Help me study for my Geology class. I’m stuck and don’t understand.

9)The Hawaii hotspot produces mafic volcanoes while the Yellowstone hot spot produces felsic volcanoes, what does this mean for the relative explosiveness of these two volcanoes ie which would be more and which would be less explosive?

10) Looking at question 9 what is is about the chemical composition that makes one volcano more explosive? Relate the chemical composition of the volcano to the type of crust involved.

)The area we visited was originally volcanic but the rocks we saw were metamorphic.What future geological event on the east coast of the US likely provided the heatand pressure to metamorphose the rock we saw? (hint- there is a HUGE mountain range that runs up the Eastern US and even over into the UK)

Can you help me understand this Physics question?

Do the experiment use i don’t any number (data) for the table, please do it fast, I  at work so I kind busy. please read the page 13-14 Experiment 3: Ohm’s Law do all the question  fill up the table graph, show calculation

Construct a graph of Current (vertical axis) vs Resistance.

? For each of your sets of data, calculate the ratio of Voltage/Resistance. Compare the values you calculate with the measured values of the current.

? From your graph, what is the mathematical relationship between Current and Resistance?

? Ohm’s Law states that current is given by the ratio of voltage/resistance. Does your data concur with this? 

? What were possible sources of experimental error in this lab? Would you expect each to make your results larger or to make them smaller?

I need an explanation for this Biology question to help me study.

Marine Bio Questions

Life on the Benthos I: Lower Invertebrates

1. Describe how Cnidarians and Ctenophores are similar. How are they different?
2. Sea anemones compete for space and this was covered in lecture. Describe how they ‘wage war’.
3. Symbiotic relationships were discussed in the lecture. Define the term symbiosis. What are the 3 main types of symbiosis? Be sure to include an example for each.

4. Compare and contrast the worms in the Phylum Platyhelminthes and Phylum Nematoda.

28 Why did suction-feeding fish evolve at a much greater rate than biting fish?

Identify the labeled parts of the fish in Figure 2(attached): , , , and . try to identify this endemic California fish.

26Define precocious and altricial in reference to animals and give an example of each.

Why is it important to study the amphibious natural history of invasive amphibious fishes? In answering your question, make sure to tie it back to management of these species.

24What is coprophagy and why do some animals do it?

If you were to breed a goat to have more nipples to produce more milk, what would you expect to happen to its litter sizes? Why?

21Why do male baboons commit infanticide and feticide when joining a new troop?

2nd question:

Rock piles

Open ocean

2nd question:

Why do smaller animals generally need to eat more frequently than larger animals? 

13Why is it important to document the species found in areas that have not been well-documented, along with their natural history?

14What kinds of fossils are you most likely to find in San Diego and why? What kinds of fossils are you least likely to find in San Diego and why?
