Practice Questions: Sexual Development, The Male or the
Female Reproductive System, The Menstrual Cycle
What is the menstrual cycle?
When an egg develops inside the ovary and is released into
the fallopian tube, to the uterus. When its not fertilized, the
uterine wall fall apart and sheds. Then the cycle begins again.
How and where does sperm develop?
Sperm develops in the seminal vesicle through the process of
meiosis.
How does a male’s penis become erect?
Increased blood flow.
What are the four stages of the menstrual cycle? Explain
them.
Menstruation, -when the uterine wall sheds
Follicular Phase – When hormones are released causing the
follicle to develop inside the ovary
Ovulation – Hypothalumus releases a lot of hormone to the
pituitary gland, the ovary ruptures and a mature egg (follicle)
is released.
Luteal Phase – The follicle disintegrates and the female
reproductive system prepares for menstruation/fertilization—
the uterine lining grows.
The Endocrine System:
What are some conditions that affect the endocrine system?
Addison’s Disease, Osteoperosis, Hashimoto’s, Diabetes,
Hyperthyroidism,
Be able to explain one and how it affects the endocrine
system.
What is the function of the thyroid?
It is located in the throat. It helps increases your metabolism ,
body temperature, and regulates growth and development.
Respiratory System
How does the human respiration system work?
It is so amazing   The diaphragm contracts and you
inhale.
Ph , L , T  Moves to you Bronchi to bronchiole , to your
Alveoli. Then it moves to your blood stream. Then you exhale
CO2. Everything goes in the opp direction.
What effect does smoking have on your lungs?
It can cause respiratory diseases such as, emphysema, chronic
bronchitis and lung cancer. Emphysema causes the loss of
elasticity in your lungs – this makes breathing really hard.
Chronic bronchitis is a persistent lung infection in the lining of
the respiratory tract. Causes coughing, swelling, and pain.
How does blood move through the body?
From the left atrium the blood moves to the left ventricle.
From there it moves out the pulmonary artery to the lungs to
pick up oxygen. It moves back to the heart through the
pulmonary vein and enters the right atrium and right ventricle
to leave through the aorta.
Practice Questions Effect of Global Warming, Effect on
Ecosystems
How does killing dolphins affect a marine ecosystem?
Theres an excess amount of smaller fish – the balance is
ruined. A dolphin is at a higher trophic level. This creates
competition for resources at the lower trophic levels.
Is it safe to eat dolphins, explain why or why not?
No, because of mercury. Dolphins are in the water and
concentrations of mercury condense higher up on the food
chain. This is because mercury deposits itself into fat which is
transferred from trophic level to trophic level.
Explain the reason why greenhouse gasses affect the
atmosphere?
Greenhouse gasses are trapping heat within the
atmosphere. This causes the earths temperature to rise. Ice
melts, habitats are destroyed, ocean levels rise – major
flooding. Hotter oceans can cause stronger storms – thus
major problems for humans and most organisms.
Classwork – 5/26
1. Use the information you learned about carbon-based
molecules to explain a human’s need to participate in the
nutrient cycles.
a. We have to move so therefor we need energy and
we get energy through consumption for Glucose
C6H1206 – we create CO2 as a waste product. Even
if we stopped using fossil fuels we would still be part
of the carbon cycle.
2. In the carbon cycle, through what process does carbon
move from an abiotic resource into organic matter?
a. Photosynthesis, C02 – glucose C6H1206
i. Organic is any molecule with carbon, hydrogen,
and oxygen
3. How does carbon cycle through our immediate
ecosystem? (The South End) Be Specific)
a. Plants take it in Peter’s Park through the process of
photosynthesis. Carbon moves from the atmosphere
as CO2 and moves into the biosphere and takes the
form of glucose C6H1206.
b. From the biosphere it goes into the lithosphere
through decomposition.
c. Then it will go through deposition when it goes
deeper down into the ground it takes the form of
fossil fuels such as oil, coal.
d. Then it goes through uplift and erosion. Uplift is
when the carbon gets pushed up due to geological
changes. Erosion is when water breaks down and
drags away bringing it to the hydrosphere.
e. Then algae and other photosynthetic organisms use
the CO2 and converts it to glucose in the biosphere.
f. The glucose is then consumed within the biosphere.
g. Through respiration glucose converts back to carbon
dioxide and reenters the atmosphere.
h. Other Examples of Movement – weathering,
volcanic activity, diffusion (from hydrosphere to
atmosphere and back again)
