All organisms consist of structural units called cells; some contain a single cell (unicellular) and others contain many units (multicellular). Multicellular organisms are able to specialize cells to perform specific functions. Organisms have both internal and external macroscopic structures that allow for growth, survival, behavior, and reproduction.. All living things are made up of cells. In organisms, cells work together to form tissues and organs that are specialized for particular body functions.
Answer:
The correct answer is C. The tertiary structure of a polypeptide is the overall three-dimensional shape of a fully folded polypeptide.
Explanation:
A polypeptide is a molecular chain composed of at least 10 amino acids (which are the molecules that make up proteins). When we talk about its tertiary structure, it refers to the complete overall three-dimensional structure of the polypeptide units of a given protein, where the polypeptide chain is fully folded and compacted. This folding is facilitated by unions called disulfide bonds, which are created from the cysteine residues, these bonds (called disulfide bridges as well) help to stabilize many polypeptides.
Answer:
A. Scientists discovered chromosomes and DNA.
Explanation:
Mendel's ideas were based on patterns of inheritance in plants. Although he identified these patterns, at the time, we did not know what the hereditary material was. This means Mendel couldn't uncover the mechanism of why he was seeing the patterns he was.
When scientists discovered chromosomes and DNA, they were able to see how Mendel's observations made sense in the context of DNA and chromosomes.
