A molecule is composed of atoms. True or False? - correct answers True What is the difference between a theory and a hypothesis? - correct answers A theory is supported by all existing evidence and have never been shown to be false. A hypothesis is a proposed explanation for a set of observations that requires further evidence to be supported or discarded. All living things evolve. True or False? - correct answers True A population is part of a community. True or False? - correct answers True The theory of evolution still lacks evidence and therefore it is not accepted by science. True or False? - correct answers False Every organelle is made of many cells. True or False? - correct answers False What are properties of all living things? - correct answers -They have complex but well-ordered structures. -Reproduction -Are made of cells -They process matter and energy. The biosphere includes all the ecosystems that exist on Earth. True or False? - correct answers True Choose statements that are true about viruses: - correct answers -Viruses can evolve -Viruses can reproduce but not on their own. Which living thing does not respond to the surrounding environment? - correct answers None: ALL living things respond to their surrounding environment. A molecule is part of an atom. True or False? - correct answers False A community is part of a population. True or False? - correct answers False Increasing the temperature of water by 1 degree requires less energy than would be needed to do the same with other liquids. This property allows the water in our body to change quickly in response to changes in the surrounding environment. True or False? - correct answers False A chemical bond in which _______________ are lost/gained is called a _________ bond. But if these charged particles are shared, is called a _____________ bond. - correct answers Electrons, ionic, covalent One liter of liquid water is heavier than the same volume of ice. True or False? - correct answers True If the concentration of Hydrogen ions increases in the solution, the pH becomes more alkaline. True or False? - correct answers False __________ of water are made of ______________of hydrogen and oxygen. - correct answers Molecules, atoms A molecule is composed of atoms. True or False? - correct answers True A pH of 4 is more acidic than a pH of 10. True or False? - correct answers True The properties of water that make life possible are largely due to _________ - correct answers hydrogen bonds The most abundant chemical elements in living organisms are: - correct answers Oxygen, carbon, hydrogen, and nitrogen. A molecule is part of an atom. True or False? - correct answers False In a non-polar bond some atoms are slightly charged. True or False? - correct answers False Excluding water, most of the molecules in living organisms are based on which element? - correct answers Carbon The organelle responsible for cellular respiration is called: - correct answers Mitochondria Both prokaryotic and eukaryotic cells use ribosomes to build proteins. True or False? - correct answers False What are examples of active transport? - correct answers Moving a substance against its concentration gradient. The cytoskeleton is made of: - correct answers Proteins Prokaryotic cells do not have organelles. True or False? - correct answers True After the Translation, some Proteins are transported and finished in the organelle known as: - correct answers Golgi Apparatus Translation is the process in which a protein is synthesized by ribosomes, using information provided by an RNA molecule. True or False? - correct answers True The Rough Endoplasmic Reticulum is associated with the production of: - correct answers Proteins The organelle responsible for photosynthesis is called: - correct answers Chloroplasts Molecules that have affinity with water, are attracted to water, are somewhat "water-loving," and therefore mix with water are called: - correct answers Hydrophilic Every organelle is made of many cells. True or False? - correct answers False The Transcription occurs in the nucleus. True or False? - correct answers True The Nucleolus is associated with the production of: - correct answers Ribosomal RNA Mitochondria contain DNA. True or False? - correct answers True Phospholipids are molecules that have hydrophobic ________________ and _________ _____________ - correct answers Tails, hydrophilic, heads The diffusion of water is called: - correct answers Osmosis The Translation occurs in the nucleus. True or False? - correct answers False Translation is the process in which the information to synthesize a protein is translated from the DNA into RNA. True or False? - correct answers False Transcription of DNA into RNA occurs inside which organelle? - correct answers Nucleus What organelles/structures occur in plant cells and are absent in animal cells? - correct answers -Central Vacuole -Chloroplasts -Cell wall The outputs of light reactions are: - correct answers ATP and NADH
