What is the main difference between conductors and insulators? In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. What are the similarities between conductors […]

Which of the following types of models could be used to represent a cell? A cell may be represented in different models such as an idea model, a physical model and even a computer model. How can or models be classified? MODEL CLASSIFICATIONS. Some models are replicas of the physical properties (relative shape, form, and […]

Is hydrogen a reactant or product? Reactant: is the numbers of each of the elements on the reactants side of the reaction equation. Product: is the number of each element on the product side of the reaction equation….Balancing. Element Number of reactants Number of products Hydrogen 1 2 2 Chlorine 1 2 2 Magnesium 1 […]

What are the advantages of asexual reproduction over asexual reproduction? Advantages Of Sexual Reproduction Over Asexual Reproduction Variations are more successful in sexual mode than in asexual one. The species produced by sexual reproduction survive more than those produced by asexual reproduction. This is because genetic variations help them to adapt to different environments. What […]

What is in the continental crust that makes it float than the oceanic crust? The minerals that make up oceanic and continental crusts have different densities; oceanic crust is generally more dense than continental crust. Both oceanic and continental crusts are generally less dense than the asthenosphere, so most oceanic and continental crusts “float” on […]

What makes ocean breezes blow toward land by day answers com? What makes ocean breeze blow toward land by day? The land absorbs heat and loses it at a rate faster than the ocean. Accordingly, during day land gets hotter than ocean and air above land becomes hotter and of less density. This is the […]

What are the criteria and constraints of the design problem? Explain the terms “criteria” and “constraints.” Criteria are things the design needs to do in order to be successful–its requirements. Constraints are limitations on the design. These may be materials available, the cost of the materials, the amount of time they have to develop the […]

How does a mineral appear to reflect light? Luster is the property of minerals that indicates how much the surface of a mineral reflects light. The luster of a mineral is affected by the brilliance of the light used to observe the mineral surface. Metallic The mineral is opaque and reflects light as a metal […]

How many ions are in aluminum oxide? All samples of aluminum oxide have an atomic ratio of two aluminums for three oxide ions. How many aluminum ions are in a formula unit of aluminum oxide? 2 Are Aluminium cans safe? Over the years, some studies have attempted to draw a negative correlation between overall health […]

How does co2 enhanced greenhouse effect? Burning fossil fuels like coal and oil puts more carbon dioxide into our atmosphere. NASA has observed increases in the amount of carbon dioxide and some other greenhouse gases in our atmosphere. Too much of these greenhouse gases can cause Earth’s atmosphere to trap more and more heat. This […]
