<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>
Answer:
Rural lands include, but are not limited to, those generally developed to lower residential densities, agricultural activities, resource extraction, timber harvesting, resource conservation, public or private recreation, or open space.
Explanation:
Answer: A
The cells would lose water and shrink. In a hypertonic solution, the
concentration of solute is higher than water in a cell. With this, there is a
net movement of water from inside to outside initiating water to lose from the
cytoplasm and vacuole causing the cell to shrink due to osmosis and achieve
equilibrium.
This process is applied in food preservation where microbial cells will
be dehydrated in a hypertonic environment, making them malfunction and preventing
them to cause food spoilage.
Answer:
a) Kingdom, phylum, class, order, family, genus, species.
Explanation:
Kingdom is the broadest taxonomic category after domain as proposed by Linnaeus. The Linnaean hierarchy of taxon identifies species as the most specific taxon that include only those organisms that can interbreed to produce the fertile progeny.
Several species with some common features are placed in same genus while related genera are placed in same family. Likewise, related families are placed in same order and the related orders are placed in same phylum.
Hence, kingdom is the least specific or broadest taxon that includes all the related phyla while species is the most specific taxon that include only the organisms that can interbreed.
