When mRNA is coded into amino acids (protein) by the ribosome. Name the process.

What acts like the scissors that cut the DNA?

Where is the most biomass found?

It only takes ONE of these in order for a trait to be expressed.

What needs to happen first in order for a species to speciate? 

"Panthera tigris" ...Panthera is the

During Meiosis we double up the DNA

Which is not true when it comes to DNA and RNA

What is most specific?

Different forms of the same gene

When mom and dad's genes mix and match together.

Why is there less biomass at the top trophic levels?

Mom's homozygous dominant for brown eyes, dad's homozygous for blue eyes. eye color for kids?

Which is an example of a density-dependent limiting factor?

How does a disease become less deadly over time? 

When you put DNA from two different organisms together it is called..

An organisms 'job' in an ecosystem is called

When you have the same alleles from mom and dad you are said to be..

When an ecosystem can only support a limited amount of a certain species

This trait will only be expressed if TWO of the same gene are present 

Mode of selection? In a population having large beaks becomes favorable over medium beaks.

organisms with different structures, but all have the same function must have adapted to a

A new river forms and divides a population, this is what type of isolation?

Dark and light colored mice live in a dark environment, the light colored mice are eaten.

If a group of organisms have similar bone structure, then they may all have a common __________

Why is crossing over so important?

When new species arise from old ones, this is called

How do we naturally achieve variation?

organisms with the same structures but different function (same bones, different job)

Organisms with the best traits to survive will live and pass those traits on to their offspring

Why don't we look exactly like our siblings?

What is some evidence for evolution?
