Answer:
The potential energy is 50 joules, 75 joules and 100 joules
Explanation:
Potential energy is the energy stored in an object by virtue of its position relative to others objects. For example a heavy ball placed at an elevated position.
The potential energy is given as:
Where is the potential energy of the object, m is the mass of the object, h is the height in which the object is placed and g is the acceleration due to gravity.
For 1.0 meters:
m = 5.0 kg g = 10 m/s² h = 1 meters
The potential energy is 50 joules
For 1.5 meters:
m = 5.0 kg g = 10 m/s² h = 1.5 meters
The potential energy is 75 joules
For 2.0 meters:
m = 5.0 kg g = 10 m/s² h = 2 meters
The potential energy is 100 joules

Cellular respiration releases energy by breaking down glucose in a process that produces ATP. This ATP is used by cells for many functions.
Explanation:
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, the Krebs cycle, and electron transport chain. In these stages, glucose and oxygen are converted into water, carbon dioxide, and energy.
The energy released during this process is used to synthesize Adenosine triphosphate (ATP), which is used by cells for various functions. So, the significant output of cellular respiration is ATP, the central energy currency of cells.

b. hydrogen bonds within molecules are broken.
c. hydrogen bonds are broken and proteins are permanently denatured.
d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Answers
Answer:
The correct answer is option d, that is, hydrogen bonds are broken, proteins are denatured, and membranes become too fluid.
Explanation:
The maximum growth temperature refers to the highest temperature at which growth can take place. Let us take an example of bacteria, it is found that each bacterial species possess a requirement of specific growth temperature, which is mainly determined by the requirement of the temperature of its enzymes. Each of the organism exhibits an optimum growth temperature, a minimum growth temperature, and a maximum growth temperature.
When for an organism, the temperature goes more than its maximum growth than it results in the dissociation of the hydrogen bonds, denaturation of the proteins, and even the membranes become too fluid. This can even result in the death of the species. However, there are some of the organisms, which can thrive high temperatures known as thermoduric organisms, but they fail to grow effectively at such temperatures.
Final answer:
Exceeding the maximum growth temperature of an organism can lead to the breaking of hydrogen bonds, denaturation of proteins and the over-fluidization of cell membranes.
Explanation:
At temperatures higher than the maximum growth temperature for an organism, d. hydrogen bonds are broken, proteins are denatured, and membranes become too fluid. When the temperature exceeds the maximum threshold for an organism, this exerts stress on the cell causing various biological consequences. For instance, hydrogen bonds within molecules can get disrupted, which can lead to protein denaturation. This means that the proteins lose their functional 3-dimensional shape, a process that can sometimes be irreversible. Moreover, excessive heat can increase the fluidity of cellular membranes to an extent such that they cannot function properly anymore, making the cell unviable.
