The fossil record

This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.There are gaps in the fossil record because many early forms of life were soft-bodied, which means that they have left few traces behind. What traces there were may have been destroyed by geological activity. This is why scientists cannot be certain about how life began.

Fossils provide a snap shot of the past and allow us to study how much or how little organisms have changed as life developed on Earth.

The scale of model is of local park  is 1:21

This means that each dimension of the model is 21 times smaller than the actual park (to be developed in future)

Curly hair (C) is dominant over straight hair(c). a heterozygous curly haired woman marries a homozygous straight haired man. wi
omeli [17]

The woman's genotype is Cc (she's heterozygous)

The man's genotype is cc (he's homozygous)

If you make a punnet square it'll look like this (I hope it works out)

    <u>C</u>     <u>c</u>

<u>c</u>  <em>Cc   cc</em>

<u>c</u>  <em>Cc  cc</em>

Since curly hair (C) is dominant, any genotype with a capital C will have curly hair. This means 2/4 or 50% of children will have curly hair
