Answer: C). A biozone can help trace the path of evolution over time.
Biozone is a stratigraphic unit which contains fossils in layers of strata existed in a particular geologic period. It is named as biozone because it depicts the number of biological taxa existed in particular strata. Therefore, the variation in features within taxonomic groups in biozones can give indication of evolution with respect to time.
Graph B, because the percentages between G and C are equal. Chargaff’s rule states that G = C and T = A. The graph correctly demonstrates this.
Answer:
<u>D) melting and soliditation</u>
Explanation:
Granite is a type of grainy (medium-coarse) igneous rock. These are formed from quartz, alkali feldspar and trace minerals along with plagioclase. Rocks like quartz, form a crystal from magma or as a precipitate near hydrothermal vents.
A type of intrusive igneous rock, granite is formed from its constituents when it molten rock cooled. Larger mineral crystals are associated with slower cooling over time.
Answer/Explanation:
Density-dependent limiting factors are non living and biotic factors that affect the size and growth of a population based on the population density, while density-independent limiting factors are those factors that do not depend on the density of a population before they can have an effect on the growth and size of the population.
Examples of density-dependent limiting factors are predation, disease, Parasitism, competition. These rely on the density of a population in order to affect the growth and size of a population.
On the other hand, examples of density-independent limiting factors are pollution, flood, temperature.
