According to the Fick equation, the fish gill is an effective gas exchange surface because... A. It has a high blood-to-water diffusion distance B. The total surface area of the lamellae is very large C. The scaphognathite maintains a constant flow of water across the gill D. The gill tissue is supported by the surrounding water E. All of the above You are confronted with two creatures that, on first glance, both appear to be pill bugs. Upon closer examination, however, you note a difference that allows you to identify one specimen as a pill bug (an isopod crustacean) and the other as a pill millipede (a myriapod). That key characteristic is... A. The presence of an exoskeleton B. The presence of mandibles C. The presence of antennae D. The presence of branched appendages E. None of the characteristics listed above would allow an isopod crustacean to be distinguished from a myriapod Cleavage... A. Is a developmental stage consisting of a cell layer surrounding a fluid-filled space B. Is a specialized form of cell division that partitions the cytoplasm of a fertilized egg C. Refers to the fusion of haploid gametes to give a diploid zygote D. Produces an embryo with either two or three distinct cell layers E. None of the above
