of the same # of nuetrons ? The atomic # is right element but different water molecule ? 2, hydrogen molecule a Difference between Covalent bond and Tonic bond? Toinic bonds are when electrons are tranferred from atom to the other. Covalent bond is shared by atoms insted of transferred. when electrons are one Why is Carbon important ? Carbon can form Kinds of bonds and form essential compounds What type of ion is formed when electrons ? A and a Lelectrons. atoms gain and loses positive ion is formed when it loses elections. is formed when the cetam gains negative ion * Polarity of water and where the particles are found? Water is polar because of the unevenly distrubted charges. The negative charge is near the molecule Oxygen and the positive charge is near the hydrogen molecule Difference between - Solvant and solote ? Substance A Solute is being dissolved while the Solvant is the the Solute dissolves. Sugar is solute. And water is which example example of Solvant. of a many influence a diff an How does What's an enzyme a catalyst? Enzyme decreases reaction. So it the activation energy of increases the speed, so it's a substance helpful in biological reaction. A catalyst is the speeds up a reaction without itself the rate of being changed. It lowers activation energy an a biological reaction? What is activation energy? Energy needed to get a reaction going What CO² + H²0 are are the reactants and products in the and H²CO³ is the prod reactants. Understand levels. of organization from smallest to laron and their definitions? Biosphere consist of all life on ou in which life exists, incl all parts of land, water, and the atmosphere. Biome - A group of climates and typical ecosystems that have the Earth and similar All the organisms (ex : Bavennab, grassland). Eco Systems + organisms that live together in a place with their physical enviroment (biotle and abiotic factors). Community. Several interacting populations that live together defind area. Population - of individuals that belong live in the same area. group to the same species and organisms - An individual animal, plant, or a single-celled life form. consumer ? A synonym kr producer is autotrophs and for: consumer it is heter troph Synonym for producer and What Is a producer how does it gain it's energy, what is the primary way they get their energy? A producer is an autotroph, of a self feeding organisms. They energy by using dight energy to build sugars out of carbon dioxide (photosynthesis) or the energy can obtain (² Stored in Chemical bonds are used as fuel (chemosynthesis). Primary producers obtain energy from Sunlight from nonliving sources cauto trophs), and other primary producers obtain energy from consuming living Cheter trophes and materials. or dead matter organic Examples of producers ? plants, bacteria, androlgen. between food web and food chain ? Diffrence Food chain is a series of steps in which organisms transfer energy by eating and being eaten. A food. all of the food chains in an ecosystem web links together Understand effects. the ecosystem if an organism removed from the food chain ? If an organism is removed from the food chain then the other is organisms would be affected by the change. How much to the where energy other. ? consumer On is transferred from one organison of energy is passed... 10% do you the lowest energy in find the greatest amount of energy a food chain ?. You can and find the greatest amount of energy comes from the producer from the 3rd and the least amount of energy comes level abiotic What is the base of auto trophs / primary producers An example of On all ecological pyramids? The ? Bacteria of fungi. Define and biotic factors ? Give examples ² Biotic factors when any living organism is inhabiting the Earth Ex. animals, Plants, mushrooms, and bacteria. Abiotic factors- the non- living Part of the enviroment. Ex. sunlight, heat, Precipitation, and humidity. decomposer 2 who are the three. types Wht is symbiosis Symbiosis relationship? Symbiosis two species that live close association with one another. The 3 symblesis mutualism, commen salism, and parasitism. relationship is Relationship Characters ane examples of each symbiotic relationship Commen Salism - when I benefits and the other is neither" harmed nor benefit, ex. relationship between Mutualism- when both species benefits, ex. between zooplankton and whale. Parasitism- when I benefits the other is harmed, ex. Relationship between ticks & fleas and animal fur like dogs, coyotes, and wolves. and Benefits of the microscope? Scientists can structures cells, bacteria, and many other Small to the eye now Study that are to microscope? Hold the Correct to handle the way microscope with one hand around the arm of the device, and the other hand under the base. What is cell theory? States that all living things are I made of cells, cells are the basic units of structure 2 function in living things, and exsiting cells. new cells are Produced from Organelles found Chloroplast & cell wall found in plant cell but not animal cell 2 What is isotonic Solution? Difference between hypotonic and hypertonic Solution ? Isotonic solution lis solution that has the same osmotic some other solutions. Hypotonic osmotic a pressure Solution - area. Pressure than a particular a lower Hypertonic Solution- having a higher osmotic pressure than a particular area. Vocab Hypothesis - Scientific ations that can be tested having What does Chargaff's rule state regarding the percentages of bases ? What does the rule State regarding the base pairing? Chargaff's rule stake that DNA from any species of any organism shoid thave. a lil ratio. So guanine and cyto sine should be equal and adenine and guanine shold Chargaff's rule also state adenine always pair with guanine. And thymine always pair with cytosin be equal. that What did Rosaline Franklin, Watson & crick determine regarding the DNA molecule? They discovered that the DNA'S structure is a double helix. explanation for a Set of obser in ways the Support or inject Bias - A particular preference or Pov that is personal, rather than scientific Compound 2 or more elements chemically combined Difference between Prokaryotes ane eukaryotes 2 ? Prokaryotes have no nucleus and more simple and small, ex, bacteria cell, Eukaryote cell has a nucleus and is larger and more complex, ex. animal cell and plant cell. COL Know functions of organelles ? Nucleus - contains most of the cell's DNA Golg; Apparatus - modifies, sorts, and packages proteins and other materials from the ER for Storage in outside of cell. Smooth ER- in plasma membranes, the cell or release synthesizes lipids, Phospholipids as and steroids. Rough ER- involved in the synthesis of proteins___ Ribosomes- makes proteins. Mitochondria- generates most chemical energy needed to power the cell's bio- Chemical reactions. Cell membrane - transport nutrients into of the cell fout of the and cell. It tection for the cell. Give example is also to transport toxic substances. also provides support and pro- Difference between passive Active transport mares molecules and ions concentration and active transport ? from lower Concentration. to higher with the help of energy in the form of ATP. Passive transport moves molecules and ions from a higher concentration to lower concentration. without energy. What is osmosis? Osmosis is the diffusion of water through a selectivly Permeable membrane..
