Answer:
1. D (explanation: all the other choices you are able to "observe" on the chart)
2. D (explanation: you are able to see the pig's weight go up on the chart to see that the diet is working)
3. B (explanation: because it shows "number")
4. A (explanation: because it shows the description of what is being observed)
5. C (explanation: you can only assume that the car is being burglarized because the alarm is going off)
6. A (explanation: you are observing "numbers")
7. B (explanation: you are able to see the clear liquid--everything else is not observable because there are no markings to show what each one is describing)
Explanation:
The pulmonary circulation conveys blood that is low in oxygen to the lungs before returning back to the left side of the heart.
<h3>The pulmonary circulation</h3>
The circulatory system is divided into two main parts namely:
- pulmonary circulation and
The pulmonary circulation involves the movement of blood between the lungs and the heart.
Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.
After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.

Nitrogen.
Plants cannot use atmospheric nitrogen directly. Nitrogen from the air must be converted into the different form so plants can absorb it. Thus plants need nitrogen-fixing bacteria to convert atmospheric nitrogen into ammonium, which is available for plants to absorb it.
Explanation: I think the way to do it is to just divide the biomass of the primary carnivores by the herbivores since they are the trophic levels right next to each other. Therefore, the efficiency of energy transfer is (2360/25900)*100%=9.112%. Hope that helped!
Answer:
The freshwater biome is defined as the biome that comprises the water bodies such as lake, pond, rivers and wetlands and where the concentration of salt is almost less than 1%. It occupies near about 20-25% of the total earth's surface.
Generally, the characteristics of the photic zone of a freshwater biome include-
- It forms the upper layer of the freshwater body, ranging from the surface of the water up to a certain depth.
- It is the layer where the sunlight can easily penetrate.
- The photosynthesis process is driven out extensively by the aquatic plants existing in this layer.
- The primary producers are present in this zone that provides the food to almost all the freshwater organisms.
- In this zone, the rate of respiration is equal to the rate of photosynthesis.
