The answer for this will be C an integration of organ systems this is because the endocrine system also works with the nervous system and immune system etc
The pH of seawater is about 8.1, making it alkaline.
The average pH of sea water is about 8.1 but it can also range between the pH value 7.9 to 9.0 as the result of the various activities that happen in the water. At this pH range, HCO3 ions are the major ions that are present, but as the pH of the water increases, the carbonate ions levels also increases, thus, when carbon dioxide dissolves in water it makes the water to become acidic.
Answer:
C is the correct answer.
Explanation:
i attached a photo of the structure of two different nucleic acids. the structure shown on your paper matches up with the DNA model, therefore c. nucleic acid is the correct answer.
Answer: the answer is northeast
Explanation:
Answer:
- E. Does photosynthesis performed by elodea remove CO2 from the water?
- F. Does cellular respiration occur at a higher rate than photosynthesis in the tube with only elodea?
Explanation:
The tubes were placed under a growth light and as the elodea is growing, it would need photosynthesis to provide food. The color changes will therefore allow the students to see the effect photosynthesis has on the CO2 in the water by checking to see if the BTB turns blue which would mean that CO2 was removed by photosynthesis.
The students will also be able to see which process occurs faster in the tube with only elodea because the dominant color would show if cellular respiration occurs faster than photosynthesis or if the case is the reverse. For instance, if respiration is occurring faster, there will be more CO2 which would turn the BTB towards yellow, if photosynthesis is faster the BTB will turn towards blue and if the rates are similar, the BTB will remain green.
