Phosphorus cycles between living things and the SOIL
Explanation:
Phosphorus flows in a cycle within rocks, water, soil and sediments, and organisms. The phosphorus cycle is the biogeochemical cycle that represents the action of phosphorus within the lithosphere, hydrosphere, and biosphere. Phosphorus is an essential element for all sorts of life. As phosphate (PO4), it delivers up an essential part of the structural core that holds DNA and RNA mutually.
volcanic activity
Answer: Option D.
<u>Explanation:</u>
Volcanoes are regular along tectonic plate boundaries where oceanic plates sink underneath different plates. As a plate sinks profound into a subduction zone, it warms and starts to soften, shaping magma.
Volcanoes are likewise basic along structural limits where plates pull separated, permitting magma to ascend from the mantle.Volcanoes are generally basic in these geographically dynamic limits. The two sorts of plate boundaries that are well on the way to create volcanic movement are divergent plate boundaries and convergent plate boundaries.
Answer:
True
Explanation:
The Polymerase Chain reaction (PCR) is a technique widely used in molecular biology to identify specific DNA fragments generally in a size range of 100 to 1000 base pairs (bp). PCR sensitivity refers to the potential of the PCR technique to specifically amplify the desired sequence in the sample. PCR is a highly sensitive (and also specific) method with values around 100% if the experimental conditions are proper. However, to reach these values, it is imperative to work in optimal conditions by eliminating contaminant factors in the sample which may alter PCR amplification.
