In many cases, one type of organism puts selection on another, so they evolve together. For example, flowers and the pollinators. This is called artificial selection Above statement True or False? give explanation
Which of the following situations will lead to natural selection? a. The seeds of two plants land near each other and one grows larger than the other. b. Two types of fish eat the same kind of food, and one is better able to gather food than the other. c. Male lions compete for the right to mate with females, with only one possible winner. d. all of the above
Explain how artificial selection is like natural selection
The domestication or breeding of animals to have as pets, livestock on farms, or for work purposes is a form of artificial selection. Charles Darwin used these practices to support his theory of species change by natural selection. How is artificial selection similar to natural selection? When animals with favorable traits are bred with animals with unfavorable traits, the offspring will have favorable traits, so breeders were changing species by removing certain traits. For artificial selection to work, only the strong survive to reproduce. By breeding animals with specific traits, breeders were able to produce a wide variety of breeds within a short period of time. Artificial selection involves breeding two different species and determining if a hybrid organism can be produced.
Types of Selection Match each situation to the type of selection most likely to occur. NOTE: If you want to change your selection, you'll need to delete the one you already chose. After you delete it, the list of choices will pop back up and you can make a different choice. Rabbits with medium colored fur blend into the background, but very light or very dark fur colors are easier for predators to spot. disruptive selection Drab colored guppies are less likely to be eaten by predators, but brightly colored males are preferred by females. sexual selection Butterflies with small wings can easily find hiding places to escape predators. Butterflies with large wings can fly higher and faster to directional selection stabilizing selection escape predators. A species of rodent is vulnerable to cold weather when small, but able to keep warm when large.
Which of the following best describes natural selection? O It is a guess made by scientists about how life develops, but it has no hard evidence to support it. It is the idea that the strong survive and the weak die off. It is the idea that organisms with genetic traits that improve their ability to reproduce are more likely to pass those traits on to future generations. It is the idea that organisms naturally increase in complexity and intelligence with time.
When discussing natural selection and behaviour, we often say that members of a species have certain behavioural traits because those traits are adaptive, in the sense that they increase inclusive fitness relative to alternative forms of those traits that have existed in the past. Instead of emphasizing the adaptiveness of behavioural traits, some biologists describe natural selection as a process that operates on nervous system traits, increasing the prevalence within a population of particular patterns of neural circuitry and neurobiological mechanisms. As an alternative to emphasizing either the behaviour or the nervous system, some biologists describe natural selection as a process that operates on genes; according to this perspective, certain forms of certain genes (ie., particular alleles) increase in prevalence within a population relative to alternative forms of those genes. Which, if any, of these three perspectives on natural selection and behaviour do you think is the most…
Which statement is accurate about natural selection? It is a biological process that prevents species from adapting to significant changes in their environments. It is a biological process that leads a population to have a widespread expression of an advantageous trait. It is a biological process that allows a population to have a competitive advantage in many environments. It is a biological process that causes certain traits to be expressed less with each subsequent generation.
Consider the roles of different types of selective pressure. Part A: Compare and contrast sexual selection, artificial selection, and natural selection. Part B: Give examples of traits that may be favored in sexual selection, artificial selection, and natural selection. For each, explain if the trait would be favored by one type of selection but selected against by another type of selection. BI 1000 MacBook Air O00 F1 F2 F3 F4 F5 F6 F7 F8 $ % & * 2 3 4 6.
