The contractions of the heart is what creates out blood to pulse through out body and is the basis of our blood pressure; which means this statement is TRUE.
The systolic number (top) of the blood pressure is our heart physically pushing the blood out of the heart and to the rest of the body.
The diastolic number (bottom) of the blood pressure our heart at rest when it has just finished with one pump.
Answer:
The correct answer is C and Engelmann conducted this experiment to prove relationship between algae and the rate of photosynthesis.
Explanation: First we must talk about 3 facts:
1) Prism scatters the white light into different wavelengths.
2) Photosynthesis, 6 carbon dioxide and 6 water molecules are consumed and 6 oxygen and 1 sugar molecule is synthesized using light energy.
6CO2 + 6H2O → C6H12O6 + 6O2
3) Aerobic bacteria breaks down sugar while using oxygen and produces water and carbon dioxide in simplified terms.
So with this experimental setup a researcher can understand the rate of the photosynthesis by increased accumulation of aerobic bacteria near algae in certain wavelengths since they uses oxygen and tend to move close to the oxygen source (<u>see figure</u>). In this experiment there are no ways to measure heat (B), there is no known relation between wavelength of light and aerobic respiration since it can happen even in the dark (A) and finally there are no ways to measure carbon dioxide (D).
Answer:
Grass
Explanation:
Grass is the producer in the given food chain.
Note : -
Grasses are green plants which synthesize food ( carbohydrate ) in presence of sun light in the process of photosynthesis. That's why grass is called producers.
