up the earth such as sedimentary, metamorphic and igneous rocks.
The Earth crust is typically made up of two (2) main types;
1. Oceanic crust: this crust has a thickness ranging from 5 km to 10 km and comprises of denser rocks such as diabase, gabbro and basalt.
2. Continental crust: this crust has a thickness ranging from 30 km to 60 km and comprises of minerals such as quartz, silicate, feldspar, aluminum and less dense rocks such as granite
An igneous rock has a coarse texture and is dark in color. Also, an igneous rock can be accurately described as being produced from magma and formed at Earth’s surface.
Answer:
C. Succinate is the substrate, and fumarate is the product.
Explanation:
Succinate is the substrate of the enzyme Succinate dehydrogenase, and as a product is obtained fumarate. In this scenario, malonic acid plays the role of a competitive inhibitor because its structure resembles the succinate's, so they compete for the active site of the enzyme. So, A option is wrong because fumarate is not the product. B option is wrong too because malonic acid is an inhibitor, not the substrate. Also, D is incorrect because malonic acid is a COMPETITIVE inhibitor, not a noncompetitive one. Finally, E can´t be true because malonic acid is not product and fumarate is the product, not an inhibitor.
