The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.
The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.
When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.
When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling
Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.

Many people feel the use of stem cells has great potential for scientific and medical progress, while others have been opposed to it. Today there is a great deal of debate about stem cell research using pluripotent stem cells from an embryo. Provide an argument for people in favor of continuing stem cell research. Include in your answer the uses of stem cell research and a suggestion for obtaining a source of stem cells without risk to life. (2 points)
Answer:
Stem cells can benefit humanity in a variety of ways, one, being the ability to develop into another cell. This is remarkable for people who have diseases and or health issues, requiring them to replace cells that they lack. Not only that, but they help treat diseases like stroke, heart disease and diabetes.

If a plant with chlorosis is unable to perform photosynthesis, what products (include
BOTH) are not being made?
Answer:
Glucose and oxygen
Explanation:
Photosynthesis is the process by which the cells of green plants synthesize their own food in the presence of sunlight. Although photosynthesis consists of various steps, it generally combines carbon dioxide (CO2) and water (H2O) to produce glucose (sugar) and oxygen gas (O2). The equation is as follows:
6CO2 (g) + 6H20 (l) → C6H12O6 (aq) + 6O2(g)
In a plant that possess chlorosis (a condition characterized by yellowing of leaves due to lack of chlorophyll), photosynthesis will not occur. This ultimately means that the photosynthetic products such as GLUCOSE AND OXYGEN WILL NOT BE MADE.
Describe the events that occur during the cell cycle. Include what happens in each of the following stages: interphase, mitosis, cytokinesis.
Answer:
Cell cycle or cell division refers to the series of events that take place in a cell leading to its maturity and subsequent division. These events include duplication of its genome and synthesis of the cell organelles followed by division of the cytoplasm.
interphase-During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
mitosis-In cell biology, mitosis is a part of the cell cycle, in which, replicated chromosomes are separated into two new nuclei. Cell division gives rise to genetically identical cells in which the total number of chromosomes is maintained.
Cytokinesis-Cytokinesis is the division of the cytoplasm in eukaryotic cells that produces distinct daughter cells. Cytokinesis occurs at the end of the cell cycle following mitosis or meiosis. In animal cell division, cytokinesis occurs when a contractile ring of microfilaments forms a cleavage furrow that pinches the cell membrane in half.

Use Demetri's results to explain how temperature affects enzymes
Answer:
As with many chemical reactions, the rate of an enzyme-catalysed reaction increases as the temperature increases. However, at high temperatures the rate decreases again because the enzyme becomes denatured and can no longer function. ... As the temperature increases so does the rate of enzyme activity.

Which of the following best explains why aerobic respiration is more energy efficient than anaerobic respiration?
With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
Since photosynthesis primarily takes place in the leaves, it is essential that glucose can be transported out of the
cell to other parts of the plant. The selectively permeable plasma membrane only allows certain molecules to
cross freely through the phospholipid bilayer.
Is glucose a molecule that is allowed to cross the selectively permeable membrane freely?
Answer: A
No, glucose passes through a channel protein with the concentration gradient via facilitated diffusion.

"What would railroads do if every state had different requirements for smokestacks or track width?"
Answer:
The train will move on the roads.
Explanation:
If every state had different requirements for smokestacks or track width, the trains should be run on the roads because if there is different requirement for track width, it is impossible to run same type of train on these tracks. One another act will be done and that was to make different types of trains for each state so that they can move on the tracks. But it is impossible for having different track width, it must be of same width.
