Living Environment Regents practice (2015 regents questions)

Residents of a town are concerned that a recently built factory could pose health risks. Scientists were asked to investigate the effects of the factory on the health of local residents. The most relevant information they reported was that 

• (4) local medical facilities have recently reported a 15% increase in the number of patients treated for asthma
• (3) residents have occasionally seen smoke coming from the factory 
• (2) there have been reports that other types of factories have been linked with health issues 
• (1) in a survey, residents felt that the air in town looks dirtier now

The diagram below represents a cell and some molecules in its environment. Which molecule would require the use of energy in order to be brought into the cell? 

• 1
• 2
• 3
• 4

A farmer wanted to rid his apple trees of a particular leaf-eating insect. He sprayed his trees with an insecticide that killed 98% of the insects. The survival of 2% of this population of insects is most likely due to 

• (1) genes obtained from another species 
• (2) certain chemicals that stimulated overproduction
•  (3) variations that resulted from sexual reproduction 
• (4) their ability to produce food from the pesticide

Populations of aspen trees in the western United States are being destroyed by an unexplained illness. The altered landscape is affecting the animals that live there. Populations of deer mice are increasing greatly in these areas. Unfortunately, these mice often carry a virus that is deadly to humans. This scenario best illustrates that  

• every population in an ecosystem is linked with other populations
• the stability of this ecosystem is limited by the amount of water available
• humans are the cause of the breakdown of this ecosystem
•  a change in the environment always results in disease

 Which statement is true for all of the organisms in the ecosystem represented in the diagram below? 

• Energy is used by the organisms to obtain and transport materials, and to eliminate wastes
• Energy stored in inorganic molecules is released during cellular respiration in these organisms. 
• Stored energy cannot be used by these organisms as a source of energy for life processes. 
•  They use energy to combine the inorganic molecules carbon dioxide and water into energy-rich organic compounds.

What observation could lead to the conclusion that an object is nonliving?

• It passes on hereditary information only through asexual reproduction
• It carries out synthesis
• It cannot perform metabolic processes
• it is composed of a cell, but does not have tissues

• return nutrients to the ecosystem
• absorb energy from the Sun
• Produce organic nutrients
