What do energy pyramids show? An energy pyramid shows the distribution of energy among trophic levels. Producers use energy from sunlight to make food. In other words, an energy pyramid shows how much energy is available at each trophic level. Energy is lost at each trophic level of a food chain. How does energy flow […]

How do you classify plant and animal cells and tissues?
How do you classify plant and animal cells and tissues? The Theory A group of cells having common origin, similar structure and performing a definite function is called a tissue. Plant tissues can be grouped into two basic types: meristematic and permanent tissues. Animal tissues can be grouped into four basic types: epithelial, muscular, connective […]
Does mass affect orbit speed?
Does mass affect orbit speed? 1 Answer. Steve J. Assuming we are talking about the mass of the satellite (and not the mass of the body being orbited), mass does not affect the orbital speed. Can you still see Sputnik? This metal arming key is the last remaining piece of the Sputnik 1 satellite. It […]
How does culture influence behavior?
How does culture influence behavior? If culture fosters a more extroverted personality style, we can expect more need for social interaction. Additionally, Individualistic cultures foster more assertive and outspoken behavior. When the general population encourages these gregarious behaviors, more ideas are exchanged and self-esteem increases. How does culture influence cognitive development? Within the context of […]
How do you calculate temperature change over time?
How do you calculate temperature change over time? Subtract the final and initial temperature to get the change in temperature (ΔT). Multiply the change in temperature with the mass of the sample. Divide the heat supplied/energy with the product. The formula is C = Q / (ΔT ⨉ m) . What is mean monthly temperature? […]
Why does hydrogen peroxide decompose slowly?
Why does hydrogen peroxide decompose slowly? Hydrogen peroxide has a finite shelf-life because, over time, it naturally decomposes into water and oxygen gas. Although this will take a while, UV rays from sunlight as well as warm conditions can actually catalyse the decomposition reaction. What happens to hydrogen peroxide when exposed to light? When exposed […]
How many carbon monoxide detectors should a house have?
How many carbon monoxide detectors should a house have? As a minimum, each home should have one CO detector on each floor, one in or just outside each sleeping area, and one in the basement. In homes where multiple bedrooms adjoin a common hallway, a single detector in the hallway can provide protection for all […]

Is the force of attraction between two objects?
Is the force of attraction between two objects? Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the […]
