Answer:
8+5 = x - 7
Explanation:
a number is X
sum means addition
difference means subtraction
To solve: You need to isolate x on one side of the equation (one side of the = sign). To do this, add 7 to both sides so you can move it from one side to the other:
8 + 5 = x - 7
+7 +7
As you can see, adding 7 will cancel out the - 7 on the right side, and move it to the left. Now the equation you are left with is
8 + 5 + 7 = x
Finally add the numbers together and you will get your value for x.
8 + 5 + 7 = 20
20 = x
I am not sure if this counts, but maybe seals and whales.
Explanation:
Some general comments about gas exchange and diffusion will be made, followed by a description of how oxygen is carried in the blood. The binding of oxygen to hemoglobin will be discussed, including the oxygen saturation (or dissociation) curve and factors (allosteric effectors) which cause it to shift. Next, a discussion of the effects of carbon monoxide on oxygen binding will be presented. Finally, a description of artificial oxygen carriers will be presented. Most of these topics are covered in standard textbooks [6,10,54,113] and monographs on oxygen transport [112].
<em>A natural disaster. </em>
Explanation:
A natural disaster would most likely have occurred to have the population of squirrels completely diverge from each other in order for them to become two separate species.
If a tornado, flood, earthquake, or another type of a natural disaster were to happen, it may have caused drastic damage to the ecosystem and environment of the squirrels. This would most likely cause the squirrels to split up, or diverge from each other and go to separate places in search of a new home.
Over time, these squirrels will reproduce with their own group. Each new group of squirrels, as they are both in different environments now, will have different adaptations from each other. This will eventually make it so they will never be able to reproduce with each other again if they were to meet, as they are now completely different species of squirrel.
