One way to understand how early environment influences behaviors in similar species is through the "cross-fostering" experimenta
l technique. Suppose that the curly-whiskered mud rat differs from the bald mud rat in several ways, including being much more aggressive. How would you set up a cross-fostering experiment to determine if environment plays a role in the curly-whiskered mud rat's aggression? A) You would cross curly-whiskered mud rats and bald mud rats and hand-rear the offspring to see if any grew up to be aggressive.B) You would place newborn curly-whiskered mud rats with bald mud rat parents and place newborn bald mud rats with curly-whiskered mud rat parents. Finally, let some mud rats of both species be raised by their own species. Then you would compare the outcomes.C) You would remove the offspring of curly-whiskered mud rats and bald mud rats from their parents, raise them in the same environment but without parents, and then compare the outcomes.D) You would replace normal newborn mud rats with deformed newborn mud rats to see if it triggered an altruistic response.
.B) You would place newborn curly-whiskered mud rats with bald mud rat parents and place newborn bald mud rats with curly-whiskered mud rat parents. Finally, let some mud rats of both species be raised by their own species. Then you would compare the outcomes.
Adult moths survive predation by avoiding predators in the day, and at night. They also are able to camouflage into the trees depending on the color of their skin.
Answer:Some different ways that an offspring born from one parent can differ from an offspring born from two parents is that the offspring that has only one parent has the exact same traits that its parent has.
the basic building block of a protein is called an amino acid. There are 20 amino acids in the proteins you eat and in the proteins within your body, and they link together to form large protein molecules.
