You should use a Punnett Square for this question
The Punnett square predicts the offspring of two parents (two alleles). In this case you have brown eyes (Bb) and blue eyes (bb)
In the four boxes you should have Bb, Bb, bb and bb (50% chance of offspring with blue eyes and 50% chance of offspring with brown eyes).
The genotypes ratio will be 2Bb:2bb
And the phenotypic ratio will be 2 Brown : 2 Blue
The temperature is lowest at the crust. As you get lower into the Earth's surface, the temperature gets hotter.
Answer: A.They contain plants that purify water.
With fossils, scientists can use carbon dating to determine the approximate age of whatever fossil they have.
A non random influence affecting who survives or reproduces
is selective pressure. A selective pressure is considered to be a phenomenon in
which behaviors of the living organisms are being driven to evolution and the
natural selection in which they are also divided in to two types.
