Answer the following question given this paragraph: Two species may often interact with each other and have a close relationship. Examples include flowers and the animals that pollinate them. When one of the two species evolves new traits, the other species may evolve matching traits. This is called coevolution . You can see an example of this in Figure below . The very long beak of this hummingbird co-evolved with the tubular flowers it pollinates. Only this species of hummingbird can reach nectar deep in the flowers. Q: What is it called when two species evolve matching traits? Choices: - Allopatric speciation - interconnection - spontaneous mutation - coevolution A:
coevolution

(Answer)
cytosol

Answer the following question given this paragraph: All oxygen atoms have eight protons, and most have eight neutrons as well. What is the mass number of an oxygen isotope that has nine neutrons? What is the name of this isotope?. Q: What is mass number? Choices: - to total number of electrons and neutrons in a nucleus - to total number of protons and electrons in a nucleus - the total number of protons and chondrichthyes in a nucleus - the total number of protons and neutrons in a nucleus A:
(A).
the total number of protons and neutrons in a nucleus
Ques:Answer the following question given this paragraph: Radioisotopes are widely used in medical diagnosis. These isotopes need to have short half-lives so that they can be administered in very low doses, thus minimizing damage to cells. Q: What type of isotopes have short half-lives and are given in very low doses? Choices: - stable isotopes - gasses - radionuclides - radioisotopes A:

Ans:radioisotopes
Answer the following question given this paragraph: For photosynthesis, stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen. Stomata are flanked by guard cells that swell or shrink by taking in or losing water through osmosis. When they do, they open or close the stomata. Q: Stomata must control the transpiration of water vapor and the exchange of carbon dioxide and oxygen that take place during what process? Choices: - glycolysis - spermatogenesis - fertilization - photosynthesis A:
photosynthesis
