Chapter 31, Problem S1.2BYB
Summary Introduction
To analyze:
What is the basis for classifying an organism as a member of kingdom Animalia?
Introduction:
The organisms on Earth were classified into five kingdoms - Prokaryote, Protista,
Expert Solution & Answer
Explanation of Solution
Living organisms are classified into five kingdoms- Prokaryote, Protista, Fungi, Plantae, and Animalia. Animalia is also termed as Metazoa.
The general characteristics of Animalia kingdom are
- It should be a eukaryote
- It should be a heterotroph
- It should be multicellular having nucleus, mitochondria, Golgi complex, ribosomes, lysosomes, vacuoles, cytoskeleton.
- It should contain a muscular system, skeletal system, circulatory system, excretory system, and reproductive system, to perform various functions required for survival.
- It should be able to ingest food and digest it inside the cavity.
- It should be able to move independently.
- It should contain organs necessary for the gaseous exchange of gases like oxygen and carbon dioxide necessary for survival.
Conclusion
The kingdom Animalia is characterized by eukaryotic and heterotrophic organisms. It is multicellular and has cell walls. They depend on plants directly for their food. Food is ingested and digested in the food cavity. The organisms are capable of locomotion.

- If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.arrow_forwardYou aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?arrow_forwardYou decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.arrow_forward
- You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.arrow_forwardDesign a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity.

- A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.
