The appearance or quality of light reflected from the surface of a mineral is known as luster.
In mineralogy, luster refers to how a mineral surface appears in terms of its capacity to reflect light. The degree of transparency, diaphaneity, and structure of a mineral all affect its luster.
A mineral's ability to reflect light is referred to as luster. The first step in identifying a mineral is to measure it. Always examine a brand-new surface for luster; you might need to remove a tiny amount of material to reveal a clean sample. Metallic luster, which is extremely reflective and opaque, to dull luster (non-reflective and opaque.)
Mineralogists use the physical characteristic of luster to identify minerals. A mineral's luster defines how its exterior reflects light and how its inside may bend or refract light. Some minerals have a metallic sheen, while others don't.
A mineral reflects light by having a luster. The two main categories of luster are described by the labels metallic and nonmetallic. The most popular words for luster are shown in Table 7, along with an illustration of a comparable mineral. Some minerals are described as "earthy," "chalky," or "dull" because they lack luster.

Answer:
Nitrogen
Explanation:
The Percentage of given gases in atmosphere:
Oxygen = O₂ = 20.95 %
Nitrogen = N₂ = 78.08%
Argon = Ar = 0.93%
Ozone = O₃ = 0.000004%
Nitrogen is most abundant gas in atmosphere while oxygen is second most abundant gas. The nitrogen and oxygen are present in diatomic form such as O₂ and N₂.
Water vapors are also present but the percentage vary according to location. In hot humid areas the percentage of water is 0- 4% and it is third abundant gas.
The percentage of other gases in atmosphere are given below:
CO₂ = 0.0360%
Ne = 0.0018%
He = 0.0005%
CH₄ = 0.00017 %
N₂O = 0.0003%
H₂ = 0.00005%
Answer:
Paramecium is a genus of eukaryotic, unicellular ciliates, commonly studied as a representative of the ciliate group. Paramecia are widespread in freshwater, brackish, and marine environments and are often very abundant in stagnant basins and ponds
Answer: Efficient functioning.
Explanation:
Cells require a lot of substances to both come into and leave the cell in order for the cell to accomplish it's functions. These substances can be anything from carbohydrates to water and they come into the cell through diffusion and osmosis.
The thing about diffusion however, is that it happens faster over shorter distances than longer distances. This is why cells are so small. They evolved to be that size to ensure that diffusion of these substances takes place relatively quickly so that they can use these substances to carry out their functions at a faster rate.
1. Photosynthesis is important because oxygen is released as a byproduct. We need that oxygen to survive.

2. Photosynthesis helps get rid of the carbon dioxide in the air. Carbon dioxide, as you may probably know, is necessary for this process to occur</span>
