Answer:
The statement that can best explain why during the warmer parts of the day, fish are found in deeper waters of a lake is that warmth lowers the oxygen concentration near the surface.
Explanation:
Organisms in any aquatic ecosystem require oxygen to perform their functions and survive. But the availability of dissolved oxygen in water, especially at the surface, can be affected by environmental temperature.
- <em>Warm temperature decreases the dissolution of oxygen in the lake surface water, encouraging fish to move to deeper areas.
</em>
- <em>Lower temperatures increase the dissolution and availability of water at the surface, so fish can be found closer to the surface when the weather is cold.
</em>
This behaviour of dissolution / availability of oxygen at the lake surface can be observed with seasonal changes or with temperature changes between day and night.
Answer:
1. warm blooded, 2. breast feed its young
Explanation:
Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. AND hales are other mammals that feed their young milk too, although it takes plenty more to feed them than human babies
Explanation:
<em><u>The desert plants do not open stomata during the night time to absorb carbon dioxide where the temperature is too low during night time to prevent water loss. Additional Information: ... Xerophytes are the plants that perform photosynthesis to absorb carbon dioxide during night time to prevent loss of water.</u></em>
