Chapter 28, Problem 1TY
Summary Introduction

Introduction: Cell signaling is one of the important features observed in the animal cell. The animal cells communicate with each other by the mechanism of direct cell-to-cell contact. Scientists discovered that the multicellular animal cells have evolved from an ancient unicellular organism.

Answer to Problem 1TY

Correct answer: Choanomonada can be used to study the evolution of cell-to-cell signaling mechanism in animal cells. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Choanoflagellates, also known as Choanomonada, are eukaryotic organisms. These organisms are believed to be the species that have closest association with the multicellular organisms (especially animals). Choanomonada and animals have a similar cell-to-cell signaling mechanism. Therefore, Choanomonada can be used to study the evolution of animal-specific cell-to-cell signaling system.

Option c. is given as “Choanomonada”.

The group that can be used to study the evolution of animal-specific cell-to-cell signaling mechanism is Choanomonada. Hence, the correct answer is option c.

Reasons for incorrect answer:

Option a. is given as, “Rhodophyta”.

Rhodophyta is also known as red algae and they are able to perform photosynthesis. Photosynthesis is a process observed in plants and not in animals. This indicates that Rhodophyta represents a close association with plants. They cannot be used to study the animal-specific cell-to-cell signaling system. Hence, option a. is incorrect.

Option b. is given as, “Excavata”.

Excavata cannot be used to study the evolution of cell-to-cell signaling mechanism in animal cells. This is because, they include both photosynthetic and heterotrophic organisms. They do not resemble animal cells as animals do not perform photosynthesis. Hence, option b. is incorrect.

Option d. is given as, “Radiolaria”.

Radiolarian lives in an aquatic habitat and they are heterotrophic in nature. They cannot be used to study the evolution of cell-to-cell signaling system as they do not share similarities with the animal cells. Hence, option d. is incorrect.

Option e. is given as, “Chlorophyta”.

Chlorophyta is also referred to as green algae. They contain the same photosynthetic pigments that are present in the plants. Chlorophyta performs photosynthesis and shows a close association with plants and not animals. They cannot be used to study the animal-specific cell-to-cell signaling system. Hence, option e. is incorrect.

Hence, the options a., b., d., and e. are incorrect.

Conclusion

The group that can be used to study the evolution of animal-specific cell-to-cell signaling mechanism is Choanomonada. This is because, they show a close association with animal cells.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
