PLTW PBS EOC STUDY GUIDE TEST WITH SOLUTIONS #17
Plasma - correct answer liquid portion of blood, the largest component, contains water,
salt, antibodies, and protein
Erythrocytes (rbcs) - correct answer 45% of blood, contains hemoglobin which gives
blood its red color
Leukocytes (wbcs) - correct answer cells of the immune system, an excess of wbcs can
lead to diseases like cancer
Platelets - correct answer perform clots to repair damage, low platelet levels can be a
side effect of medication or pregnancy
How does blood flow through the heart? - correct answer enters through 2 large veins,
emptying blood into the right atrium. Blood flows to the right ventricle.
How does blood leave the heart and become oxygenated? - correct answer leaves
heart through the pulmonic valve, into the pulmonary artery and to the lungs. Blood
leaves the heart through the aortic valve, into the aorta, and to the body.
Antigens - correct answer a structure on the surface of the cell that allows it to be
recognized by the immune system.
What antibodies does a blood clot with? - correct answer a, not b.
What antibodies does b blood clot with? - correct answer b, not a.
What antibodies does ab blood clot with? - correct answer both.
What antibodies does o blood clot with? - correct answer none.
Nucleotides - correct answer dna's makeup.
What does cytosine pair with? - correct answer guanine.
What does thymine pair with? - correct answer adenine.
Deoxyribose - correct answer sugar found in dna.
Phosphate - correct answer backbone of dna, (-) charged.
What is pyrimidine and what does it contain? - correct answer 1 ring, thymine and
cytosine.
What is purine and what does it contain? - correct answer 2 rings, adenine and guanine.
, Genome - correct answer all of the dna in one cell of an organism.
Organelles - correct answer tiny structures inside of a cell that produce energy,
packaging proteins, housing dna, and more.
Eukaryotic cells - correct answer make up animals, plants, fungi, and protists (have
organelles).
Prokaryotic cells - correct answer don't have any membrane-bound organelles, only
include bacteria. Bacteria doesn't have a nucleus, dna is held in a region called a
nucleoid.
Chromosomes - correct answer chromosomes are long, thin strings of genetic material
made of dna and proteins.
Histones - correct answer proteins that dna wraps around.
Pmr - correct answer a process that allows scientists to create millions of copies of dna.
Restriction enzymes - correct answer enzymes that can cut dna in specific locations
called recognition sites.
Rflps - correct answer fragments of dna.
Gel electrophoresis - correct answer separates dna by size and electrical charge by
moving dna through a gel that has an electrical current.
What is the charge of dna? - correct answer dna is negative so it is attracted to positive
charges.
Algor mortis - correct answer the process that matches the temperature of your body to
the surroundings after death.
Rigor mortis - correct answer when muscles contract or stiffen after death.
What happens 2-4 hours after death? - correct answer the corneas become milky.
What happens 1-145 hours after death? - correct answer insect activity.
Livor mortis - correct answer when blood pools where gravity is after death. Aka lividity.
When does decomposition start? - correct answer 36-48 hours.
What are the 4 chambers of the heart? - correct answer left atrium, right atrium, left
ventricle, and right ventricle.
