Answer 1

Here are the answers to your questions based on the information provided:

Question 1:
d - photosynthesis and cellular respiration

Question 2:
b - carbon cycle

Question 3:
b - 90%

Question 4:
It is impossible to select an answer without seeing the images, but generally, the answer would relate to the specific kilocalorie values shown in the energy pyramid in the images provided.

Question 5:
a - producers

Question 6:
a - The fish contains energy from photosynthetic plants.

Question 7:
Again, it is impossible to answer without seeing the diagram. However, if W represents a stage where nitrogen is converted, a potential answer could be: a - Its unusable form is converted into a form that is usable by bacteria in the soil.

Question 8:
c - secondary consumers

Question 9:
Similar to Question 4, it is impossible to select an answer without seeing the images. A general answer would be based on the distinguishing characteristics outlined in the images.

Question 10:
If you have a DNA sample, Guanine (G) should correspond to Cytosine (C) due to base pairing (A with T and G with C). Assuming the percentage of Adenine (A) is given and matches those of Thymine (T) as well as Cytosine (C) and Guanine (G), look at the total percentages. If A is 17%, then G should also be a - 17% (if the total relationships hold). If the percentage for N is stated explicitly, please use that information.
