Answer:
X is the quantity value
Explanation:
To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. Then the standard deviation of X is the quantity. (derived using the properties of expected value). In other words, the standard deviation σ (sigma) is the square root of the variance of X; i.e., it is the square root of the average value of (X − μ)2.
Answer:
The carrying capacity is a measure of how many individuals can a given ecosystem provide for. An individual and its population is dependent on various components of its ecosystem for necessities such as food, habitat, etc. An ecosystem can only successfully support a given population.
Explanation:
An organism that eats decomposed items. For example plant detritus.
1. <span>D. Molten material beneath Earth's crust rises to the surface.
2. </span><span>A. The mid-ocean ridges
(This is asking for what form. The Andes is a mountain range in Peru)
3. </span><span>C. Subduction causes the ocean floor to sink into deep ocean trenches.
(Subduction is when part of the ocean floor sinks under a deep-ocean trench and return the the mantle; this is caused by the movement of tectonic plates)

Answer:
False. The driving for is the partial pressure gradient of O2 (PO2 difference), not the PCO2 gradient.
However, keep in mind that an increase in PCO2 can facilitate the unbinding of oxygen from hemoglobin. This is due to a decrease in pH associated with PCO2 increase. The H+ ions bind to hemoglobin and decrease it's affinity for oxygen, this is called the bohr effect. But the PCO2 is not the main driving force of oxygen unbinding.
