What are the different types of selection or system of elimination?
I don't think there's a certain type as such. Selection and Elimination can be structured or random. Random is self-explanatory, structured, is based on the individual/the criterion, i.e. I will pick all the green and red Easter eggs out of a packet, etc.
Who controls natural selection?
In some cases, the direction of evolution is intentionally controlled by humans. We call this artificial selection, or breeding - as in the breeding of cattle. In all other cases, nobody controls the direction of evolution.
Which tends to occur more quickly natural selection or artificial selection?
Artificial selection tends to occur more quickly than natural selection because it involves intentional breeding by humans to promote desired traits in organisms. This focused approach can lead to rapid changes in specific characteristics over a few generations. In contrast, natural selection operates through environmental pressures and can take much longer for significant changes to occur, as it relies on random genetic variations and survival advantages over time.
What is genetic drift increased by?
Lack of a selection factor. In the absence of selection pressure from natural, sexual or artificial sources, the propagation of random genes would increase. Mutation rates may also be tuned to optimise genetic drift (emphasis on may!).
Explain why mutations are random occurrences than planned alteration?
Mutations are random occurrences because they result from changes in the genetic material that are typically spontaneous and not influenced by any specific goal or plan. They can happen due to various factors such as exposure to mutagens or errors during DNA replication. As such, mutations are not a deliberate or controlled process but rather a natural phenomenon that contributes to genetic diversity.

Why is natural selection random?
No. Natural selection is the non-random survival of randomly varying replicators. The random variation part could be thought of as mutation and recombination that the non-randompart, natural selection, works with.

Why is light from a common lamp nonpolarixed?
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.
Why is light from common lamp or from a candle flame nonpolarized?
Natural light sources and artificial sources emit light with orientations of the electric vector that are random in space and time, thus proving to be nonpolarized.
What is random variation?
Random variation refers to the natural variability observed in data that arises due to chance or random factors. It can impact the results of experiments, making it important to account for this variability when drawing conclusions from data. Random variation is often controlled for using statistical methods to ensure that patterns or effects observed are not simply due to chance.
What are the Elements of the theory natural selection?
Replication random variation Non-random survival
What describes genetic drift?
random changes in allele frequency (apex) [Correct]
A study of small group behavior of a selected random group is call a?
controlled experiment
What is a study of small group behavior of a selected random sample called?
controlled experiment
Why is radioactivity unpredictable?
Radioactivity depends on subatomic processes, and those are inherently unpredictable. The "why" is difficult to answer; but it seems that's the way our Universe works. You can calculate probabilities only.
What is natural selectiuon?
Natural selection is the non-random survival of randomly varying replicating organisms.
