In the early stages the embryos of four different species will look the same .For example, fish embryos and human embryos both have gill slits. In fish they develop into gills, but in humans they disappear before birth. That what makes them different.
I believe it would be B. More than a year (Since it is a slow change, and that is the longest amount of time). Hopefully this helps
Genotype and the environment both can affect a phenotype.
Phenotype= a physical feature resulting from a certain genotype.
For example, let's say a person born with a genotype pp has the phenotype: pale skin. However, if they live in a sunny environment, then the melanin in their skin will increase over time changing their phenotype to tan skin. Does that make sense as to how both factors can impact phenotype?
<span>Cell membranes contain membrane proteins that allows all the interaction that occurs within the cell. It makes the cell membrane selectively permeable because of its characteristics as being fluid or its fluidity which means to say that they can move freely within the lipid bilayer. The membrane proteins can also be stored in the lipid bilayer together with the enzymes. It cannot be denied that membrane proteins have a lot of functions based on its type. They can be integral proteins, peripheral proteins and lipid bound proteins.<span>
