Explain why Mendel obtained a 3:1 ratio for various traits during his hybrid crosses of pea plants?
repeat the test several times
It has a nucleus
independent - number of nails, dependent - whether the balloon pops or not
analyze results
A virus is a strand of RNA or DNA surrounded by a layer of protein.
incomplete dominance
The first plants were true-breeding plants, resulting in heterozygous plants that then creates a 3:1 ratio
The flowers were all purple
Which of the following is NOT a characteristic of an archaea cell?
repeat the test several times
It has a nucleus
independent - number of nails, dependent - whether the balloon pops or not
analyze results
A virus is a strand of RNA or DNA surrounded by a layer of protein.
incomplete dominance
The first plants were true-breeding plants, resulting in heterozygous plants that then creates a 3:1 ratio
The flowers were all purple
A cross between a plant with red flowers and a plant with white flowers produces offspring with pink flowers. What is this an example of?
repeat the test several times
It has a nucleus
independent - number of nails, dependent - whether the balloon pops or not
analyze results
A virus is a strand of RNA or DNA surrounded by a layer of protein.
incomplete dominance
The first plants were true-breeding plants, resulting in heterozygous plants that then creates a 3:1 ratio
The flowers were all purple
Look at the image on page 19. What color flowers did Mendel discover were produced in the first generation?
repeat the test several times

A virus is a strand of RNA or DNA surrounded by a layer of protein.
incomplete dominance
The first plants were true-breeding plants, resulting in heterozygous plants that then creates a 3:1 ratio
The flowers were all purple
Organizing results into a table, graph, or chart is done during which step of a scientific inquiry?
repeat the test several times

Which statement is true about viruses?
repeat the test several times
It has a nucleus
independent - number of nails, dependent - whether the balloon pops or not

Start with 2 identical balloons, a board with 50 nails on it, and a board with a single nail on it. Press a balloon to the single nail and a balloon to the 50 nails. The single nail will pop the balloon and the other will not. Name the variables.

It has a nucleus
independent - number of nails, dependent - whether the balloon pops or not
analyze results
A virus is a strand of RNA or DNA surrounded by a layer of protein.
