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.

Please Help! Factors affecting the rate of Photosynthesis.
PtichkaEL [24]

Factors affecting photosynthesis

Three factors can limit the rate of photosynthesis: light intensity, carbon dioxide concentration and temperature.

Light intensity

Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the rate of photosynthesis.

A graph with rate of photosynthesis on the y axis and light intensity on the x axis. The plotted line rises steeply and then levels off to horizontal.

Carbon dioxide concentration

Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.

A graph with rate of photosynthesis on the y axis and light intensity on the x axis. The plotted line rise steeply and then levels off to horizonal. During the steep part light is the limiting factor. During the horizontal part another factor has become limiting.

TemperatureIf it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.

A graph with rate of photosynthesis on the y axis and carbon dioxide concentration on the x axis. The plotted line rise steeply and then levels off to horizonal. During the steep part carobn dioxide is the limiting factor. During the horizontal part another factor has become limiting.

If you plot the rate of photosynthesis against the levels of these three limiting factors, you get graphs like the ones shown above.

In practice, any one of these factors could limit the rate of photosynthesis.

3. Describe the working of the body's nonspecific defenses<br> against disease.
dezoksy [38]
Nonspecific defenses include physical and chemical barriers, the inflammatory response, and interferons. Physical barriers include the intact skin and mucous membranes. These barriers are aided by various antimicrobial chemicals in tissue and fluids.


Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN. Specific defenses include antibody and cell-mediated immunity.
