GEN 2 BIO

• BIODIVERSITY



  It is the variety of life found on Earth and it includes every living thing such as plants, bacteria, animals, and humans
• • GENETIC DIVERSITY


  It refers to the variation of genes within a species
• SPECIES DIVERSITY


  It refers to the variety, as well as the relative abundance, of species within a region
• POPULATION DISTRIBUTION


  Describes how the individuals are distributed or spread throughout their habitat
• ECOSYSTEM DIVERSITY


  It's is the variation among the group of organisms in different settings
• INDEX OF DIVERSITY


  It's is a mathematical measure of the community's diversity of species
• • CLUMPED
  • RANDOM
  • UNIFORM


  List down 3 examples of Population Distribution
• ENDANGERED


  It is when the number of species are limited or low
• species


  These are endangered to become endangered
• extinction 


  The last individual belonging to a particular species is gone forever
• Evolution


  It is defined as the change in gene frequency of a given population over time.
• Speciation


  It is the process through which a new species arises as a result of adaptation to an ever-changing environment.
• Allopatric Speciation


  It is speciation occurring in the presence of a physical barrier, such as a mountain range or a river, etc. In such a case, gene flow is blocked, and evolutionary agents work on the now-isolated population, resulting in new species.
• Adaptation


  These are structures or behaviors that increase the livelihood or fitness of an individual. Over time, structures and genetic frequencies shift so profoundly that a new species formed
• Convergent evolution


  It refers to the evolution in different lineages of structures that are similar or 'analogous', but that cannot be attributed to the existence of a common ancestor, in other words, the fact that the structures are analogous does not reflect homology.
• fossil record


  is a collection of fossils documenting the history of life on Earth. These fossils can teach us about an extinct organism's size, shape, and/or behavior. Extinct means that all members of a species or another grouping of organisms have died off.
• Sedimentary rocks


  These are formed from pre-existing rocks or pieces of once-living organisms.They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding
• Charles Darwin


  Whose theory is the Natural Selection?
• The Origin of Species


  What is the name of the book that Charles Darwin published in 1859?
• Which of the following is a reactant in photosynthesis?

• Which organelle is primarily responsible for photosynthesis in plants?

  Chloroplast
• What is the primary product of photosynthesis?

  Glucose
• Respiration


  Which process releases energy from glucose in the presence of oxygen?
• Mitochondria


  Where does cellular respiration primarily occur in eukaryotic cells?
• Oxygen


  Which molecule is the final electron acceptor in the electron transport chain during cellular respiration?
• Release of energy


  What is the primary purpose of cellular respiration in living organisms?
• water


  Which of the following is NOT a reactant in cellular respiration?
• Sunlight


  What is the primary source of energy for photosynthesis?
• Which part of the plant allows for gas exchange during photosynthesis?

  Leaves
