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.
"Crepuscular" means active at dawn and dusk, so if you wanted to avoid coming across the Gila monster when hiking in Arizona you would want to avoid dawn and dusk.
Answer:
Regular insulin
Explanation:
Regular insulin is a fast insulin. After being applied, its onset of action takes between half an hour and its maximum effect occurs between two to three hours after application. It is usually used to treat type 1 diabetes mellitus, type 2 diabetes mellitus, gestational diabetes, diabetes complications such as diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar coma.
Answer:
B. By taking in inorganic substances
Explanation:
When you think of autotrophs, you may think of plants, and how do plants get nutrition?
By taking in inorganic substances like carbon dioxide or sunlight, then converting it into energy.
