In a group of rainbow trout, some individuals have a greenish-brown body and others have a blue body. In this group, the gene for the body color trait has two alleles. The allele for a
greenish-brown body (B) is dominant over the allele for a blue body (b).
This Punnett square shows a cross between two rainbow trout.

do you need the explaination?

True or false:   the purpose of a defense mechanism is to get uncomfortable feelings out into the open so they can be dealt with in a healthy manner.indeed true: )

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it

The answer is a. that is an exothermic reaction which means it produces heat
