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.
In general, the warm to hot summers and relatively mild winters of the Mediterranean and humid subtropical climates are similar. More people live in humid subtropical regions, which are occasionally invaded by chilly air in the winter.
Overall, this region's winter temperatures are typically 10 to 20 degrees Fahrenheit cooler than those in Mediterranean regions.
Whether or whether the summers are hot or warm in a region with a Mediterranean climate determines the subcategory. In comparison to the dry summer heat of the Mediterranean climate zones, the summers in the humid subtropical zone are equally warm or hot, but they typically have significantly more humidity, resulting in sultry weather that generally feels more uncomfortable.
What is humidity?
The amount of water vapor in the air is known as humidity. The gaseous form of water, known as water vapor, is typically undetectable to the eye. The presence of precipitation, dew, or fog is predicted by the humidity.
The temperature and pressure of the system of interest affect humidity. In comparison to warm air, cool air has a higher relative humidity when the same amount of water vapor is present. The dew point is another relevant variable. As the temperature rises, more water vapor is required until saturation is reached. A parcel of air will eventually approach saturation as its temperature drops, without adding or losing water mass. A parcel of air can include a wide range of water vapor concentrations.

Answer:
A system in dynamic equilibrium will have small changes that sum together to produce no net change. Dynamic equilibrium is different from a static equilibrium, in which the parts do not move once they've reached equilibrium.
Explanation:
PCR is a laboratory technique used to make multiple copies of a segment of DNA. PCR is very precise and can be used to amplify, or copy, a specific DNA target from a mixture of DNA molecules.
