Selection occurs when there is variation in a population, that variation is heritable, and individuals with certain traits have a higher chance of survival and reproduction. This process allows advantageous traits to become more common in a population over generations.
High temperature, high pressure, and the presence of hydrogen isotopes like deuterium and tritium are necessary conditions for the continuous fusion of hydrogen to occur in a controlled manner.
In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.
For natural selection to occur, there must be variation in traits within a population, as these variations can affect an organism's ability to survive and reproduce. Additionally, the traits must be heritable, meaning they can be passed down to the next generation. There must also be differential survival and reproduction, where individuals with advantageous traits are more likely to survive and reproduce than those without. Lastly, the environment must exert pressure that favors certain traits over others.
the process must take place underground~ apex
In order to progress from the test execution phase, the following conditions need to be satisfied: all test cases planned for execution must be executed, defects must be logged and tracked, test progress must be monitored and reported, and exit criteria must be met to decide whether to move to the next phase of testing.

Without variation there is nothing to select from.
There must be genetic variation, the variation must be heritable, and there must be differential reproduction (due to competition).
mating must happen randomly
1. No net mutations occur; that is, the alleles remain the same 2. Individuals neither enter nor leave the population 3. The population is large (ideally, infinitely large) 4. Individuals mate randomly 5. Selection does not occur
For a spontaneous process to occur, the conditions must involve an increase in entropy and a decrease in free energy.
Biochemical reactions in the body must occur in a specific order and under controlled conditions in order to maintain the body's functions. Enzymes play a critical role in facilitating these reactions by speeding up their rate without being consumed in the process. Any disruption in the sequence of biochemical reactions or the conditions they occur in can lead to dysfunction and potential health issues.
natural selection or genetic drift

In order for the theory of evolution to hold true within a population, there must be genetic variation among individuals, a mechanism for inheritance of traits from parents to offspring, and differential survival and reproduction based on these inherited traits. These conditions allow for natural selection to occur, driving the process of evolution within a population over time.
For evolution to occur, there must be genetic variation within a population, inheritability of these genetic traits from one generation to the next, differential survival and reproduction based on these traits (natural selection), and long periods of time for changes to accumulate across generations.
