Question 1
1.

If each of our cells contains the same genetic instructions, how are our bodies able to form specialized cell types and organs? Be sure to use the terms transcription and translation in your response.

Feel free to respond, "I don't know yet," or leave the question blank if you are unable to answer at this time.

Research conducted by UC Berkley states:
- 78% of carbon in American bodies comes from corn.
- In France, only 15% of carbon comes from corn.
Research supports most of our dietary intake is comprised of carbohydrates and lipids.
- The American Happy Meal, for example, is made of 72% carbohydrates, 16% lipids and
12% proteins.
- Less than 1 % of the human body mass composition is nucleic acids.

Explain using the information given above why there is a difference between the macromolecules consumed by Americans and the elemental composition of the human body (shown in the diagram below).

The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.

Select the options that correctly complete the following statements regarding the cycling of carbon.

Glucose is an example of carbon stored in the __________, while carbonic acid is an example of how carbon can be found in the __________.

Carbon can be stored in the Geosphere in the form of __________ but it is found in the atmosphere as __________

fat
starch
glucose

How do multicellular organisms form from a single cell (zygote)?
The organism undergoes cellular division but not differentiation
The organism undergoes both cellular division and differentiation
The zygote changes into many different cell types before division occurs
The zygote can divide or differentiate depending on the genetic code

Why is anaerobic respiration adventageous to some organisms?
They may live in an environment that is oxygen poor and need to extract energy from their food
They may live in an oxygen rich environment and use it to generate ATP
They may live in an environment that is oxygen poor and require alternate nutrient sources
They may live in an oxygen rich environment and require alternate nutrient sources
I don't know yet
What part(s) does photosynthesis and cellular respiration play in the carbon cycle?
Select all that apply:
Cellular respiration captures carbon dioxide from the atmosphere
I don't know yet.
Photosyntheis releases carbon dioxide into the atmosphere
Cellular respiration releases carbon dioxide into the atmosphere
Photosynthesis captures carbon dioxide from the atmosphere
How can genetics be used to explain why some offspring have traits that are not like the traits of their parents?
Sometimes mutations occur that generate new phenotypes
I don't know yet
Some traits are dominant and are more likely to be passed down than recessive ones
Errors in meiosis can create new combinations of traits
Some traits are recessive and could present in the offspring while remaining unseen in the parents
Given the Punnett Square, what percentage of the offspring have the genotype rryy?

4%
6.25%
12.5%
25%
I'm not sure how to calculate percentages of genotypes given a punnett square yet.
