• The main function of the digestive system is to take in food and break it down into nutrients that the body can use for energy and growth.
• Assimilation involves the conversion of absorbed nutrients into complex substances necessary for bodily functions. The other options are all part of the assimilation process.
• The kidneys are not part of the digestive system; they are primarily involved in the excretion of waste and regulation of electrolytes.
• The correct sequence of the digestive process can vary slightly, but ingestion, digestion, absorption, assimilation, and excretion are the key steps.
• The mouth is responsible for ingestion, where food is taken into the body.
• Bile production occurs in the liver, not in the large intestine.
• Digestion breaks down food into nutrients that the body can use for various functions, including energy production and cell repair.
• Mitosis is the process of cell division where one cell divides into two identical daughter cells.
• DNA replication occurs during the Synthesis (S) stage of interphase.
• This is the correct sequence of the phases of mitosis:

  Prophase - Metaphase -Anaphase- Telophase
• Meiosis results in the formation of four daughter cells containing half the original amount of genetic Information.
• Spermatogenesis is the process of sperm cell production, not egg cell production.
• Anaphase is the phase of mitosis where spindle fibers pull the chromosomes to opposite poles of the cell.
• Metaphase is when chromosomes align in the center of the cell.
• Mitosis results in two identical daughter cells.
• Meiosis occurs when a single cell divides twice to produce four cells containing half the original amount of genetic information.
• Animals are a vital source of food and materials for humans.
• Species is the smallest category of living organisms in the classification hierarchy
• The plant kingdom is important for various reasons, including oxygen production, water purification, and providing food
• Scientists use binomial nomenclature to name organisms, giving them a unique two-part name.
• "Familiaris' is the species name in the scientific name "Canis familiaris”
• Independent assortment is the principle that states the inheritance of one trait is not dependent on the inheritance of another trait.
• Carolus Linnseus is known as the father of modern taxonomy for his work in classifying organisms.
• Ecosystem diversity refers to the variety of ecosystems present in a given area.
• The plant kingdom is important for various reasons, including water purification, food provision, and oygen production.
• High biodiversity can make ecosystems more resilient to diseases, so this statement is not an advantage of high biodiversity.
• Tropical rainforests typically have the highest biodiversity due to their complex ecosystems and varied habitats.
• Biodiversity has importance in economy, culture, recreation, but not in history.
• Energy decreases as you go up the trophic levels in an energy pyramid.
• Biomass typically decreases as you move up trophic levels due to energy loss.
• Plants and animals play a crucial role in the oxygen-carbon cycle through processes like photosynthesis and respiration.
• Transpiration is the process by which plants release water vapor into the atmosphere.
• Biogeochemical Cycle - These cycles involve the circulation of elements through biological, geological, and chemical processes.
• Plants and animals both play key roles in the oxygen-carbon cycle through processes like photosynthesis and respiration.
• Bacteria play a key role in nitrogen fixation, nitrification, and denitrification, all of which are part of the nitrogen cycle.
• Mining typically results in soil disturbance and erosion, but it does not directly provide soil for planting.
• Wind turbines produce clean energy and do not contribute significantly to pollution.
• Recycling paper and cardboard helps reduce the demand for new materials, thus reducing the need for deforestation.
• Biomass energy, derived from organic materials, is a renewable resource.
• Conserving water helps mitigate the impacts of climate change, particularly on water resources.
