Which of the following is not an example of natural selection:?
DONT SAY "DO YOUR WORK" please Which of the following is not an example of natural selection: Bacteria becoming resistant to antibiotics. Muscles gained through a lifetime of heavy labor being passed on to a child Herbicide-resistant plants overgrowing a field of corn. Light-colored mice being less likely to be eaten by predators in a white sand desert. AND In a Nutall precipitation test, which of these species should agglutinate (or clump) most when testing with human serum? Sea star Frog Bird Dog AND Biological evolution can occur to an individual over their lifetime. True False
Which of the following is NOT an example of natural selection?
a. insect populations developing resistance to certain pesticides b.people breeding horses to run faster c.bacteria populations becoming resistant to antibiotics d.male birds of certain species devoloping colorful feathers to attract female mates
Can your hair change color naturally?
What I mean by that is for example . Your hair was blonde before, then it changed to a darker blonde Without any chemicals , or dye , just by itself. Is that possible? If your hair changes color by itself as you grow older? ( Not like white hair.. LOL ) I have black hair but I noticed one strand of hair that was brownish lol So i'm curious.... :) ty
Which of the following would be an example of natural selection?
A is the only example of natural selection (in fact, it is almost the definition of natural selection), because natural selection means a favorable heritable trait (ie, a mutation in a gene) becomes more common in successive generations, and an unfavorable trait becomes less common, thus changing the frequency of the gene in the population. B is just a natural disaster, D is not 'natural selection' because scientists are painting the mice and it's not a trait that can be inherited, and C is also not a heritable trait because producing more acorns doesn't mean the tree will pass on a favorable gene, it just means it produces more progeny because it happened to grow taller and probably gets more sunlight.
Can u naturally change ur eye color?
Your eye color naturally changes color depending on what you wear, not a durastic change but for example mine go from light green(my natural color) to green blue, to hazel. You can also if you want to get color contacts to wear to change the color of your eyes. Hope this helps.
Can you please give me at least 15 examples of a natural and man-made ecosystem?
Natural: 1. Aquatic ecosystem: marine and freshwater - any ocean and any lake for example 2. Coral reef - Great Barrier Reef 3. Desert - Sahara 4. Rainforest - Amazon 5. Savanna - African Grassland - Serigetti 6. Taiga - coniferous forests covering most of inland Alaska, Canada 7. Tundra - arctic and alpine - very cold - not many trees - northern Canada and Russia 8. Chaparral - shrubland type - heathland plant community- state of California 9. Littoral zone (intertidal zone) - along shorelines 10. Subsurface Lithoautotrophic Microbial Ecosystem - found in igneous rocks (pores/cracks - underground) home to bacteria and fungi 11. Brackish/Estuarine - mangrove swamp Man-made: 1. - apple orchards 2. - christmas tree farm 3.- parks or gardens 4. - aquariums, 5. - terrariums, 6. - dams 7. - Agricultural Ecosystem • Artificial or Man-made ecosystem - lands for farming, aquaculture,and animal husbandry 8. - man-made lakes and ponds 9. - urban ecosystem - human settlements - Offices, houses, churches, Shopping malls etc 10. - beach resort - alters or changes the natural ecosystem Littoral zone (intertidal zone)
What is an example of a natural disturbance to an ecosystem?
Natural disturbances are one way an ecosystem can become unbalanced. As the name implies, natural disturbances have natural causes, such as weather, geological forces, or biological changes. Fires and floods are examples of natural disturbances that force change upon an ecosystem. Natural disturbances also be caused by diseases, severe storms, insects, volcanic activity, earthquakes, droughts, and long-term freezing.But natural disturbances are also beneficial in some cases. There are even some ecosystems that have adapted to become dependent on natural disturbances to maintain their balance. For example, longleaf pine forests depend on fire to control undergrowth in the forest. Without a forest fire clearing the way for new seedlings to grow, the tiny new trees are unable to compete with the thick brush and die.
What are some non-biological examples of natural selection?
AI : Artificial intelligenceMachine-learning algorithms, increasingly, act like the neural ganglia of organizations; they do the computational heavy lifting, while humans act as messengers and mediators between them. The jobs machine-learners are designed to do are those that help their organizations out-compete other organizations. And this is what we should expect any innovations that approach strong AI to be designed to do, as well: To help organizations compete.As machine-learning algorithms improve, they will gradually be integrated with one another to form coherent, independent competitive systems that approach more traditional definitions of AI. Doing this will increase the system’s overall efficiency, and thus make it more competitive. Humans will be removed from decision-making roles simply as a side-effect.We have moral scruples, empathy, selfishness, biases, and foresight, all of which can limit the competitive effectiveness of the organizations we work for. The systems that win will be those that eliminate these human weaknesses. (We humans might not consider these things weaknesses, but in evolution, even foresight can be a weakness if it prevents you from advantaging yourself over your competitors.)
