Answer:
Independent variable: Amount of sunlight
Dependent variable: Plant height
Explanation:
The independent variable is the one that a scientist intenionally changes in an experiment, while the dependent variable is the one that changes in response to the independent variable. In this case, the amount of sunlight given to each plant is intentionally varied so it is the independent variable, while the height of each plant depends on the amount of sunlight given so it is the dependent variable.

The two events in earth's history with great impacts on carbon cycle is the burning of fossils fuels and the change in land use and land cover. burning of fossils fuels in homes and industries extracts the carbon from the fossil fuel and emit it as carbon dioxide in the atmosphere. change in land use such as deforestation also change the amount of carbon in circulation.
<span>The answer to this question would be: Heart rate 88

Respiratory distress in asthma patient can be dangerous. It won't only affect the respiratory system but also cardiovascular system. In asthma, the expiration phase is longer and harder because of the obstruction. This will cause lower amount of oxygen gain and lower amount of carbon dioxide dumped. The right ventricle also needs extra force since the lungs pressure is increased. The heart rate should be increased in this case to compensate the lower oxygen level.
Heart rate 88 is normal, not increased. This is a sign that the heart is already tired and might go arrest.
In other words, the term homeostasis is being used to describe the body’s maintenance during resting conditions whereas the term steady state refers to the body’s maintenance<span> during exercise; exercise is a stressor which disrupts homeostasis, also called homeostatic disturbance (e.g. an increase in temperature).
</span>Homeostasis is the maintenance of a constant internal environment (the immediate surroundings of cells) in response to changes in:
the changing conditions of the external environment.
the changing conditions of the internal environment.
Homeostasis is a self adjusting mechanism involving feedback where the response to a stimulus alters the internal conditions and may itself become a new stimulus.
<span> Homeostasis works to maintain the organism's internal environment within tolerance limits - the narrow range of conditions where cellular processes are able to function at a level consistent with the continuation of life. </span>
