Basically, areas without much plant life have low chlorophyll concentration. In this case, extreme climates characterizes these areas. Specifically, the desert, polar tundra, and high mountain ridges are three areas which have low chlorophyll concentrations. The main characteristics are that they have no soil, shallow soil, or soil that lacks in nutrients, which makes it not suitable for plants to grow; they also have limited water available. Since chlorophyll is contained in vegetation, any area without plants will lack chlorophyll. Hope this helps!
Answer: Desert, Polar Tundra, and High Mountain Ridges because of lack of soil or nutrient in the soil, and lack of water.

Answer:
- When policies and laws are set at the state or local level, citizens are better enabled to develop the skills, habits, and dispositions necessary for responsible participation in democratic self-government.
- When states maintain a certain amount of autonomy and independence, they are better able to check the power of the central government and thereby preserve liberty.
Explanation:
Government authority is a synonym for power. It is the basis of any kind of hierarchical organization, especially in the political system. It is a kind of power that is continued over time, stabilized and can be characterized as institutionalized or not, in which subordinates render obedience to the individual or institution holding the authority.
Many people advocate government authority in the larger state sphere, meaning they believe it is right that there is less national government authority. For these people, this would be correct because:
- When policies and laws are set at the state or local level, citizens are better enabled to develop the skills, habits, and dispositions necessary for responsible participation in democratic self-government.
- When states maintain a certain amount of autonomy and independence, they are better able to check the power of the central government and thereby preserve liberty.
Answer:
The oblique illumination is
used by the microscopists to resolve N. Spencrii in the Dark Field Condensers.
Explanation:
It was found that the use of oblique light was required to resolve the striae. Oblique illumination was the first step toward dark field microscopy. In dark field, light
seems to radiate from the specimen while all the rest of the field is black. Resolution is as good as that in bright field while contrast is enhanced.
In dark field microscopy, no
direct light from the condenser enters the objective lens. Only light
that is reflected, refracted or diffracted by the specimen enters the objective. The dark field condenser produces a circle of light. The
light is at an extremely oblique angle to the surface of the slide. This
oblique light comes to a focus on the specimen. It then diverges so
strongly that no direct light enters the objective. This type
of illumination is a hollow cone of light.
Answer:
Onload event
Explanation:
Derek Young wants to create a page that would have several dynamic effects. For instance, he wants a clock that shows how long the user has been viewing a page, plus he’d like a welcome message and a goodbye message on the page. He also has a list of links that should run his functions to update parts of the page. Derek will most likely use onload event to display his welcome message?
