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.
C. Genetic variation
Bacteria are very numerous, and random mutation of bacterial DNA generates a wide variety of change, including resistance. It happens through mutation and selection. Not only are they capable of sharing genetic bits of DNA to related and unrealted species they can develop ways to remove the antibiotic before it reaches its intended area via biochemical pumps or enzymes to inactiavte the antibiotic.
Answer:
VEGETATION
Explanation:
It is referred to as an infected mass due to the production of bacteria in one heart valves. This infected mass can be due to bacteria in the bloodstream during any dental work, or any similar process related to bloodstream. This infected mass is called VEGETATION and related to endocarditis which is composed of fibrin and platelets.
The mosaic nature is due to the numerous proteins that
are entrenched in the phospholipids bilayer, fluctuate in shape, size and
patterns in the same way as the stones or tiles of a mosaic.
the flexibility is due to individual phospholipids molecules which can move virtual
to one another and gives the membrane a flexible structure that is constantly
changing shape

Answer
Macromolecules in human body
The macromolecules found in human body are:
1. Carbohydrate,
2. Proteins
3. Lipids, and
4. Nucleic acids.
Elements they common share
All these macromolecules have three elements in common which are:
1. Carbon
2. Hydrogen, and
3. Oxygen.
These elements constitute about 95% of human body.
Difference in Chemical properties
Carbohydrate is composed of glucose monomers, which may have aldehyde functional group or ketone functional group. Protein is composed of monomers called amino acids. Each amino acid has carboxylic functional group, amino group, alkyl or aryl group and hydrogen atom. Lipid is composed of fatty acids and glycerol. While nucleic acid is composed of monomer called nucleotide. Each nucleotide is composed of pentose sugar, phosphate group and nitrogenous group. Due to the presence of different functional groups all these macromolecules have chemical properties different from each one
