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.
The density and variety of receptors vary in different regions. For example, in hairy skin the peritrichial endings are most common, but Merkel's discs and free nerve endings are also present. In glabrous (hairless) skin, free nerve endings are present, as are Merkel's discs and Meissner's corpuscles.
The difference between animal and plant cells is that they contain different organelles, among these are the chloroplasts that plant cells contain and animal cells do not.
<h3>What are the differences between animal and plant cells?</h3>
Each of these cells will have their own requirements, which is why they will have different types of organelles to be able to meet these requirements. Among the differences will be that plant cells will have chloroplasts to be able to generate their own food since they cannot obtain it by other means, so they will manufacture sugar through sunlight.
In plant cells it will have a cell wall that will be surrounded by a cell membrane. While animal cells will not have this cell wall.
Therefore, we can confirm that plant cells and animal cells will have differences in their content, function and organelles.
