Examine the molecular models of two different substances below. In the
molecule on the left, the electrons are not shared equally. In the molecule on
the right, the electrons are shared equally.
Water molecule, H, O Oxygen molecule, Oz
What is the result of mixing the two substances shown here together?
A. They are not attracted to each other, because one is polar and one
is nonpolar.
O
B. They are attracted to each other, because they are both polar.
O
C. They are not attracted to each other, because water contains an
ionic bond.
D. They are attracted to each other, because they are both nonpolar.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.

i got you i did it ya know what it is just needing to fill this in for a quick task!

these macromolecules could either be amino acids, proteins or nucleic acids. they are responsible for the chemical changes and reactions that affects largely the cell and its composition. take for instance the cytoplasm of the cell where these organelles are settled. these simple organelles are composed of macromolecules which ignites and catalyses different functions that enables cells, in macro-perspective in motion and metabolism. in intestines for example, metabolism happens and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.
