helpppA swamp is a wetland habitat that contains areas that are temporarily or permanently flooded. The Okefenokee Swamp is located in southern Georgia. The swamp contains organisms that are adapted to these special environment. Wading birds are commonly seen in a swamp habitat. Elaborate on a reason why wading birds live successfully in the swamp.
A) They can walk instead of flying to get from place to place.
B) Their long legs allow them to wade in the waters without getting wet.
C) Their long legs allow them to wade in the shallow waters to hunt for prey.
D) Standing on their long legs allows them to remain still in the waters and

Wading birds live successfully in the swamp because : B) Their long legs allow them to wade in the waters without getting wet.

Explanation:

Wading birds are common habitat in swamp and muddy areas.

Some wadding birds are crane, egret, heron, sandpipers and ibis

Some characteristics of wading birds are:

Long legs of wadding birds allow them to walk easily in wetland without getting their feathers wet.

They live in water or near water, so their food are mainly aquatic insects, small amphibians and fishes.

Wading birds are also called shorebirds.

1. the question asks the most appropriate, which seems to rule out "all of the above." your choice appears to be the correct one.

2. the protocol described is good for identifying correlation, but not cause and effect. for cause/effect, you need to devise a protocol that will assign the treatment (or not) to groups that have essentially the same "demographics" with respect to all the other variables. your choice regarding control group seems appropriate. random assignment of treatment (choice d) may be appropriate also. (i think you can argue that b and d are just different descriptions of the same method.)

3. d will randomize the birds, but may not guarantee there are 10 in each group. e will do both, so seems the better choice.

comment on question 2

based on the problem statement, it seems clear that confident, attentive drivers are more likely to use daytime running lights. so, the protocol might need to be devised in such a way that the lights would be turned on or off without the driver's knowledge. (an attentive driver will figure it out.) assigning a confident, attentive driver to a group required to drive without running lights might mess with his/her confidence and attentiveness. you don't want your experiment to do that. (nor do you want the experiment to subject a driver to greater risk of accident as a consequence of driving without running lights.) experiments involving human safety are always problematic.

idk what the question is about
