Answer:
Migration distance is inversely proportional to the fragment size,
Explanation:
Gel electrophoresis is a technique used in molecular biology that uses electricity to separate biological molecules based on size (DNA) or charge (proteins). For the DNA molecule, different sizes are separated from one another based on how fast they can migrate through the gel matrix.
In this technique, small fragments or sizes of DNA migrates farther than long sizes of DNA due to low friction in the matrix. In other words, the smaller the size of the DNA fragment, the farther the migration distance and vice versa. This shows that an INVERSE RELATIONSHIP exists between the migration distance and the fragment size in the electrophoresis procedure.
Answer:
atoms (2), community (11) , biome (13), biosphere (14), cells (5), organism (9), ecosystem (12), molecules (3), organ (7), organelles(4), organ system (8) , population (10), subatomic particles(1), and tissues (6)
Explanation:
Levels of organization in order from the simplest to the most complex are:
- Subatomic particles-neutrons, protons and electrons that make up the atom.
- atoms- Smallest particle of a substance that may or may not exist freely.
- molecules- two atoms combine to form molecule. e.g H₂
- organelles- organelles are functioning structures of a cell. e.g. Golgi apparatus.
- cells- organelles combine to form cell. e.g. Parenchyma cells.
- tissue- cells of similar origin and function form the tissue e.g. Cardiac tissue
- organ- tissues combine together to form organs. e.g. Heart
- organ system- many organs combine together to form system. e.g Circulatory system
- organism- several organ system combine to form an organism. e.g. Human being.
- population-organism of same species form a population.
- community- different population combine to form a community.
- ecosystem- communities live in a particular area and interact with the abiotic as well as biotic factors of that area to form ecosystem. e.g. pond ecosystem
- biome-A geographical area where several ecosystem sharing same abiotic factors thrive.e.g. tiaga biome
- biosphere- Narrow zone of the earth where the atmosphere , hydrosphere and lithosphere meet to support life.
