10 POINTS
Brrunno [24]

Answer:

450 kilocalories.

Explanation:

Since only 1/10th of the energy that an organism consumes is passed onto the next level of the pyramid, that would mean only 500/10 = 50 kilocalories are passed on, and the remaining 500 - 50 = 450 kilocalories are used up.

Hope this helped!

In human pedigree if a symbol is fully filled what does it represent?
Ronch [10]

Answer:

See the answer below

Explanation:

<em>If a symbol is fully filled in a human pedigree, it means that the individual represented by the symbol is affected by the trait whose inheritance is being illustrated by the pedigree.</em>

The human pedigree generally represents a symbolic illustration of how a particular trait is inherited across generations in a particular family. It shows the relationship between the members of a family and how the trait is passed down each generation either in a silent or expressive form.

Individuals within a human pedigree are represented with symbols and <u>those affected by the trait in question are completely shaded</u>. <u>Those carrying the trait in silent form are half-shaded while those that do not have traces of the trait at all are left completely unshaded.</u>
