Choose 6 liquids to layer. Hypothesize what you expect their densities to be. What liquids did you use, and rank their density w
Lemur [1.5K]

Answer:

Let's pick six liquids randomly, i.e. honey, corn syrup, whole milk, water, vegetable oil, rubbing alcohol, and put them in a beaker. The higher density liquid will take the bottom position whereas lower density liquids will be on above of high density liquids.

We know that honey has density (g/cm3) of 1.42, dish soap has 1.06, corn syrup has 1.33, milk has 1.03, water has 1.00 (standard), and vegetable oil and 0.92. Therefore, honey will be at the bottom most position (rank #1). Above which would be corn syrup (rank #2), dish soap (rank #3), milk (rank #4), water  (rank #5) and vegetable oil (rank #6).

The results might be surprising for some students who think that water has highest density.

11) In a typical energy pyramid about 10% of the available energy is transferred from one trophic level to the next. Consider an
crimeas [40]

Answer: Option B

Explanation:

In a typical energy pyramid the amount of energy that is being transferred is only 10% rest of the energy is lost in the form of heat.

The energy from the sun is converted in the form of chemical energy which is stored in the producers.

10 per cent of this energy is transferred to the next trophic level and rest of the energy is lost in the form of heat. This goes on, there is only a transfer of 10 % energy from the successive levels.

So, if the producers have 200 Kcal/m2/year energy the the primary consumers will have 10% of this energy which is equivalent to 20 Kcal/m2/year and then the secondary consumers will have 10 % of 20 Kcal/m2/year which is equivalent to 2 Kcal/m2/year.
