Both are 50%, this is because Rr is dominant in a purple stem and rr is recessive in a green stem. By crossing these plants Rxr= Rr and rxr= rr.
<span>Active and passive transport help to maintain homeostasis because they transport fluid/water/materials across the plasma lemma (cell membrane). All of these materials need to exist in certain ratios for the cell to function properly. </span>
1)Enzyme is a protein. The main material of an enzyme is protein
2)It is easily influenced, by environmental change. Environmental factors include temperature, pH, and inhibitor.
3)It acts as catalyst The enzyme functions in accelerating chemical reaction, but the enzyme itself does not change after the reaction ends.
The bell shaped curve indicates polygenic traits. A polygenic trait is controlled by multiple alleles. Hope this makes sense :)
