Answer:
The correct option is b. cones.
Explanation:
Cones and rods are specialized cells, called photoreceptor cells, that are found in the retina and are responsible for our vision.
Cones, allow to the human eye to have a visual acuity (ability of the eye to resolve, transmit sharp images and perceive small details in an object) and provide sensitivity to the color, are more concentrated in the central yellow spot known as the macula.
There are three different types of cones in color reception: "L cones" (sensitive to long wavelength, which is red), "M cones" (sensitive to medium wavelength, which is green) and "S cones" (sensitive to short wavelength, which is blue). Since color perception depends on the activation of these three types of nerve cells, it follows that the visible color can be determined based on three numbers called triestimulus values.
The rods are necessary for the perception of light and darkness and to adapt to night vision, because they are very sensitive to low intensity light. On the contrary, they become completely blind to bright light and, therefore, lack importance with regard to daytime vision or visual acuity.
Translocation is the movement of materials from leaves to other tissues throughout the plant. Plants produce carbohydrates (sugars) in their leaves by photosynthesis, but nonphotosynthetic parts of the plant also require carbohydrates and other organic and nonorganic materials.
Answer:
Matter is the smallest particle of an element
Compounds is a mixture of two or more element
Like all other heterotrophs, it eats and goes through cellular respiration.
The three parts of the cell theory are as follows: (1) All living things are made up of cells, (2) Cells are the smallest units (or most basic building blocks) of life, and (3) All cells come from preexisting cells through the process of cell division.
