The DNA in our cells nucleus is wrapped around proteins called histones, forming chromosomes which in turn codes for our genes.
<span>Respiration is the process that is utilized by all living cells in order to create energy. The process is usually carried out in the presence of oxygen (aerobic respiration) but can also take place in the absence of oxygen (anaerobic respiration). Therefore the answer in this case is false.</span><span />
Parent #1 has the alleles of IA and i
Parent #2 has the alleles of IB and i
A punnet squares is a simple diagram that illustrates the possible genotypes of the offspring of these two people.
Parent #1 is across the top and Parent #2 is along the side
IA i
IB AB IBi
i IAi ii
For IA or IB will be dominant to i. So for phenotype purposes their offspring have a 25% chande of being AB, 25% chance of B, 25% chance of A and a 25% change of type O (ii)
I believe the correct answer from the choices listed above is the second option. <span>The building blocks of a habitat consist of environmental factors. Hope this answers the question. Have a nice day.</span>
