The Major function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli, the layers of the cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other, the barrier between air and blood averages about 1 micron in thickness. Oxygen diffuses quickly through the air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.
She should investigate how temperature affects the rate of oxygen production.
<h3>Photosynthesis</h3>
During photosynthesis, green plants make use of inorganic products in the form of water and carbon dioxide to synthesize carbohydrates. The reaction only happens in the presence of solar radiation and oxygen is evolved as a by-product.
The process involves a series of chemical reactions. However, the summary of the whole reactions is represented by the following equation:
carbon dioxide + water ----> glucose + oxygen
Thus, if Emily is to find out how temperature affects photosynthesis. She will need to use a plant as a case study. One factor that can easily be used to measure the rate of photosynthesis is oxygen production by plants.
In other words, Emily will have to set up an experiment where a plant species will be subjected to the same environmental conditions, except temperature. Then, a suitable method will be used to measure the amount of oxygen produced. Any difference in the volume of oxygen produced can then be attributed to the effects of temperature.

Because astrologers don't use tools , don't observe the planet.
Hello. You forgot the results of Courtney's observations. The observations are:
"Tendril # Week 1 Week 3 Week 6
1 1.2 cm 5.9 in 1.2 ft
2 2.0 cm 4.8 in 0.98 ft
3 0.8 cm 3.2 in 0.55 ft
4 0.2 cm 1.6 in 0.35 ft
5 1.5 cm 4.3 in 1.01 ft"
Answer:
Curtney's data show inconsistent units of measure.
Explanation:
Measurement units are ways of representing great physics such as speed, size, time, quantity, weight, among others. These units serve to quantify the matter and allow observations to be made.
It is important to note that the same units of measurement must be evaluated in the same experiment. For example, if we want to evaluate how much a plant can grow in 3 weeks, we have to evaluate the same unit of measure each week. If in the first week we evaluate the growth in centimeters, we have to evaluate the growth in the next weeks also in centimeters.
Courtney did not do this, and assessed the growth of the plants each week with different units of measure, which left her data inconsistent.
Answer:
B. sending neurotransmitters to endocrine target cells
Explanation:
Your endocrine system works closely with your brain and central nervous system to control the creation of specific hormones and enzymes.
