Answer is A. Archaebacteria
Archaebacteria are a type of single-cell organism. They are a group of most primitive prokaryotes which are believed to have evolved immediately after the evolution of the first life. Thermoacidophiles are the archaebacteria which can tolerate high temperature as well as high acidity. They often live in hot sulfur springs where the temperature may be as high as 80°C and pH as low as 2. Examples are Thermoplasma, Thermoproteus.
Rock A = It is a metamorphic rock that experienced tremendous heat and pressure due to massive, moving tectonic plates.
Metamorphic rocks are rocks that have been somewhat squished and transformed by heat and pressure. These rocks often have different layers as the rocks go through pressure and are literally look like rocks that have been piled up and then stuck together. The best indicator of this rock being a metamorphic rock is the wavy elongated stripes. The stripes are created from the different rock elements being pressed together over time.
Rock B = It is a sedimentary rock made primarily from lithification of organic material.
Sedimentary rocks are rocks that have been formed by different substances that come together due to the different weather conditions. The best indicator of this being a sedimentary rock is how the rock came together and looks like a bunch of shells were glued together.
Rock C = It is an igneous rock that was formed above Earth’s surface.
Most igneous rocks have smooth outer layers. These rocks are often made with solidified magma from volcanoes. The best indicator of this being an igneous rock is the indication of it being a solidified piece of magma.
Protists can be either heterotrophs or autotrophs.
They have nuclei.
They can live anywhere.
They can reproduce sexually or asexually.
They are both multicellular and unicellular.
(Where's number 4?)
i think its c b/e icland is situated in the top of a multiple volcanoes and harnesses this natural power to heat the roads and sidewalks in the winter
