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:
Explanation:
An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.
<span>The question is asking us Which organism is an example of a producer? A producer in an ecosystem is an organism that does not eat other organisms (such as moth and cheetah - they eat other plants or animals) but instead, one that produces its own food from the solar energy in the process of photosynthesis - so the correct answer is the only plant, rose</span>
The answer is B. fight disease
Answer:
Pulmonary artery
Explanation:
The pulmonary artery delivers oxygen poor blood to the lungs that comes from the right ventricle of the heart. The pulmonary artery is also the only artery in the body that carries unoxugenated blood. When the blood goes to the lungs, it picks up oxygen and drops off carbon dioxide to be expelled from the body. The pulmonary vein then takes the oxygen-rich blood and brings it back to the heart.
