Answer:
Krill
Explanation:
All animals in the Antarctic depend on krill, very small crustaceans, for their survival.
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.

<u>Answer:</u>
<em>Enzyme activity decrease at these temperatures.
</em>
<u>Explanation:</u>
Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH.
</em>
The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.
<em>At a temperature above 38°c and below 0°c enzyme activity decreases.
</em>

oxygen, let me know if this helps
Answer:
enzymes don't affect the free energy of the reactants or products
Explanation:
That is, they don't change whether a reaction is energy-releasing or energy-absorbing overall. That's because enzymes don't affect the free energy of the reactants or products. Instead, enzymes lower the energy of the transition state, an unstable state that products must pass through in order to become reactants.
