It can also be called a column.
Explanation:
It correctly reads;
A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:
1. Explain why the energy transfer is not the same between the three tests of the experiment.
2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.

Answer:
I need more info? Is this a question or a true or false thing?
Explanation:
The answer is B) roan x roan.
Let's summarize:
R - dominant allele,
r - recessive allele,
<u>RR </u>- dominant homozygous with <u>red color</u>,
<u>rr </u>- recessive homozygous with <u>white color</u>,
<u>Rr </u>- heterozygous with <u>roan color</u>.
If we cross two heterozygous (Rr):
Parents: Rr x Rr
Offspring: RR Rr Rr rr
then, the offspring will be: <u>1 red</u> (RR) : <u>2 roan</u> (Rr, Rr ) : <u>1 white</u> (rr).
