E) Secrete the exoskeleton in insects. 17, Which is true concerning animal viruses? A) Lack an envelope when they leave the host cell. 8) Attack the host cell by exocytosis. C) Have an outer coat of nucleic acid. Some have RNA genomes. E) All of the above. D)Explanation / Answer
12. b. The ability of cells isolated from the early embryo to develop into viable individuals
Cells that undergo indeterminate cleavage are equipotential in nature and each has the ability to develop into a new individual as their developmental fate is not determined.
13. e. Both A and C
Lytic cycle of viruses takes place in side the host cell, where the virus takes control of the cell's replication and transcription processes thereby producing viral DNA and proteins after which it lyses the host cell and releases the newly produced viruses.
14. E. Nonmotile and parasitic
All apicomplexans are parasitic and they lack locomotor processes like flagella, cilia and pseudopods.
15. c. A fungal cell containing genetically different nuclei
Heterokaryon refers to a multinucleate cell that contains genetically different nuclei. In fungi, it occurs during sexual reproduction.
16. d. function in excretion in insects
Malpighian tubules are slender tubes found in the posterior regions of the arthropod alimentary canal. The main function of the Malpighian tubule of insects is the excretion of nitrogenous products and the remains of other metabolites.
17. d.Some have RNA genomes
Animal viruses contain DNA or RNA as the genetic material packed inside a capsid made of proteins. They enter the host cell by means of endocytosis where they replicate and produce copies of themselves and gets released in the enveloped form.
