The
latitude of any location on Earth is the angle formed by the two
rays down from the center of Earth to the location and to the
equator. The ray through the location is the initial ray. Use 3960
miles as the radius of the Earth. Suppose City A is due north of
City B. Find the distance between City A (north lattitude 41
degrees 17' N) and City B (latitude 32 degrees 47')
the distance between City A and...
Discuss the different stages of a mid-latitude cyclonic storm
from birth to decay according to the polar front model.
How does the magnitude of the sea level pressure change with
time?
How does the associated frontal structure change with
time?
Why do they tend to die out after they become occluded?
At a given latitude, ocean water in the so-called "mixed layer"
(from the surface to a depth of about 50 m) is at approximately the
same temperature due to the mixing action of waves. Assume that
because of global warming, the temperature of the mixed layer is
everywhere increased by 0.1 ∘C, while the temperature of the deeper
portions of the ocean remains unchanged.Estimate the resulting rise
in sea level. The ocean covers about 70 %of the Earth's
surface.

Cell surface receptors. Diagram the reception, transduction,
& response for hormones that act on cell surface receptors.
What does the G Protein-coupled receptor cladogram say?
What do second messengers do?
Signaling cascades. How does this amplify a signal?
How can different types of cells respond differently to the same
hormone?
Steroid hormones: Diagram the reception, transduction, &
response. Why are the mechanisms different for steroid hormones vs.
protein hormones? Are the signals amplified?
Describe how components of the cytoskeleton, cytoplasm,
cell surface and extracellular matrix interact to form cell
junctions and the roles of distinct junction types in
skin
In which of the following cases is a polar covalent bond
formed?
when the electrons of a bond are shared equally by the two
atoms
when the electrons of a bond are shared unequally by the two
atoms
when an electron is transferred from one atom to another
when a metallic element forms a bond with a non-metallic
element
Storms
What is the difference between mid-latitude and tropics
cyclones? Why do cyclones rotate counter-clock wise in the northern
hemisphere but clock-wise in the southern hemisphere as shown in
the chart below? Unlike hurricanes, why is it difficult to predict
the time when a tornado occurs? Explain why the Midwest U.S is
considered as a ‘tornado alley?’ Why are the months of May and June
the peaks times for tornado occurrence? must be 350 words long
