Answer:
The correct answer is -
Numerator = 6
Denominator = 73
Explanation:
In F static test or table there are two sets of degrees of freedom: one for the numerator and one for the denominator. The degrees of freedom are equal to the number of observations minus one. Thus, if the sample size were 7 then the degree of freedom would be 7 minus 1
Numerator df = 7 - 1 = 6
Thus, the numerato would be - 6.
Denominator is calculated by subtracting the observation or variables from the total number of sample size.
Denominator df = 80- 7 = 73
Answer:
I think the answer is B. I think energy decreases as it moves up tropic levels when it is lost as the organisms from one level consume the organisms in the other.
Explanation:
It can't be A because animals do travel from one ecosystem to another. It's migration. It's not C because air can be used by organisms as once as the air moves out of their ecosystem because air is everywhere and the organisms need air to breathe and to live. D is definitely incorrect because matter can't be created or destroyed. Remember that an ecosystem is the organisms physical environment. I hope this answers your question.

Answer:
lungs and kidneys
Explanation:
The median plane divides the body into two halves through a mid line.
The transverse plain is also known as the axial plane and it divided the body into the upper part and a lower part.
The frontal plane is also known as the coronal plane. It divided the body into the dorsal and ventral sections. The dorsal and ventral sections are the front and back sections ( belly and back).
Lungs and kidneys are the only parts which cannot be seen through all the three plains.
This produces medicines that can possibly save the lives of cancer infected patients who otherwise could die.
