Identify the type of neuronal cell that detects bright light and provides high-resolution color vision.
alina1380 [7]

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.

Paraphin [41]

Answer:

IF mold is added to a bacteria culture, THEN the mold will produce a chemical that will kill the bacteria.

Explanation:

A hypothesis is a testable explanation to an observed problem. A possible solution or possible answer given to a question or problem, which can be tested via experimentation is referred to as HYPOTHESIS. The hypothesis is usually written in an IF, THEN format.

According to this question, a scientist (identified to be Fleming) hypothesized that the mold must be producing a chemical that killed the bacteria and tested it by setting up an experiment whose result turned out to support his hypothetical claim.

Therefore, his hypothesis in an IF, THEN statement is:

IF mold is added to a bacteria culture, THEN the mold will produce a chemical that will kill the bacteria.
