It has been pointed out that studies
done on rats resulted in large livers and spleens. What are the benefits
and the limitations of testing products for people on lab animals? How do
you compare this to the benefits and limitations of testing these products on
Our first module discusses atoms,
molecules and levels of organization. How do the lipids we are discussing
fit into this organization? What are they made of and then what is that
made up of?
Please explain why a large sample
size and identifying characteristics of the mothers and “controlling”
them is so important.
Please pick 1 element from the
periodic table. Tell us it’s atomic weight, atomic number, and the number
of protons, electrons and neutrons an atom of this element has. Please
also discuss whether or not this element, either alone or as part of a
molecule, is used by the human body and in what way. Is it something we
need in order to survive? If so, is it found in any foods we eat?
Add a picture of your element if you’d like!
How do we know that the benefits
from the breastmilk are coming from the actual liquid itself rather than from
the feeding method? Could it be possible that it’s the lip on skin that
is causing the increases seen in vision and IQ?
Please pick one of these terms and
tell us about it. Please explain where it fits in the organizational
scheme (if applicable) and include a photo, picture, diagram or video to
demonstrate the term. Please write the name of the term in the title and
only use each term once.
Some students make a distinction
between synthetic DHA and natural DHA. Is the chemical formula of DHA
different when it is extracted or synthesized by a human rather than found
What about water? What is the
chemical formula of water? Is there a difference in the chemical formula
of water when it is found naturally in rain or the ocean as opposed to
scientists in a lab synthesizing water?
What is the independent/experimental
variable in the experiment you reviewed? The dependent variable?
The experimental group? The control group? What are some controlled
What about the DHA and ARA
themselves? How do we know it is those specific lipids and not something
else that is in breastmilk or the combination of chemicals found in breastmilk
that lead to the benefits we’ve seen from adding them to formula?
