The eggs and larvae of marine animals tend to require water with more dissolved oxygen in it than the adults do. If water flows from a freshwater source into a salt water bay, what effect would this have on the population of marine animals? The freshwater would decrease the populations of marine animals because it would deplete the salt water of oxygen. The freshwater would decrease the populations of marine animals by decreasing both salinity and oxygen levels. The freshwater would increase the populations, thereby decreasing the levels of oxygen and marine animals. The freshwater would increase the populations of marine animals because it holds more oxygen than the salt water.

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
