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.
An example of a false negative is taking an HIV test and having the test come back negative to say the patient is clean, but in reality they have HIV. Another example of a false negative is a woman taking a pregnancy test saying "not pregnant" (i.e. test is negative), but she actually is pregnant. Between those two examples, it is better to have a false negative pregnancy test because it is non life threatening.
A false positive example would be getting bad news you have cancer, when you actually don't have cancer. Another false positive example is a test saying you have a cold virus, when in actuality you don't. The first example mentioned would have the patient likely go through intense chemo treatments which would greatly affect their livelihood. The second example is a more harmless false positive as it would involve at most a flu shot if anything.
Answer: Growing is capable to a certain living organism. Growth means getting larger in size, and for multi-cellular organisms this is done by making more cells. Plants have special tissues called meristems where growth occurs. Single celled organisms increase their numbers by dividing and making more cells like themselves.

<h2>Question</h2>
please define these words clearly: dependent variable, quantitative data and qualitative data
<h2>Answer</h2>
- Dependent Variable - a variable whose value depends on another variable
2. Qualitative data - Qualitative data is the descriptive and conceptual findings collected through questionnaires, interviews, or observation
3. Quantitative data is data expressing a certain quantity, amount or range.

Answer:
<em>Hey there!</em>
3) Well injection is usually done through the vein because they need the substance to go into the blood.
4) Some people believe that the heart is on the left side because its the left ventricle and atrium responsible and when people hear left they think the heart is on the left.
5) People living in high altitudes don't get as much oxygen so their bodies evolved into carrying ,more RBC so more oxygen is carried into their bodies.
<em>Hope this helps :)</em>
