Information in TEXT A student investigated the viscosity of liquid hydrocarbons
A viscous liquid is a liquid that flows slowly
The student used this method
Measure 50 cm of the liquid hydrocarbon
Pour the liquid hydrocarbon into the funnel, as shown in Figure 1
Figure 1
Funnel
-Liquid hydrocarbon
A
Time how long it takes for all of the liquid hydrocarbon to run out of the funnel.
Repeat the experiment for other liquid hydrocarbons.
What is the indenendent variable?

Use this information to determine the number of calends electrons in the atoms. which of the following correctly compares the stability of the two atoms? a) both are unreactive b) both are highly reactive c) a is unreactive and d is reactive d) a is reactive and d is unreactive

Many bird species build nests in which they raise their offspring. one of these species is known as the magnolia warbler. breeding pairs of magnolia warblers build nests out of pieces of grass and twigs. the female warbler will then lay her eggs in the nest and sit on the eggs for a few weeks until they hatch. after the offspring have hatched, the female will continue to sit on the newborn chicks to keep them warm. both the male and the female bring food for the offspring to eat until the young are mature enough to find food on their own. which of these most likely describes why birds such as the magnolia warbler build nests in which to raise their offspring? a. nest building decreases the amount of energy used by the parent birds to raise their offspring to adulthood. b. nest building increases the probability that the offspring will survive and eventually produce offspring of their own. c. nest building decreases the amount of food that the offspring require the adult birds to provide. d. nest building increases the probability of the offspring being located by airborne predators.
