The volume of the unknown solution obtained from the given standard curve is 2.57%
The linear equation produced by the standard curve is :
- y = absorbance ;
- x = concentration in percent (v/v)
Unknown Solution with absorbance value of 0.35 ;
Input the value of y into the equation.
Collect like terms
Divide both sides by 0.136
Hence, percentage by volume of the unknown solution will be 2.57%

Letter A Animals are eukaryotes
Answer;
The human eye contains more rods than cones photoreceptors.
Explanation;
-The retina of the human eye is the back part of the eye that contains the cells that respond to light. These specialized cells are called photoreceptors. There are 2 types of photoreceptors in the retina: rods and cones.
-The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are more numerous than cones in the periphery of the retina. The cones are not as sensitive to light as the rods. However, cones are most sensitive to one of three different colors (green, red or blue).
