Question description

HW 1

Q1: Formulatea null hypothesis for the following hypothesis: ‘’Tomato plants
exhibit a higher rate of growth when planted in 
compost instead of in soil. “Why is the null hypothesis useful?
Q2: Describe the
characteristics of questions that can be addressed through the scientific
method, and give some examples.
Q3: Design an experiment
using al the steps of the scientific method.
Does the statement “ evaluation is just theory” have any merit? Explain?

HW 2

Q1:  Explain how the shapes of carbohydrates,
lipids, and proteins relate to their function.
Q2:  describe the three types of particles that
comprise all atom in terms of charge, mass, and
location within the atom.
Q3:  discuss the basic steps of how an enzyme
catalyzes a reaction, using lactase as an example.
Q4:  compare and contrast DNA and RNA in terms of
structure, composition, and function.

HW 3

Q1:  describe how the properties of the head and tail ends
of the phospholipid molecules account for their specific arrangements that form
the bilayer.
Q2:  compare and contrast the theories of
endosymbiosis and invagination and the supporting
evidence for each

Q3:  a drop of red food coloring is added to a glass of
water. After a few months, the entire glass of water is evenly dyed red. What
role did diffusion play in this experiment?
Q4:  define passive transport, and explain what type of
passive transport would be used to move each of the following substances into a
cell: oxygen, amino acid, and water.

HW 4

Q1:  describe the movement of protons as electrons are
shuttled through the electron transport chain and as the energy in this
gradient is used to form ATP.
Q2:  briefly describe the adaptations of C4 and CAM plants
that reduce water loss through stomata.
Q3: cellular
respiration is a lot like photosynthesis in reserve. “Evaluate this statement,
and discuss the similarities and differences between photosynthesis and
cellular respiration.  
Q4:  Briefly describe the two laws of
thermodynamics and how they related to cellular respiration.
Q5: How is a hydrogen bond similar to an ionic bond? How
are they different?
