A study investigating the effects of light exposure on the growth of algae exposed three groups of algae to different light intensities: low, medium, and high. Over four weeks, the growth of the algae was measured in terms of biomass. The medium-light group showed a 30% increase in biomass, the low-light group showed a 10% increase, and the high-light group showed a 12% increase. Which of the following conclusions is best supported by the results of the study?
A bag made of a semipermeable membrane is permeable to water but not to sugar. The bag is filled with a sugar solution and then placed in pure water. Which of the following observations is expected after a few hours?
The system of interconnected tubes involved in protein production is called

For which of the following reasons does a chloride ion have a negative charge?
Mammalian catalase breaks down hydrogen peroxide into water and oxygen. One milliliter (mL) of catalase is added to a beaker containing 200 mL of hydrogen peroxide. Which of the following scenarios would cause an increase in the rate of this reaction?
Two isotopes of carbon are found: one with an atomic mass of 12 and the other with an atomic mass of 14. Which of the following best describes how these isotopes differ?

Everyday life can be filled with a long list of things that need to be done. Without the necessary skills to meet these demands, it is easy to lose track of deadlines, forget appointments, or misplace important information. By consistently implementing the skills of effective time management and organization, even the most hectic of schedules can become more manageable. The most important aspect of practicing effective time management is learning to create a schedule that provides the time you need to complete necessary tasks. An effective way to do this is to determine whether you have time to add a new task to your schedule. Digital calendars, task management applications, and paper agendas are all widely available tools to manage time and keep track of obligations. By making a habit of recording tasks and events as soon as you receive them, you will maintain a constant record of the time you have available. By effectively managing your time through diligent scheduling, you will always know what needs to be done and when you have time to do it. Maintaining an organized environment is an important part of finishing tasks quickly and effectively. One way to do this is by creating designated locations for different types of information. Whether the information is in the form of physical file folders, books, or digital materials, organization will reduce the time you spend searching for the resources and information you need. Only with consistent practice do the skills of time management and organization become effective tools for managing your everyday schedule. When practiced on a regular basis, these skills provide you with more control as well as a more orderly approach to whatever kind of schedule you might have. Which of the following proposed titles best summarizes the topic of the passage?
Chimney Swifts are small, slender birds that have become a symbol of summer for many. They usually appear during the warm summer months before making their way to more tropical sites for the winter. They are recognized by spectacular, chirping flocks moving through the sky in synchrony; chimney swifts can be seen most vividly at colonies of hundreds or even thousands of individuals, forming tornado-like funnels as they descend into a chimney. Unfortunately, the size of the colonies we see today is misleading. Though the numbers may seem remarkable, chimney swift populations have been declining sharply since the 1970s, due primarily to habitat loss. Unlike most birds, chimney swifts cannot perch or stand upright, so they require long, hollow spaces that provide safe roosting and nesting sites. Historically, chimney swifts preferred hollow trees; however, as humans expanded into their territory and replaced forests with towns, the species was forced to adapt by using other structures, such as masonry chimneys. In the US, the large-scale shift to alternate heat sources, the capping of chimneys, and the use of prefabricated chimneys have drastically limited the birds' ability to find nesting sites during migration. Newer, prefabricated chimneys are often lined with metal flues that make it impossible for the birds' claws to grip the surface. In addition, logging and deforestation have made finding suitable overwintering habitat more challenging than ever. In an effort to sustain the remaining population, conservation groups have designed supplemental housing structures called "chimney towers." These towers are designed specifically to provide roosting sites for chimney swifts, which now rely almost entirely on man-made structures like these to survive. However, because this species is remarkably adaptive, minimal conservation efforts, like keeping traditional masonry chimneys uncapped during the summer months, can improve their chances of survival. Which of the following can be inferred from the information in the passage?
