Answer:
the genotype of the parent guinea pigs are as follows:
RrBb (rough, black) and Rrbb (rough, white)
Explanation:
Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.
After making the dihybdrid cross, the probability obtained for each phenotype is given below:
rough black: 
rough white: 
smooth black: 
smooth white: 
Hope that answers the question, have a great day!
The matching DNA strand would be A - T, G - C, A -T, A - T, C - G, or in other words TCTTG (because you had the strand AGTAAC).
Always remember that A pairs with T, G pairs with C, T obviously pairs with A, and C obviously with G.
Answer:
Oxygen (O2) concerntration
Temperature
pH
Answer:
Estimated Guess so D because if there are more then 10 rabbits you do not want to count every single one. So you would look at how many five are and see how many groups look like about 5 and then guess from there. So an estimated guess would quickly and easily get you a decent amount close to counting them.
Hows that for an answer.
