People with O+ blood cannot donate their blood to negative blood types, while people with O- blood can donate to any blood type. This makes them the "universal donor." However, they can only receive O- blood.

The difference between the O+ blood type and the O- blood type is that even though they both belong to the blood group O, the O+ type has rhesus factor (an antigen which may be present on the blood) on the red blood cells while O- does not have Rhesus Factor on the red blood cells.

O- can only get blood from O- donors because the O- red blood cell would have no antigen on it (neither the A, B or Rhesus Factor Antigen).  As a result if they obtain blood from any other blood type then their white blood cells would attack the red blood cells due to the the presence of foreign bodies in the form of the antigen on that blood.

In a particular woodland community, two species of rodents coexist: mice and chipmunks. Both species compete for the same kinds
scZoUnD [109]

Answer:

First, we take the owl out, the total number of mouse increases at a higher rate and the chipmunks are also decreasing in numbers. In an ideal ecosystem, both mice (lets call it "a") and chipmunks (lets call it "b") should increase since the restraining factor has been removed. But that is the opposite of what we should see. In that case, we will take the owl to be the "limiting factor" for the rodents.

Am

The rodents will have free movement and exercise their fitness over the area, competition sets in between the two species. So we see, a flourishes while b dies out. This can be viewed most predictably that a has an overall greater fitness and would easily get resources and strive readily, which influences the survival rate for 2.

Hope you got something in any realm of understanding?

Each child born to a particular set of parents has probability 0.25 of having blood type o. if these parents have 5 children, wh
Taya2010 [7]
Use binomial distribution with p=0.25, n=5, x=2
P(X=x)=C(n,x)p^x (1-p)^(n-x)

P(X=2)=C(5,2) 0.25^2 0.75^(5-2)
=10*0.0625*0.421875
=0.26367

So the probability of 2 of 5 children having type-O blood from these parents is 0.26367.
