PART D – Long Answers [Lots of different questions to answer]
1. Trace the path of a drop of blood as it travels through your circulatory
system to the lungs to pick up oxygen and to your cells. Start at the vena
cava, discuss what happens to the blood at the lungs and as it passes by the
cells of your body. What role does diffusion play in this process and what
substances are being diffused? You name the organs of the circulatory
system in order as the blood would flow through them. [ /8]
2. Explain the life cycle of a sexually reproducing plant. Include in your
explanation, how a plant is pollinated and what happens after fertilization.
Include germination and the requirements for this to happen. Include a
diagram. [ /6]
3. A glassful of milk contains lactose, proteins, butterfat (lipids), vitamins
and minerals. Explain what happens to each component in your digestive
tract. [

4.
Compare the circulatory system of representative organism from
phylum Annelida and phylum Arthropod. Describe similarities and
differences. Which organism is more complex? Explain your reasoning. [

5. Humans and insects are often said to be the dominant animals on Earth,
and yet there is only one species of humans but over seven hundred thousand
species of insects. How would you explain this?
6. Describe the type of investigation that scientists could use to gather
evidence about what nutrients plants need in order to grow.
7. Explain what diversity is. What are the three types of diversity? Describe
a scenario in which diversity is being affected by humans (negatively or
positively). What role do humans play in impacting this diversity? Explain
how they are negatively or positively impacting diversity and what type of
diversity they are impacting.
