Answer:
about the Trilobites is =Trilobites ( /ˈtraɪləˌbaɪt, ˈtrɪ-, -loʊ-/;[4][5] meaning "three lobes") are a group of extinct marine artiopodan arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years.[6] . and about the algae is =Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.

Answer:
tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).
Explanation:
A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.
What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.
