Explain the concept of natural selection. - It is a process where organisms with advantageous traits leave more offspring than organisms with other traits - causing populations to change over time. (key mechanism of evolution) variation - traits vary from individual to individual heritable traits - A trait that can be passed on genetically from parent to offspring. fitness - the number of offspring an organism leaves over its lifetime compared to other individuals in the population Descri...

Describe the difference between a pure substance and a mixture. - ANSWER-Pure Substance is an element or a compound; a substance with a fixed chemical composition. Mixture is a combination of two or more pure substances. Examples of Pure Substance - ANSWER-Gold - Au Diamond (Carbon) - C Water - H₂0 Methane - CH₄ Examples of Mixtures - ANSWER-Ocean Water Air Rock Alloy Fabric Differentiate between a heterogeneous and homogeneous mixture - ANSWER-Heterogeneous mixture- Components unev...

what happens during a chemical reaction.️️one or more new compounds are formed as a result of the rearrangement of atoms. Explain why the law of conservation of energy is important in chemical reactions.️️states that matter is neither lost nor gained in traditional chemical reactions; it simply changes form. Thus, if we have a certain number of atoms of an element on the left side of an equation, we have to have the same number on the right side. This implies that mass is also conserv...

Define wave. - ANSWER-A disturbance that travels through space and time accompanied by the transfer of energy. It is a vibration, a vibration is a wiggle, and a wiggle that travels is called a wave. Waves carry energy from one place to another. Explain the difference between a transverse wave and a longitudinal wave, and give examples of each. - ANSWER-- Transverse Waves- Waves that move up and down, vibrations perpendicular to the direction the wave travels. Types: Light/electromagnetic, (ra...

Define potential energy - ANSWERSThe energy a system has due to its shape or position. The potential to do work. Example of potential energy - ANSWERSLetting go of a box after picking it up (falls to the ground). Example of electrical potential energy - ANSWERSEnergy between the clouds and ground in a thunderstorm Example of chemical potential energy - ANSWERSfood and gasoline Example of gravitational potential energy - ANSWERSWater tower- Water pumped to the top of a water tower ...

Atomic number correct answersNumber of Protons Transverse Waves correct answers-A ripple in a pond -a wave on a string -light - perpendicular to the direction of propagation of the wave. Longitudinal Waves correct answers-sound waves parallel to the propagation of the wave P Waves correct answerstravel thru solid and liquid Longitudinal waves S Waves correct answersTravel thru solids ONLY transverse waves Fission correct answerssplitting of a large atom into two or more s...
