Where would you look if you had to find a cycliophoran?
Expert Solution & Answer
Summary Introduction
To determine: The criteria to look for in order to find a cycliophoran.
Introduction: In crustaceans such as crayfish, a saclike organ called statocysts occurs that opens to the surface by a dorsal pore and is present on the basal segment of the first antennae. This organ is a balancing organ that contains a ridge bearing sensory setae that are formed from the chitin lining of the sac.
Explanation of Solution
The cycliophoran are the organisms that have been recently discovered and have a very peculiar habitat. The cycliophorans dwell on the mouthparts of the marine decapods crustaceans in the Northern hemisphere and therefore, can be precisely found. They attach to the bristles on the mouthparts with an adhesive disc on the end of the acellular stalk. The feeding habit of these organisms is that they collect bacteria or bits of food that are dropped from their lobster host, on a ring of compound cilia that are present around the mouth.

What objects or events has the team chosen to analyze?
How does your team wish to delineate the domain or scale in which these objects or events operate? How does that limited domain facilitate a more feasible research project?
What is your understanding of their relationships to other objects and events? Are you excluding other things from consideration which may influence the phenomena you seek to understand? Examples of such exclusions might include certain air-born pollutants; a general class of water bodies near Ottawa, or measurements recorded at other months of the year; interview participants from other organizations that are involved in the development of your central topic or issue.
In what ways do your research questions follow as the most appropriate and/or most practical questions (given the circumstances) to pursue to better understand…
The Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2).
Which of the following claims is most consistent with the data shown in Figure 2 ?
A Esp expression is necessary to prevent the overproduction of insulin.
B Esp protein does not regulate blood-s
