Is the space between the bottom of the objective lens and the surface of the slide.
Svetlanka [38]

WORKING DISTANCE is space between the bottom of objective the lens and the surface of the slide.

The distance between front edge of the objective and the lens and the specimen surface ("with the surface of the cover glass in case of the cover glass objective lens") when the specimen is also focused.

The working distance (W.D.) which is determined by the linear measurement of the objective and front lens to the focal plane. In the general, the objective of the  working distance decreases by the magnification and the numerical aperture of both increase. The working distance is the distance and from the front of the lens to be the focal plane

Describes what happens as carbon cycles through the environment. What takes carbon out of the environment? What things put carbo
Citrus2011 [14]

Answer:

Carbon moves through Earth's ecosystems in a cycle referred to as the It is through carbon dioxide gas found in Earth's atmosphere that carbon enters the living parts of an ecosystem. ... To release the energy in food, organisms break down the carbon compounds—a process called respiration.

Photosynthesis removes carbon dioxide naturally—and trees are especially good at storing carbon removed from the atmosphere by photosynthesis. Expanding forests, restoring existing forests and managing forests to encourage more carbon uptake can leverage the power of photosynthesis to convert carbon dioxide in the air into carbon stored in wood and soils. The decompsition of the soil helps create a natural environment which keeps the trees healthy and continuously producing photosynthesis. Direct air capture is the process of chemically scrubbing combustionable carbon dioxide directly from the ambient air, and then storing it either underground or in long-lived products. This new technology is not unlike the carbon capture and storage technology for various emissions sources like power plants and industrial facilities. The difference is that direct air capture removes carbon from the atmosphere instead of consuming emissions.

Carbon dioxide is added to the atmosphere by human activities. When hydrocarbon fuels (i.e. wood, coal, natural gas, gasoline, and oil) are burned, carbon dioxide is released. During combustion or burning, carbon from fossil fuels combine with oxygen in the air to form carbon dioxide. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.If not for the greenhouse effect, Earth would be an ice ball. So, CO2 and other greenhouse gases are good—up to a point. But CO2 is so good at holding in heat from the Sun, that even a small increase in CO2 in the atmosphere can cause Earth to get even warmer.

Hope this helps :)

Based on the model of cellular transport, the hydrolysis of ATP and ADP provide a mechanism for
Ronch [10]

Answer:

<em>Cellular transport is the movement of ions or molecules across the membrane of the cell through either active or passive process.</em>

Explanation:

During active transport, ATP (Adenosine triphosphate) is used. In passive transport, ATP is not used. In active cellular transport, the ions move across the membrane against the concentration gradient.

For ATP to be used, it has to get hydrolyzed thereby forming ADP and inorganic phosphate. On the other hand, ADP captures the energy through the oxidation process taking place in the cell.
