Answer:
<em>Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?</em>
- From factory emissions to carbon dioxide in atmosphere (<u>C</u>)
- The process occuring can be called as <em>Combustion</em>. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because carbon in organic matter is oxidized to form CO2.
<em>Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.</em>
- from dead organisms to fossils and fossil fuels (E)
- The process explained in the question can be stated as <em>Fossilisation</em>. In this process, dead remains of plants and animals are transformed to fossils under pressure. The organic matter is preserved according to the shape of organism.
<em>Which arrow or arrows represent reactions that demonstrate conservation of mass and energy? Explain your answer.</em>
- from factory emissions to carbon dioxide in atmosphere (C) & from carbon dioxide in atmosphere to photosynthesis (B)
- Two reactions represent the converstion of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure.
Answer: Option C.
C)the tails of plant lipids cannot pack as tightly together as animal ones
Explanation:
The tails of plant lipids cannot pack as tightly together as animal ones because the double bond in plant lipids make the hydrocarbon chains to bend making them no to pack tightly together which cause a reduction in van der Waals interaction between the fatty acids. The length of the double bond also affect the melting point of fatty acids . If the hydrocarbon chain is long, melting point will be high .
I think the best explanation to this is that plants will do everything to get sunlight thats why they move in order to get more. I hope you are satisfied with my answer and feel free to ask for more if you have questions and clarifications
The sign that shows food spoilage is bulging or leaking cans. That is option C.
Food substances can be stored or preserved to prolong the nutritive values and shelf life of the food.
Food spoilage occurs when environmental factors such as:
- Light,
- oxygen,
- heat,
- humidity,
- temperature and
- spoilage bacteria
causes food to become unsuitable for consumption.
For canned products, bulging or leaking cans shows the food content has deteriorated.
This shows some ongoing fermentation by a spoilage bacteria causing the can to bulge and eventually leak out.
Therefore, the sign that shows food spoilage is bulging or leaking cans.
