These are characteristics of a wave.
Prokaryotic organisms fall under the Archaea and Bacteria domains. Prokaryotic organisms lack cell organelles and a distinct nucleus.
Prokaryotes are microscopic organisms from the two of the three main domains of life—Bacteria and Archaea—that are part of the domains of life. (The third eukaryote, eukarya, includes all eukaryotes, such as animals, plants, and fungi.) While the majority of eukaryotes are multicellular, bacteria and archaea are single-celled.
Prokaryotes do not have mitochondria or the majority of the other membrane-bound organelles that make up a eukaryotic cell, in addition to not having a nucleus. Prokaryotic organelles, including bacterial microcompartments, which are thought to be simple organelles enclosed in protein shells, have since been discovered. Previously, it was believed that prokaryotic cellular components within the cytoplasm were unenclosed aside from an outer cell membrane. Some prokaryotes, like cyanobacteria, can form substantial colonies despite being unicellular. Some have multicellular stages in their life cycles, like myxobacteria. Prokaryotes are asexual and do not fuse their gametes during reproduction, though horizontal gene transfer does occur.

Your answer will be A producer because producers are plants they give off food and a lot of animals eat their their at the bottom of the pyramid because that have nothing in defense also an ts not D because those are like lions, and bears stuff that eat things (like predators) also its not B because omnivores eat both plants and animals like bears and when it came down to rather A, or C I choose A because herbivores are animals that eat plants like a sloth.
Your answer is A.
Based on the 20 amino acids found in proteins, there are 6840 possible variations in a polymer composed of just three amino acids.
<h3>What are amino acids?</h3>
Amino acids are the molecules from which protein molecules are made from.
There are 20 common amino acids from which protein molecules are built up from.
The amino acids are joined one to another in the protein by peptide bonds.
In a polymer composed of three amino acids, the possible variations are calculated by permutation.
The possible variations are 20 permutation 3.
nPr = n!/(n - r)!
where n = 20 r = 3
nPr = 20!/(20 - 3)!
nPr = 6840
Therefore, there are 6840 possible variations in a polymer composed of just three amino acids.
