Help! as soon is possible (OWN YOUR OWN WORDS) I will mark Brainliest!!! A major oil spill happened 20 years ago in the Antarctic Ocean. Since then, scientists have been studying its effects on the food chains in this area, like the ones shown in the figure. What prediction can be made about how the presence of the oil spill continues to affect the animals shown in the web? Compare the effects now with those expected 20 years later and be sure to include specific examples of the impact on the different trophic levels.

Suppose you have monohybrid pea plants in your garden and find that they produce round seed to wrinkled seeds in the ratio of 3: 1. if the allele are designated (r & r) receptively. what is the probable genotypes of the round seeds which produced f 1 ? rr & rr rr only rr & rr rr only rr only

Which part of the cell is affected by the movement of molecules through diffusion, osmosis and active transport?

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
