Yes, it is possible.
However, this is only possible if BOTH of the parents have a recessive allele for blue eyes, i.e. they're heterozygous.
Let only one gene is controllable of the eye color. Let the brown eye dominant allele be R and blue recessive be r. So, only if both parents have the genotypes of Rr, they can produce a baby with rr due to random selections at meiosis, and the baby phenotype would be blue eyed.
If they're both RR or at least one is, the chance of having a blue-eyed baby is impossible.
Answer:
Option A) Protein carrier
Explanation:
The carrier proteins are those proteins that are involved in transfer of substances from one side to other side through plasma membrane. These are present in chloroplast, mitochondria and nucleolus.
The lipid carriers increases the absorption and solubility. These allows the transfer of non-polar molecules. The lipid carriers are used in drug delivery systems. So, this is an incorrect option.
The Porin carriers are present in the membrane of the bacteria. It allows the passive diffusion of molecules due to its large size. It only allows movement of hydrophillic substances.
The Polar molecules and ions moves across the biological membrane with the help of protein carrier. Thus, option A is correct.
Answer:
The mass of salt water is 390 grams
Explanation:
To calculate the mass of salt water, we use the equation:
\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}Density of substance=
Volume of substance
Mass of substance
Density of salt water = 1.30g/cm^31.30g/cm
3
Volume of salt water = 300 mL = 300cm^3300cm
3
(Conversion factor: 1mL=1cm^31mL=1cm
3
)
Putting values in above equation, we get:
\begin{gathered}1.30g/cm^3=\frac{\text{Mass of salt water}}{300cm^3}\\\\\text{Mass of salt water}=(1.30g/cm^3\times 300cm^3)=390g\end{gathered}
1.30g/cm
3
=
300cm
