You feed a canned dog food that is 75% moisture. When analyzed, it contained 30% crude protein and 1.20% calcium on a dry matter
SVETLANKA909090 [29]
To solve the problem, let us note that the calcium percentage no longer considers the moisture content of the canned dog food. Taking the 75% of the sample 681 grams results in a moisture content of 510.75. This is "removed" from consideration and we're left with 170.25 grams which we multiply with the given (dry basis) percentage of calcium to get 2.043 grams of Calcium.

Hi there!

A prezygotic isolating mechanism is a mechanism that causes something to happen, not allowing the organisms to breed before fertilization. I'll explain each one for you.

A - That is postzygotic because the organisms were not stopped before fertilization. The result is a sterile organism.
B - Again, that is postzygotic because the organism was produced. 
C - This is prezygotic! The sperm dying shows that something is in action to prevent fertilization, meaning that it cannot happen.
D - Fertilization was successful, so it is postzygotic.

ANSWER:
C - the sperm dies when it reaches the female tract

If you need help with any more problems, feel free to message me and I'd be more than happy to help you work through them and provide explanations.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
