Humans and cats with an extra sex chromosome (XXY) might share the characteristic of sterility (can't have offspring).

This is because conditions like Klinefelter syndrome in humans (which corresponds to the XXY configuration) often lead to reduced fertility or sterility. Similarly, extraneous sex chromosomes in other species can also impact fertility, though the specifics can vary by species.

The other options – albinism and extra limbs – are not directly related to the presence of extra sex chromosomes. Moreover, the statement that "humans with an extra sex chromosome don't usually survive past birth" is incorrect, as many can survive but may face various health challenges.

To accurately determine what the picture depicts, I would need to see the image. However, I can provide some general characteristics of each category:

  • RNA: Usually single-stranded, made up of nucleotides containing ribose sugar and the nitrogenous bases adenine (A), uracil (U), cytosine (C), and guanine (G).

  • DNA: Typically double-stranded, forms a double helix, made up of nucleotides containing deoxyribose sugar and the bases adenine (A), thymine (T), cytosine (C), and guanine (G).

  • Carbohydrate: Composed of carbon, hydrogen, and oxygen, usually in a ratio of 1:2:1; can appear as simple sugars like glucose or more complex forms like starch.

  • Protein: Made up of amino acids linked by peptide bonds, can take many shapes and forms, often depicted as a chain or folded structure to indicate the tertiary or quaternary structure.

If you could provide a description of the image or its key features, I could give you a more accurate answer!
