ARF is an abrupt reduction in glomerular filtration
rate characterized by an increase of blood urea
nitrogen (BUN) and serum creatinine.
It may result from :
- decrease in effective circulation
- renal cell injury
- arterial or venous obstruction
- obstruction to urine flow.
Commonest cause in children: dehydration
2
If renal function was previously normal ARF occurs if
50% of GFR is lost.

During a medieval siege of a castle, the attacking army uses a
trebuchet to hurl heavy stones at the castle walls. If the trebuchet launches
the stones with a velocity of +30.0 m/s at an angle of 50.0°, how long does it
take the stone to hit the ground? What is the maximum distance that the trebuchet
can be from the castle wall to be in range? How high will the stones go? Show
all your work.

1. An experiment was devised to
investigate the effects on the temperature of a cup of coffee when cream is
added at different time intervals. Hot and cold water were used instead of
coffee and cream. First, a container of water heated to 80°C was allowed to sit
for 15 minutes. Its temperature was measured at regular intervals. Next,
similar temperature measurements were taken for 15 minutes on a new container
of heated water, but this time some cold water was added after the 2-minute
reading. Finally, the procedure was repeated except that for this last test,
the cold water was added after the 12-minute reading. The resulting recorded
temperatures were plotted on the graph shown here. NUMBER2
Based on the information given here,
answer the following questions about the experiment.
·
What question was asked in the experiment?
·
What was the hypothesis, expressed as an if-then statement?
·
What were the independent and dependent variables?
·
What was the control in the experiment?
·
Were there any sources of error in the experiment? If so, what?

Concorde Career College Human Skeletal System and Simple Machine Question
The bones and joints within the human body are complex and very important to movement. They work as coordinated systems, much like machines.
What are two simple machines or devices that remind you of different mechanisms within the human body’s skeletal and articular systems? Mention the part of the human body, what machine or other device it reminds you of, and how the body part and machine or device are similar. You might take a particular joint and relate it to a type of simple machine. The action that a muscle produces when it pulls on a bone, for example, is similar to a simple machine called a lever.
