Answer 3

The major levels of structure in the universe, from smallest to largest, are:

  1. Subatomic particles and fundamental forces: This level encompasses particles such as quarks, electrons, and neutrinos, as well as the fundamental forces like gravity, electromagnetism, the weak nuclear force, and the strong nuclear force.

  2. Atoms: Atoms are composed of a nucleus containing protons and neutrons, surrounded by orbiting electrons. These particles are held together by electromagnetic forces.

  3. Molecules and compounds: Molecules are formed when atoms bond together through chemical reactions. Compounds consist of molecules composed of different elements.

  4. Cells: Cells are the basic structural and functional units of living organisms. They vary widely in structure and function, but all cells share certain characteristics, such as the presence of genetic material and the ability to metabolize nutrients.

  5. Tissues: Tissues are groups of cells that work together to perform specific functions. Examples include muscle tissue, nervous tissue, and epithelial tissue.

  6. Organs: Organs are composed of different types of tissues working together to perform specific functions within an organism. Examples include the heart, lungs, brain, and liver.

  7. Organ systems: Organ systems are groups of organs that work together to perform complex functions necessary for the survival of an organism. Examples include the cardiovascular system, respiratory system, nervous system, and digestive system.

  8. Organisms: Organisms are individual living entities capable of carrying out life processes such as growth, reproduction, and response to stimuli. They can range from single-celled organisms like bacteria to complex multicellular organisms like plants and animals.

  9. Populations: Populations consist of groups of organisms of the same species living in the same area and interbreeding. They form the basic unit of ecological study.

  10. Communities: Communities are composed of populations of different species living and interacting with each other in a particular habitat or ecosystem.

  11. Ecosystems: Ecosystems consist of all the living organisms (biotic factors) in a particular area, as well as the non-living components (abiotic factors) such as soil, water, and climate. They function as complex, interconnected systems.

  12. Biosphere: The biosphere encompasses all the ecosystems on Earth and includes all living organisms and their environments. It represents the highest level of organization in the universe that supports life.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
