A researcher finds that males in two populations of bowerbirds make different types of structures to attract female birds. The males of population 1 build hut-shaped structures and decorate them with colorful objects. The males of population 2 loosely interweave sticks around a central pole and decorate it with dull-colored objects. Female bowerbirds prefer structures made by males of their own population.

Answers

Answer:

Canada Geese migrate because when winter gets harsh the lakes, ponds, and streams all freeze over so then the Canadian Geese can't eat, so they migrate to somewhere where there is open water. ... From their original home in the North the Canadian Geese fly all the way down to the south.

Explanation:

Answer:

Canadian geese eat grass, during the winter in Canada the snow either covers all pf the available grass, or it dies. So they travel to warmer, southern regions where their grass is still abundant.

Anna wanted to see what battery lasted the longest. She put each battery into a clock and recorded the time that the clock stopped. She used Duracell, Energizer, Kroger brand, and EverReady. Independent Variable (IV): _Type of clock_____________________________________________ __________________________________________ Dependent Variable (DV): ______________________________________________ Control: _____________________________________________________________ Constants:____________________

Answers

Answer:

Independent variable: Type of battery

Dependent variable: Time the clock stopped

Control: None for this experiment

Constants: Same type of clock

Explanation:

Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.

Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY

Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.

Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.

Answer:

Independent variable: Type of battery

Dependent variable: Time the clock stopped

Control: None for this experiment

Constants: Same type of clock

Each year, the United States' federal costs exceed the anticipated national budget. In fact the last time that the United States government was able to end a fiscal year without accruing more debt was in 1960. This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades. The table shown below lists the recorded U.S. national debt amounts, written in standard form, for each decade, from 1960 to the year 2010.


Year U.S. national debt (in U.S. dollars)

1960 $286,330,760,848.37

1970 $370,918,706,949.93

1980 $907,701,000,000.00

1990 $3,233,313,451,777.25

2000 $5,674,178,209,886.86

2010 $13,561,623,030,891.79

For each decade, convert the U.S. national debt amount to a number in scientific notation, rounded to the nearest hundred millions dollars. Enter in numerical answers only.
