Does natural selection change the individul or the population?
The individual is selected and the population evolves. Keep this straight and you will avoid much confusion in the future.
How does natural selection help to change organisms overtime?
Natural selection varies the death rates of individuals in the current generation. As the next generation is born with different traits derived from parents that were survivors of the current generation, the population changes gradually from generation to generation better able to survive longer against the natural selection pressures. Should selection pressures change in the future (and they very likely will) the direction of changes caused by natural selection will also change (with a corresponding but temporary increase in death rates if the change is large and sudden).
Why does production of Gametes through Meiosis would be more beneficial for survival of future generations of an organism?
I recommend reading about "Survival of Fittest" and "Natural Selection" to answer your question. The answer to this question is VERY big. Well, if you want the simplest answer, diversity and selection of good traits within the population.
What is the formula for natural selection?
There is no single mathematical formula for all of natural selection. Although, if you're interested in mathematical descriptions of natural selection, I can recommend you read a few books on population genetics, such as Principles of Population Genetics, by Hartl and Clark.Natural selection occurs when:- There exists a population of organisms that reproduce with variation.- Variant features are inherited by offspring.- The population produces more offspring than can comfortably subsist within its direct environment.- Variant offspring therefore have to compete with one another for resources and mating opportunities.Simply put: the traits of those variants that are better at producing offspring will have a greater frequency in future generations.

How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
What best describes how a species changes over time?
Natural selection causes those organisms that are better suited to survive and reproduce to pass on their genes to future generations, causing their children to be better suited to their environment as well. Over time, these traits that have been selected by natural selection will result in an overall change in a species.
What are the pressures of natural selection?
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
What is the future perfect of decide?
the future perfect of "decide" is "have decided".
Darwin account for the diversity of species?
Darwin proposed that the diversity of species is mainly a result of natural selection, where individuals with advantageous traits have a higher chance of survival and reproduction, passing on those traits to future generations. Over time, this process leads to the accumulation of diverse adaptations suited to different environments, resulting in the vast array of species we observe today.

What was Darwin's theory of natural selection?
Darwin Theory of natural selection was proposed by Charles Darwin in 1858. Darwin believed all plants and animals had evolved from a few common ancestors by means of natural selection. Plants and animals produce many offspring, but some of the young die before they can become parents. According to Darwin's theory, natural selection determines which members of a species die prematurely and which ones survive and reproduce. All living things must compete for a limited supply of food, water, space, and other necessities. The individual plants and animals whose variations are best adapted to conditions have an advantage in this struggle. These organisms, on average, tend to leave a larger number of offspring than other members of their group. As a result, the proportion of the group sharing the traits of the best-adapted organisms increases from generation to generation. Scientists use the term fitness to refer to the ability of an organism to reproduce. For this reason, natural selection is often called the "survival of the fittest." For natural selection to operate, two biological conditions must be met. First, the individuals of a population must differ in their hereditary characteristics. Human beings, for example, vary in almost every aspect of their appearance, including height, weight, and eye colour. People also differ in less-obvious features, such as brain size, thickness of bones, and amount of fat in the blood. These differences have some genetic basis. The second requirement for natural selection is that some of the inherited differences must affect chances for survival and reproduction. When this occurs, the fittest individuals will pass on more copies of their genes to future generations than will other individuals. Over time, a species accumulates genes that increase its ability to survive and reproduce in its environment. There are several types of natural selection. They include (1) directional selection, (2) stabilizing selection, and (3) sexual selection. Directional selection produces new features that help a species adapt to its environment. This type of selection is what most people think of as natural selection. Stabilizing selection occurs if a species is already well adapted to its environment. In such cases, the individuals with average characteristics leave the most offspring, and individuals that differ most from the average leave fewest. Unlike directional selection, stabilizing selection eliminates extreme characteristics, reducing the amount of variation in a population. Stabilizing selection may actually be the most common type of natural selection. Sexual selection occurs primarily among animals. Adults of many species prefer mates who display certain behaviors or have certain external features. Sexual selection explains, for example, why males of many bird species have more colorful feathers than the females.
What is the relationship between natural selection and adaptation?
Adaptation is a future generation, and a natural selection is when the Natural Resources select the generation continued. Natural selection is the evolutionary driver of adaptive change. All organisms born are variations and the variation that survives and reproduces better than its conspecifics will have more progeny with the selfsame adaptation that helped the organism to survive and reproduce. Thus, through mutation leading to variation and mutations leading to improvements on that variation natural selection chooses and shapes the organism to be well adapted to its immediate environment.
How does natural selection produce adaptaions in a species?
Variant traits that increase the number of offspring become common in a population, causing the overal morphology and behaviour of the population to continuously shift to give the best reproductive chances for any given environment.

What is the future tense of decide?
will decide or going to decide or decidingor will have decided.Examples:I will decide about the party tomorrow.I am going to decide about the party tomorrow.I am deciding about the party tomorrow.I will have decided about tomorrow's party by tonight.
What species can become extinct in the future?
Theoretically, any. Species can become extinct due to lack of reproduction, natural disasters (meteors, ice ages, etc.), or sometimes because of slaughter.
