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).
Hypothesis: If i increase the amount of string then the salt will dissolve faster
Independent variable: the amount you stir the liquid
Dependent variable: the time it takes to dissolve the salt
Materials: you need a beaker, salt, water, and a stir rod.
One is to involve exercising curiosity in order to ask questions and seek answers about the universe.
<span>6CO2 + 6H2O ==> C6H12O6 + 6O2</span>
<span>carbon dioxide + water ==> glucose +oxygen</span>
<span>The correct answer to this question is a line graph. If Rob needs to create a graph that is able to display the combination of two different values - in this case, level to which the salt has dissolved and time taken - and he needs to have more than one result included, then a line graph is the way to present this.</span>
