Name the structure that increases the surface area of the small intestine in humans.
lutik1710 [3]

The name of the structure that increases the surface area of the small intestine in humans is Villi.

<h3>What are the functions of the small intestine?</h3>

The small intestine performs a key role in the digestion of undigested food which comes through the stomach. It also absorbs all the essential minerals and nutrients from the food and is used by the body.

Villi or microvilli is the structure that increases the surface area of the small intestine for food absorption and adding digestive secretions.

Therefore, the name of the structure that increases the surface area of the small intestine in humans is Villi.

Rock B reacts with hydrochloric acid. State the name of the rock B
choli [55]

Answer:

The sedimentary rock limestone which contains carbonate mineral Calcite and the metamorphic rocks which contain carbonate mineral Aragonite are the examples of rocks which react strongly with hydrochloric acid.

Explanation:

Rocks are naturally occurring structures formed on the Earth's crust and are composed of aggregate minerals. Classification of rocks: Igneous rocks - formed by cooling of magma on Earth's crust or seabed (basalts, gabbros, granite, etc), sedimentary rocks - formed over time by the accumulation of sediments from the weathering of existing rocks or fragments of minerals and organisms (mudstone, sandstone, shale, limestone, dolostone, siltstone, etc) and metamorphic rocks - transformed rocks formed from the existing rocks that are subjected to large pressures and temperatures (schists, gneiss, marble, etc).

The carbonate minerals like calcite, dolomite, aragonite, etc react with hydrochloric acid and release carbon dioxide gas bubbles. Calcite (calcium carbonate), which is found in igneous, metamorphic, and sedimentary rocks in a varying proportion reacts strongly with hydrochloric acid. So, the sedimentary rock Limestone which mainly contains calcite react strongly with the acid while Dolostone which mainly contains dolomite (calcium magnesium carbonate) reacts less vigorously. Another carbonate mineral aragonite, found in metamorphic rocks also reacts strongly with hydrochloric acid.
