46 european green crabs were first discovered in willapa bay in washington state in 1997. scientist studied changes in the size of european green crabs in this area by measuring the widths of the crabs carapaces during a five - year period. the graph presents the scientists data. which of the following statements about european green crabs in willapa bay is best supported by the data? a. the range of european green crab carapace size was greater in 2001 than in any other year of the study period. b. the european green crab population was smaller in 1998 than in any other year of the study period. c. changes in a european green crab habitat affected the size of the european green crab carapace. d. the european green crab carapace size increased steadily throughout the study period. 47 why did the scientists most likely sample european green crabs from multiple locations? a. to avoid sampling a similar species of crab b. to avoid sampling a different species of crab c. to increase the amount of the data collected d. to increase the range of water temperatures measured 48 the following is a diagram of a rocket travelling in a remote region of space where no outside forces act on the rocket. the engine of the rocket applies a force to the rocket. how would the speed of the rocket change over time? a. the speed of the rocket will continue to increase until the engine runs out of fuel, and then the rocket will slow down. b. the speed of the rocket will continue to increase until the engine runs out of fuel, and then the rocket will maintain a constant speed. c. the rocket will attain a maximum speed long before the engine runs out of fuel, and after it runs out of fuel, it will slow down. d. the rocket will attain a maximum speed long before the engine runs out of fuel, and after it runs out of fuel, it will maintain a constant speed.

Answer

Answer:

  1. A
  2. C
  3. A

Explanation:

Step1: Analyze 46

From the graph, in 2001 the spread of carapace - width values (range) is greater than other years.

Step2: Analyze 47

Sampling from multiple locations increases data amount. Other options are not main reasons.

Step3: Analyze 48

According to Newton's second - law, as long as there is a force (engine force) acting on the rocket, its speed will increase until the fuel runs out, then it will slow down due to lack of force.
