1. A way of learning about the natural world, it is also the knowledge gained by exploring the natural world.
2. A deal with descriptions that cannot be express in numbers.
3. Involves creating representations of complex objects or processes and helps people to study and understand things that are complex or that can’t be observed directly.
4. To consider the diverse ways in which scientists study the natural world and proposes explanations based on evidence they gather.
5. Processes to try answer the question. It is a possible explanation for a set of observations or answers to a scientific question.
6. An important part of the scientific inquiry process. It's the sharing of ideas results and experimental findings with others through writing and speaking.
7. It is how people change the world around them to meet their needs ands solve practical problems.
8. What to do in case of burns during any scientific investigation in the lab?
9. It is the basic unit of structure and function in an organism.
10. It is the organism to be composed of many cells that are specialized to do certain tasks?
11. It is the process of changing what occurs during an organism´s life to produce a more complex organism.
12. The organisms that make their own food are called:
13. The organisms that cannot make their own food are called:
14. To keep internal conditions just right for cells to function:
15. In the mid-1800s, a French chemist designed some controlled experiments that demonstrated that new bacteria appeared in broth only when they are reduced by existing bacteria.
16. In the 1600s, an Italian doctor desiged a controlled experiment to disprove spontaneous generation.
17. In 1590 he invented the first compound of the microscope. It was a tube with lens at each end.
18. In 1674 he invented the simple microscope. It used only one tiny lens, it could magnify a specimen up to 266 times.
19. He was the first to build a compound microscope to observe cells.
20. In 1663 he observed the structure of a thin slice of cork and found that it was made up of cells. Concluding that all plants are made of cells.
21. Concluded that all animals are made of cells.
22. Proposed “All cells come from cells”.
23. It's a group of similar organisms that can mate with each other and produce offspring that can also mate and reproduce
24. It's the process of grouping things based on their similarities.
25. the study of how living things are classify.
26. It is a group classification that contains similar closely related organisms.
27. It is the kingdom where the organisms can not be classified as animals and their organisms can be Autotrophs and heterotrophs, or unicellular and multicellular:
28. It is the kingdom where the organisms are multicellular, eukaryontes and heterotrophs, some examples are mushrooms, molds and mildew.
29. The kingdom where the organisms are multicellular eukaryontes and autrophs. They provide food for most of heterothophs.
30. All are multicellular eukaryontes and heterothops. They have different adaptations that allow them to locate food, capture it, eat it, and digest it.
31. Facts, figure, and other evidence to get through observations.
32. A dense area in a cell that contains nucleic acids.
33. The mistaken idea that living things can arise from nonliving sources.
34. The person who is trained to use both technological and scientific knowledge to solve practical problems.
35. The structure of the cell that Includes a gel-like fluid in which many different organelles are found.
36. These organelles capture energy from sunlight and use it to produce food for the cell.
37. These small organelles contains chemicals that break down food particles and worn-out cell parts.
38. Most mature plant cell have one large vacuole. This sac within the cytoplasm store food, water, waste and other materials.
39. A large organic molecules made of CHONS, food that are high in protein includes: meat, nuts, breaks, fish eggs etc.
40. The fats oil and waxes are a energy organic compound because contain they even more energy than carbohydrates.
41. Very long organic molecules made of CHOP and nucleic acids that contain the instructions that cells need to carry out the functions of life.
42. Food such a fruits and some vegetables have a high sugar content, your body breaks it down into glucose that your cells can use to produce energy.
43. In this process the result product is the oxygen.
44. In this process the result product is the water and carbon dioxide.
45. During this process the autotrophs use energy from the sun to convert carbon dioxide and water in oxygen and sugar.
46. A colored chemical that absorb Light in plants.
47. A green pigment found in the chloroplants of plants algae and some bacteria.
48. A small opening on a leaf through which oxygen and carbon dioxide can move.
49. Occurs when yeast and some other single-called organisms break down sugars and produce carbon dioxide and small amount of energy.
50. Takes place in you body went your muscle cells uses up the oxygen faster than they can replace it. One of their effects is feel painful sensation in your muscles.
