DNA, cell membrane, cytoplasm, and ribosomes.
Both prokaryotic and eukaryotic cells have structures in common. All cells have a cell membrane, ribosomes, cytoplasm, and DNA. The cell membrane, or plasma membrane, is the phospholipid layer that surrounds the cell and protects it from the outside environment.
Answer:
B. Smaller fragments travel faster and farther than larger fragments.
Explanation: Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving. [2] Proteins are separated by charge in agarose because the pores of the gel are too large to sieve proteins.
Lipids are a class of organic compounds, which suits best under the column macromolecules on the hierarchy of biological organization.
Biological organization refers to the hierarchy of composite biological systems and compositions, which illustrate life using a reductionistic method. The conventional hierarchy moves from an atom to more complex biospheres.
Each of the level in the hierarchy signifies an enhancement in the organizational complexity, with each component being mainly comprised of the previous basic unit level.
Answer:
Explanation:
The fossil record
This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.
