Answer:
When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss. Slate is another common metamorphic rock that forms from shale. Limestone, a sedimentary rock, will change into the metamorphic rock marble if the right conditions are met.
Answer:
Using a hot plate to heat an unknown liquid in a glass flask could be dangerous if protective/safety equipment aren’t worn. The unknown liquid may be a corrosive chemical which could cause burns when it gets in contact with any part of the body. It s therefore advisable to use googles to prevent the chemicals from splashing into the eyes. Safety gloves and long sleeve shirt should be worn to prevent heat and chemical burns. A shoe covering the whole part of the feet should also be worn as accidents such as the falling to the ground of the heated liquid may occur in the laboratory. This will help protect the feet from contact with the unknown liquid. Nose masks should also be put on to prevent inhalation of toxic chemicals into the body.
A sharp, stinging odor would most likely be a defense mechanism for a plant.
Answer: D(nucleoid region)
Explanation:
In the diagram below the irregular shaped, supercoiled region, without a membrane, labelled D, surrounded by the cytoplasm of the cell is the nucleiod region that contains the main DNA in bacterial.
The nucleoid region in the prokaryotic cell contains the main DNA material. The nucleoid which means nucleus-like contains the main genetic material in prokaryotic cell, some satellite DNA are found in plasmid is other parts of the cell. Unlike the nucleus of eukaryotic cells the nucleiod lacks a cell membrane. The nucleiod has an irregular shape, and has a circular chromosome.
Answer:
Vascular tissue includes xylem, phloem, parenchyma, and cambium cells.
