Answer & Explanation:
An organic molecule is one which contains carbon, although not all compounds that contain carbon are organic molecules. ... Although carbon is present in all organic compounds, other elements such as hydrogen (H), oxygen (O), nitrogen (N), sulfur (S) and phosphorus (P) are also common in these molecules.
Answer:
Grade of metamorphism
Explanation:
Gneiss forms at a higher grade of metamophic slate. Slate forms at low metamorphic conditions just about a few temperature and pressure.
From the prolith materials exposed to metamorphic conditions, transformations begins as metamorphic changes begins to take place. First, a sediment is transformed into slate, from slate to phyllite, from phyllite to schist, schist to gneiss, gneiss to migmatite and migmatite goes back to melt. These transformation of sediments is controlled by the nature of the prolith materials and the prevailing metamorphic conditions.
Answer: Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.
Surface tension is the property of water which allows for some lightweight insects to walk on top of a pond and not fall in. The molecules of water are held together by cohesive forces. The molecules of water present below the surface experience this cohesive force from all the directions, whereas the water molecules present on the surface experience a downward pull, as the force is not balanced. This leads to the concaving of the water surface inside a small tube.
The endoplasmic reticulum, or ER, and Golgi apparatus, prepare molecules, including proteins, hormones and lipids, and package them in vesicles for transport. Rough ER is studded with ribosomes that synthesize proteins, while the smooth ER manufactures lipids.
