What are the negative effects of standardized testing? Standardized test scores are often tied to important outcomes, such as graduation and school funding. Such high-stakes testing can place undue stress on students and affect their performance. Standardized tests fail to account for students who learn and demonstrate academic proficiency in different ways. What percentage of […]

What does infectivity mean?
What does infectivity mean? : the ability to produce or transmit infection : the quality or state of being infective The onset of cough on the second day of illness in this patient, followed by clinical evidence of pneumonia four days later, raised the question of his infectivity during the four days before hospitalization.— What […]
Where is urine not modified?
Where is urine not modified? The kidneys are the only means for eliminating the wastes that are the end products of protein metabolism. They do not themselves modify the waste products that they excrete, but transfer them to the urine in the form in which they are produced in other parts of the body. Do […]
How reflected light can be reflected again?
How reflected light can be reflected again? Reflected Light can be Reflected Again When two mirrors are placed opposite to each other, the first mirror reflects light that falls on its surface. The periscope makes use of this concept by using two plane mirrors. Periscopes are used in submarines, tanks and also by soldiers in […]

How can you increase the solubility of a solution?
How can you increase the solubility of a solution? For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions. How do you recover solutes […]
