a crystal is any solid that has an organized structure. ... minerals are inorganic, naturally occuring substances that have crystalline structures. so it is a prerequisite to be a crystal in order to be a mineral. all minerals, therefore, form crystals.

Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer.
Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer. This is known as the 10% rule.
The 10% rule states that energy is lost as heat during the process of respiration and metabolic activities, and only a fraction of the remaining energy is converted into biomass that is available as food for the next trophic level.
For example, if a primary producer (such as a plant) has 1,000 units of energy, only 100 units are passed on to the primary consumer (herbivore), and only 10 units are transferred to the secondary consumer (carnivore) in the next trophic level.
Answer:
An Organism
Explanation:
In biology, scientists defined the characteristics which distinguished between a living thing that has life and a non-living thing which do not have the life.
The thing or entity that shows the characteristics of life like made of the cell, reproduce, genetic material and many others are known as an organism. Thus the biology is the field of study that studies the different types of organisms like bacteria, protists, animals and plants or living things present on this Earth.
Thus, an organism is the correct answer.
Answer:
0.4250 mol MgO
General Formulas and Concepts:
Chemistry - Atomic Structure
Explanation:
Step 1: Define
17.13 g MgO
Step 2: Identify Conversions
Molar Mass of Mg - 24.31 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of MgO - 24.31 + 16.00 = 40.31 g/mol
Step 3: Convert
= 0.424957 mol MgO
Step 4: Check
We are given 4 sig figs. Follow sig fig rules and round.
0.424957 mol MgO ≈ 0.4250 mol MgO
