I know they help us digest food and make vitamin k, protect us from pathogenic bacteria and fungi. May be more.
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.

Answer:
<em>y = 0.6.x - 3.2</em>
Explanation:
The slope-intercept form:
<em>y = mx + b</em>
m - slope
b - y-intercept
We have
<em>y + 0.6x + 3</em>
<em />
Parallel lines have the same slope. Therefore we have the equation:
<em>y + 0.6x + b</em>
The line passes through the point (-3, -5). Put the coordinates of the point to the equation and solve it for b:
<em>-5 = 0.6(-3) + b</em>
<em>-5 = - 1.8 + b</em>
<em>-3.2 = b</em>
add 1.8 to both sides
Finally we have:
<em>y = 0.6.x - 3.2</em>
