I’m pretty sure the answer is A or c
I hope this helps narrow down choices
Answer:. __C__ I am useful for a fast source of energy. 2. __P__ I have involvement in the immune system (ex: antibodies). 3. __L__ I am helpful for long term energy storage. 4. __P__ I have a large role in muscle development. 8. ___P_ Enzymes, which can speed up reactions, belong in my category. 11. __N__ My category includes genetic material. 9. __L__ I am important for insulation. 5. ___C_ If athletes "pasta load," they consume a lot of me. 7. __P__ I make up cell membranes. 6. __N__ A mutation in DNA would initially start with me. 10. ___C_ I contain elements C, H, and O and have a ring-like structure. 12. __L__ I can contain long fatty acid chains.
Answer:
Asegment of chromosomal DNA
Explanation:
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes. It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person's unique physical features.
For the first question, a unicellular eukaryote with autotrophic features (meaning it can produce its own food) will be from either Domain Bacteria and Domain Eukarya, but since Domain Bacteria is not in the choices, then Domain Eukarya is the answer. Domain Archaea are yes, unicellular organisms, but they are not eukaryotes and they do not possess autotrophic features. Domain Eukarya have photosynthetic protozoans (i.e. Diatoms).
For the second question, in Kingdom Fungi, you chose that fungi can either be unicellular or multicellular, which is true, for instance yeast and mushrooms respectively. Fungi are heterotrophic as they cannot produce their own food. The other answer is that fungi are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.
For the third question, in Kingdom Protista, you chose that protists can either be unicellular or multicellular, and this is true in the case of amoebas and kelp respectively. Protists can be both heterotrophic and autotrophic. The other answer is that protists are eukaryotic organisms since their cells have a true nucleus and they belong to Domain Eukarya.
