Based on the information, which plant leaf symptom could have resulted from more than one type of nutrient deficiency?
As plants grow, they absorb nutrients from the soil. Plant leaves can be carefully observed to determine the relative healthiness of the plant and whether it is suffering from a nutrient deficiency. The chart below shows the most common nutrient deficiencies and their effects on plant leaves. Sometimes an observed...
Which example would be considered science rather than technology?
Science is a systemized body of knowledge based on observation and experimentation. Technology involves applied science and the practical applications of scientific knowledge. The making of lenses for eyeglasses is a technology that is based on the scientific principles of optics explaining how light rays are bent by finely ground...
Based on the information, what can be concluded about enzymes in the digestive system?

Based on the information, which statement indicates where and why Allan would find the most fish?
Temperature affects how well gases and solids dissolve to form solutions. Gas solubility increases with decreasing temperature. Cold water can hold more oxygen than warm water. Fish require dissolved oxygen in the water for respiration. During the hot summer, Allan goes fishing at a nearby lake. Based on the information,...
When this type of event occurs, which statement describes the most important factor about a scientific finding’s acceptance by the scientific community?
A scientist published his work in a scientific journal, and it generated much excitement in the scientific community. However, when other scientists across the world did the same experiment to try and repeat the results, it proved to be impossible. When this type of event occurs, which statement describes the...

In the gear arrangement shown at the left, turning gear A will turn gear B in the direction marked with arrows. Which of the following will cause gear B to turn more rapidly?A . turning gear A more slowlyB . putting a gear of smaller diameter at BC . using...
Based on this information, which statement best summarizes the blood condition that might result when an individual has a respiratory condition that causes the blood to contain too much CO2?
The pH of a liquid is a measure of its acidity or its alkalinity. Even small changes in pH of human blood can cause very serious health problems. Carbon dioxide (CO2), is one of the dissolved gases present in healthy blood. CO2 normally mixes with the water in blood to...
Which of the following actions explains why this effect of catalase is typical of an enzyme?
A clear container of hydrogen peroxide breaks down to form water and oxygen in approximately one month. When an enzyme known as catalase is added to hydrogen peroxide, water and oxygen are formed almost immediately. Which of the following actions explains why this effect of catalase is typical of an...
When using a kerosene stove, which action provides the best protection against these harmful gases?
