A. FAMILY, GENUS, SPECIES, SUBSPECIES.
The complete and correct hierarchy of taxonomic groups from largest to smallest are:
1) Domain
1.1) Archaea 1.2) Bactera 1.3) Eukarya
2) Kingdom
2.1) Animalia 2.2) Plantae 2.3) Fungi 2.4) Protista 2.5) Archaea 2.6) Bacteria
3) Phylum - has 35 phyla
4) Class
5) Order
6) Family
7) Genus
8) Species
Answer:
Desert they adapted to survive in the desert
Archaea actually are a domain! Originally they were thought to be bacteria, but have since been classified in their own domain: archaea.
Answer: Proteins and carbohydrates
Explanation: Functions of a protein include building, repair, and recovery of tissues in muscle, skin, organs, blood, hair, and nails. While
Carbohydrates supply your body with quick available energy and some examples are breads, grains, and pasta.
Answer:
The correct option is D. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
Nitrogen is an active constituent of amino acids which make up proteins. Nitrogen is also an active constituent of the nitrogenous bases which make up an organism's DNA.
Phosphorus is actively present in the DNA but amino acids lack phosphorus.
Our body is actively made up of DNA and proteins. If the nitrogen was radioactively labelled, the experimental results would be wrong as proteins also have nitrogen in them.
