The graph shows the amount of pesticides and fertilizers detected in a pond ecosystem that had cricket frogs, alligators, and mosquitoes.

a graph with the title amount of chemicals. the y axis title is chemicals and next to it is an arrow pointing upwards. the x axis title is year and the values 1, 2, 3 4. 5 are marked on the x axis. a solid graph line is shown sloping steeply upwards. a broken graph line is also shown with a lesser slope. a key is shown at the bottom right of the graph. next to the straight line is written pesticides and next to the broken line is written fertilizers.

if the population of alligators and mosquitoes remains the same during this period, what is most likely going to happen to the population of cricket frogs over time?

increases as the habitat is increasingly polluted
decreases as the habitat is increasingly polluted
remains the same as prey population remains the same
remains the same as predator population remains the same

At which location in earth’s interior does the top density continue to increase as thickness decreases?

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
