Answer:
box 4, because it has more atoms in the same amount of space
Answer:
This question lacks options, options are:
a) The partial pressure of oxygen
b) Acidity
c) The partial pressure of carbon dioxide
d) Temperature
e) BPG
The correct answer is a. The most important factor that determines the percent of oxygen saturation of hemoglobin is <u>The partial pressure of oxygen
</u>.
Explanation:
Hemoglobin is an oxygen transport protein. Partial Oxygen Pressure (PaO2), measures the pressure of dissolved oxygen in the blood, that is, it shows how well oxygen passes from the lungs into the bloodstream. A high partial pressure of oxygen in the blood produces an almost complete saturation of hemoglobin, which indicates the maximum amount of oxygen that combines, but when PaO2 is reduced, so is hemoglobin saturation, when saturation is below 90% hypoxemia occurs, that is, the level below normal blood oxygen levels.
Answer: Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function.
Answer:
Competition will occur between organisms in an ecosystem when their niches overlap, they both try to use the same resource and the resource is in short supply. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.
<span>A. 5/8
B. 2/3
C. 10/12
D. 3/4
We need to simplify the fraction. Whatever number we use to divide the numerator, should also be the number used to divide the denominator.
18 </span>÷ 2 = 9
24 ÷ 2 = 12
9 ÷ 3 = 3
12 ÷ 3 = 4
18 / 24 is equal to 9/12
18 / 24 is equal to 3/4 CHOICE D.
3/4 IS THE SIMPLEST FORM OF THE FRACTION 18/24
