Suppose that a geneticist was attempting to determine the nature of the genetic code. the geneticist conducts an experiment to determine if the genetic code contains triplets or doublets and if the genetic code is overlapping and nonoverlapping. in the images below, each circle represents an amino acid in a polypeptide sequence, with the different colors representing different amino acids. match the types of polypeptide that the scientist predicts would be produced by different reading frames from the sequence 5\'-tctctctctctc-3\' to the associated genetic code hypothesis. more than one polypeptide may be possible for each reading frame type.

Ameadow ecosystem includes many species of grasses and small shrubs, several herbivores, and a few carnivores. a fungus colonizes the meadow and kills most of its vegetation. what is most likely to happen to the populations of herbivores and carnivores in the ecosystem? a. the populations of herbivores and carnivores will increase because there will be less competition for chemical energy. b. the populations of herbivores and carnivores will remain stable because the fungus cannot infect these organisms. c. the populations of herbivores will decrease because of vegetation loss, but the population of carnivores will remain stable. d. the populations of herbivores and carnivores will decline because less chemical energy will be stored in the ecosystem.

How is mitosis different in plants and animals? a. in animals, the cell membrane pinches together. b. in plants,the dna is one circular chromosomes. c. in plants, there are no sister chromatids. d. in animals, a new cell wall forms.

As a small change in a person's dna can cause a genetic disorder
