What causes matter to be in a particular state (phase)?

Answers

Answer:

In the physical sciences, a phase is a region of space (a thermodynamic system), throughout which all physical properties of a material are essentially uniform. Examples of physical properties include density, index of refraction, magnetization and chemical composition. A simple description is that a phase is a region of material that is chemically uniform, physically distinct, and (often) mechanically separable. In a system consisting of ice and water in a glass jar, the ice cubes are one phase, the water is a second phase, and the humid air is a third phase over the ice and water. The glass of the jar is another separate phase. (See state of matter § Glass)

those organisms that are best adapted to the environment will survive to produce more offspring
D all organisms are made up of cells

Answers

Answer:

C. those organisms that are best adapted to the environment will survive to produce more offspring

Explanation:

Natural selection is a key concept in the formulation of the theory proposed by Darwin in 1859. Natural selection is defined as the main force that drives the prevalence and the increase of advantageous phenotypic traits. Selection natural acts by differential survival and reproduction of individual organisms that have better adapted to the environmental conditions in which these organisms live. These organisms with a greater adaptive fitness have more chances to survive and reproduce, thereby transmitting (and perpetuating) their genes to the following generations.
