The answer is B because if you recross them you get the same answer Rr and rr so the correct answer is B
<span>I believe the answer is A. hydrophobic. Inside the biological membranes are lipids (hydrophobic) molecules. As you may know the membranes are lipid bilayers. In order to place proteins, which are polymers of amino acids, you would need to create an like-to-like environment. The R groups of amino acids will interact with this hydrophobic lipid bilayer environment and will need to display the same characteristics to keep the plasma membrane intact and not cause unwanted disruption. Therefore, R groups of amino acids in biological membranes should be hydrophobic. </span>
Answer: C. 0.4
64% of the population have dominant phenotype which means they’re either BB or Bb. The other 36% of the population have bb genotype. If this population is in equilibrium then f(b)=rad0.36=0.6 and as u know f(b)+f(B)=1. So 1-0.6=0.4.
Hope this helps:))
Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals. Paleomagnetism measures the ancient orientation of the Earth's magnetic field to help determine the age of rocks.
