Question

A population is any group of individuals of the same species that are theoretically able to interbreed with one another and share some defined area For example, a classroom filled with you and your felow students epresents a population of humans. All of the people living in your city or town aso represent a population of humans, as do all of the humans living in your country Just as you have many diferences in traits from the other humans in your classroom population, any population o organisms will have some variety of traits. Sometimes, these dtfferences in traits are so subtle that they might not even be nobiced at first. Other times, the differences might be internal or blochemical in some way Examine this picture, showing a population of goldfish. Which of the following traits appear to be variable traits in this population? Check al that apply Presence or absence of spots Number of spots Aset of gils Which of the following is not a factor that contributes to variation in a population? O Mutation O Sexual reproduction Evolution Natural selection s a process that occurs because every environm contains challenges organs s ive within t. As a result of varlation in the population, some individuals are better suited to deal with these challenges than others. me i diduals with the beneficial trait are more likely to roduce, which. ?? me, mekes that trait more common in the population Traits that harm an individuas ability to survive become less common, as those individuals often die without reproducing. Thus, because of the natural effects of the environment, some ndividuals are selected to reproduce, and some are not. This graph represents the result of one pattern of natural selection. The horizontal axis represents the range of values of a certain trait, and the red arrows above the graph indicate which values are selected against in the environment. The vertical axis and the yellow curves on the graph, represent how many ndividuals in the population have that trait. This specific graph IC disruptive Range of values for the trait Which of the following scenarios is an example of the type of natural selection in the graph? (Note: None of the scenarios actually involve butterflies, so consider the butterflies in the graph as a metaphoricall representation of the trait being discussed.) O In a population of monkkeys, there is variation in the length of the tall. The trait ranges from short tails to long tails. The monkeys use their tails to help support themselves while in the branches of trees. Monkkeys with short tails cannot get as good a grip on a tree branch and thus suffer from deadly fals more often. However monkeys with long talls are more easily caught by predators O In a population of fishes, there is variation in the maximum size of the adut fishes. These fishes are popular for recreational fishing and eating, but there are laws that allow anglers to keep only the largest fishes. O In a population of small shrub plants, there is variation in the sizes of seeds produced. The seeds range from small and thin to large and thick. The small seeds are small enough that they are able to be spread by the wind. The large seeds are large enough that many animals try to eat them and end up spreading them far from the parent plant in their feces. The middle sizes of seeds are too heavy to blow on the wind and too small to be eaten by animals, so they end up falling below the parent plant, where there 5ite sulight, making it difficult for them to survive

Explanation / Answer

Ans- Presence or absence of spots
Explanation:
From the above picture, it has shown that not all individuals of goldfish have the same gold color. They have variation in color from gold to olive green or even creamy white by presence or absence of spots on their scales.
Ans-Evolution
Explanation:
Genetic variation in a population is caused by mutation, sexual reproduction, fertilization, and recombination between homologous chromosomes.
