The correct answer among the choices listed above is option C. The amount of carbon dioxide in the atmosphere has <span>increased</span> since industrialization began in the nineteenth century. This is because more carbon dioxide is emitted by machines in plants and by the vehicles.
Most people in the world get our water from rivers and lakes, including the vast majority of the world’s poorest people.
But half of the world’s 500 most important rivers – water sources for hundreds of millions of people – are being seriously depleted or polluted.* Approximately 40 percent of the rivers in the U.S. are too polluted for fishing and swimming.**
Water shortages will likely be a fact of life for most people on the planet within the next ten years.*** We can’t afford to pollute and destroy our drinking water sources. But that’s exactly what we’re doing – often without knowing it.
Forests, grasslands and wetlands are nature’s water filters. They help keep erosion and pollution from flowing into our waters and they slow rainwater down, sending more water into underground supplies. But every year we lose 32 million acres of forest – that's a lot of water filters, gone, every year.
We are facing dirtier, unsafe water and more risk of water shortages and scarcity. This crisis is real, it’s happening now and it’s getting worse fast.
The Nature Conservancy partners with people communities in all 50 states and 30 countries to protect water sources. We work on the ground to:
<span><span>Prevent deforestation and destruction of grasslands – nature’s water filters</span><span>Restore forests and grasslands that have already been lost or damaged and sending erosion into our waters</span><span>Equip farmers with practical ways to keep harmful run-off out of our waters</span><span>Restore floodplains that act as sponges and send water down into groundwater supplies and filter pollution out of rivers</span><span>Create new science that helps pinpoint the greatest threats to our waters and the most effective ways to combat them</span></span>
But we understand that nature won’t solve everything, so we’re finding new ways to reduce water use. More than 70 percent of water withdrawn from nature goes to agriculture, so we’re helping farmers access new technologies and practices that use less water while continuing to produce the food we need.
Answer: The role of substance A in photosynthesis is: it combines with water to form glucose.
Explanation:
Answer:
The purpose of colorful petals is to attract insects
Answer:
Electron transfer to from cytochrome c to molecular Oxygen in the process of oxidative phosphorylation
Explanation:
Cytochrome c is a protein which is involved in the electron transport chain for the production of ATP molecules during then process of respiration. It a soluble protein found in the intermembrane space of the mitochondria. It receives electrons from ubiquinone at Complex III of the electron transport chain and transfers this electron to molecular oxygen through its interaction with complex IV or cytochrome c oxidase, reducing molecular oxygen to water.
If the interaction of cytochrome c with cytochrome c oxidase is inhibited, the process of elctron transfer to oxygen will be inhibited and, so ATP synthesis will cease.
Ultimately, respiration will be inhibited resulting in death of the organism. For example, cyanide inhibits cytochrome c oxidase resulting in death of the organism poisoned with cyanide.
