Q: The pull of gravity is expressed as a force of what? Read this paragraph and choose the correct option from the provided answers: One force acting on youand all the other objects on Earthis gravity. Look at the physics book in the Figure below . Gravity pulls the book downward with a force of 20 Newtons. Why doesn't the book fall to the ground? The table pushes upward on the book with the same amount of force. The combined force, or net force , acting on the book is 0 Newtons. That's because upward and downward forces are balanced, so they cancel out. You can learn more about net force at this URL:. Choices: - joule - pascal - volt - newtons A:
newtons

Q: What is a bread mold and research organism that also grows in the wild on burned vegetation Read this paragraph and choose the correct option from the provided answers: Choices: - penicillin - nemophora - whey - neurospora A:
neurospora

Q: Q: What do many fungi secrete that break down complex molecules to smaller molecules that can be absorbed? Read this paragraph and choose the correct option from the provided answers: Choices: - hormones - water vapor - carbohydrates - enzymes A:
A: enzymes

Question: Q: Survivorship curves show the distribution of individuals in a population according to what metric? Read this paragraph and choose the correct option from the provided answers: Figure 19.4 Survivorship curves show the distribution of individuals in a population according to age. Humans and most mammals have a Type I survivorship curve, because death primarily occurs in the older years. Birds have a Type II survivorship curve, as death at any age is equally probable. Trees have a Type III survivorship curve because very few survive the younger years, but after a certain age, individuals are much more likely to survive. Choices: - weight - height - birth rate - age A:
Answer: age

Q: What are the ice crystals that form on the ground called? Read this paragraph and choose the correct option from the provided answers: Deposition as a change of state often occurs in nature. For example, when warm moist air comes into contact with very cold surfacessuch as the ground or objects on the groundice crystals are deposited on them. These ice crystals are commonly called frost. Look at the dead leaf and blades of grass in the Figure below . They are covered with frost. If you look closely, you can see the individual crystals of ice. You can watch a demonstration of frost forming on the side of a very cold can at the URL below. (Click on the mulitmedia choice "Ice on a Can. "). The ice in the can has been cooled to a very low temperature by adding salt to it. If you want to do the demonstration yourself, follow the procedure at the URL. http://www. middleschoolchemistry. com/lessonplans/chapter2/lesson4. Choices: - snow - granules - sleet - frost A:
**Answer**
frost

Q: What occurs when light bends as it passes from one type of matter to another? Read this paragraph and choose the correct option from the provided answers: Light may be refracted by matter. The light is bent when it passes from one type of matter to another. Refraction of light is similar to refraction of sound waves. You can also read more about refraction of light in the lesson "Optics. ". Choices: - vibration - reflection - resonance - refraction A:
refraction
