To discuss: The important distinguishing features of arthropods.
Introduction: Arthropods are the protostomes and belong to the ecdysozoan branch. More than ¾ of all known species belong to this group. Arthropods have specific features that allow them to inhabit a wide range of habitat.

Explanation of Solution
Arthropods are bilaterally symmetrical, triploblastic organisms with an organ system level of body plan. They have a complete digestive tube. Presence of a segmented body, a hard exoskeleton composed of chitin and protein, and the paired jointed appendages are the characteristic features of arthropods. The appendages are modified for various functions such as swimming paddles, walking legs, mouthparts, and sensory organs.
The nervous system consists of a brain and ventral nerve cord with ganglia. Some arthropods such as insects and many crustaceans have compound eyes composed of many light-sensitive units called ommatidia. Arthropods have an open circulatory system and a dorsal, tubular heart. Arthropods have gills, tracheae, or book lungs for breathing. They have a complete

Thank you!arrow_forwardplease draw in and fill out the empty slots from image below. thank you!arrow_forwardThere is a species of eagle, which lives in a tropical forest in Brazil. The alula pattern of its wings is determined by a single autosomal gene with four alleles that exhibit an unknown hierarchy of dominance. Genetic testing shows that individuals 1-1, 11-4, 11-7, III-1, and III-4 are each homozygous. How many possible genotypes among checkered eagles in the population?arrow_forward

Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forward
