Question

1. which of the following is an example of quantitative data?

a. the color of the leaves
b. the height of the plant in centimeters
c. the smell of the flowers
d. the texture of the soil

1. which of the following best describes the process of evolution?

a. the extinction of species that cannot adapt to their environment
b. a gradual change in species over time through genetic variation and natural selection
c. the creation of new species through artificial selection
d. a sudden transformation of species due to environmental changes

1. what occurs during protein folding?

a. a protein adopts a specific 3d structure
b. a ribosome assembles amino acids
c. a polypeptide chain is synthesized
d. rna is transcribed from dna

Explanation:

• For question 20: Quantitative data is numerical. The height of a plant in centimeters is numerical, while color, smell, and texture are qualitative.
• For question 21: Evolution is defined as a gradual change in species over time through genetic variation and natural - selection. Extinction is a part of the process but not the full definition. Artificial selection creates new varieties but not the same as natural evolution. Sudden transformation is not how evolution typically occurs.
• For question 22: Protein folding is the process by which a protein adopts a specific 3 - D structure. Ribosome assembles amino acids during translation, polypeptide chain synthesis is part of translation, and RNA transcription from DNA is also part of gene expression but not protein folding.

Answer:

1. B. The height of the plant in centimeters
2. B. A gradual change in species over time through genetic variation and natural selection
3. A. A protein adopts a specific 3D structure
