Answer:
The correct answer is: 2) According to the given data, the surface area of all erythrocytes is (4.74x10^9)/(100x10^8)m^2. This is almost half of the surface area formed by a monolayer as Gorter and Grendel estimated it, leading to the conclusion that the surface of each cell was covered with two layers of lipids.
Explanation:
Each erythrocyte has a surface of 100 μm^2, which is equal to 100x10^-8 m^2. And to calculate the total area of erythrocyte counted, you should multiply the number of cells with the surface of one cell. This is (4.74x10^9)*(100x10^-8), which is equal to (4.74x10^9)/(100x10^8)=0.47m^2. This is approximately half of the surface area formed by the monolayer that was estimated. This is evidence that allows to conclude that the erythrocyte membrane is a bilayer
Answer:
There is no control.
Explanation:
If the scientist was testing something based on the different temperatures, they would need the amount of time in the oven to be the same for each cookie so that they can compare them. Without the times being the same, the scientist would not be able to tell whether the temperature or the time in the oven caused the differences in the cookies.

Answer: The correct answer is- to see what new traits might appear next.
As per the information in the question, pigeon breeder selects the offspring of pigeons with spotted bodies.
Spotted body is a trait that would be depicted by two different alleles ( such as one for black and other for white color).
As both the alleles for the color are represented in the pigeon offspring, therefore, it is a case of co-dominance ( let us take its genotype as Bb, where 'B' is allele for black and 'b' for white color).
When pigeons with spotted bodies are cross bred, they can produce pigeon with spotted and non spotted ( such as black 'BB', white 'bb', or spotted 'Bb' ) body depending upon the allele that is passed to the offspring.
Thus, pigeon breeder selects the spotted bodies pigeons and then breed those offspring to see what new traits might appear next.
