Question

Review the graph that represents the whole class data. Compare the food energy in the saltine and pretzel with that of the pecan. Which of these answer choices would NOT be a valid conclusion?
A) The pecan contains molecules with more complex chemical bonds than does the saltine and pretzel.
B) The saltine and pretzel contain carbohydrates; the pecan contains lipids, proteins and carbohydrates.
C) The fats and proteins in the pecan provide more chemical energy because there are more chemical bonds to break during digestion.
D) The saltine and pretzel are made of flour, yeast, and baking soda, and salt. The pecan contains no flour but it does contain fats.

Answer 1

Answer:

The fats and proteins in the pecan provide more chemical energy because there are more chemical bonds to break during digestion.

Explanation:

Saltine and pretzel are baked snacks while pecan is the seed of pecan tree consumed as food. The pecan tree is usually found in Mexico. Saltine is a salted cracker snack made of white flour, yeast and baking soda and salt. It has a salty taste and its place of origin is the US.

Pretzel is a snack made of flour, baking soda, yeast and snack. Its origin is in Germany before long years. Since the snacks pretzel and saltine are made of flour they contain carbohydrates. In pecan seeds fat is present in the highest proportion.

Answer 2

Answer:

Option-(A) is the best choice to choose from.

Explanation:

• As the pecan seed are consist of unsaturated fatty acids at some stage while they also posses some protein molecules in the later stages of development. So, they do have a complex molecular structure. Just as the carbohydrates in the saltine and pretzel have a complex molecular structure.
• Both, the material are very high in energy but as pecan seeds are very high on energy and they posses a lot more energy as compared to the later two.
