Right ventricle
31. Which component of blood is 90 percent water?
PLASMA
Excretory System pg 579-583
32. What is structure A?
KIDNEYS
What is its function?
To filter out waste like urea and to remove excess water
33.
What is urea?
Urea is a chemical that comes from the breakdown of proteins. In which
structure—A, B, C, or D—is it removed from the blood? KidneyA
34.What is the term for the tiny filtering structures that make up structure A?
NEPHRONS
Describe what happens in each of those structures. Blood flows in the kidney into
tiny capillaries that are surrounded by a capsule that is connected to a
tube(nephron). Waste is filtered out from the blood into the nephron

during delivery.
40. Human eggs are usually fertilized in the
fallopian tube
Natural Selection-Pg 172-187
41 What are fossils?
Fossils are preserved remains or traces of an organism that lived in the past.
42
What theory proposes that evolution occurs steadily in tiny changes over
long periods of time?
Theory of evolution
43
If two organisms look very similar during their early stages of
development, this is evidence that the organisms
HAVE A COMMON ANCESTOR
44. The gradual change in a species over time is called
EVOLUTION
45. What are the three things that are necessary for isolation and hence the
formation of a species?
Step 1-One member of the species is cut off from the rest of the
species by things as rivers, volcano, or mountain ranges.
Step 2-The cut off species need to adapt ,genetic changes occur
and hence variation would occur.
Step 3-The variations would them be passed on to the next
generation
