C- carbon, h -hydrogen, 0- oxygen
Answer:
The correct answer is c. A:C
Explanation:
Thymine and guanine are most stable in their keto form and adenine and cytosine are most stable in their amino form. Sometimes these bases undergo tautomeric shift(proton shift) which converts them into rare less stable form called tautomeric form which are imino and enol form.
In this rare form, these bases can pair with the base which are not complementary to them. Like adenine base pairs with cytosine and guanine base pairs with thymine when present in rare form.
When these tautomeric forms of nucleotides incorporated in DNA they may cause mutation in the DNA.
Therefore the correct answer is c. A:C

Explanation:
You will notice that a plant cell has a cell wall, whereas animal cells do not have a cell wall.
The image given is incomplete. The complete image is attached below.
Answer:
A. A Squirrel, robin, and field mouse
Explanation:
Food web is defined as the interconnection between different food chains which shows how organisms from different food chains are connected with each other for food in the ecological community.
In the attached image, there are three consumers which depend on the same producer for food. Those three consumer are squirrel, robin, and field mouse feeding over plant seeds (producer) for survival.
Hence, the correct option is A.
