Answer:
False
Explanation:
It is true that water moves from an area of higher water concentration to an area of lower concentration.
Based on osmotic pressure, water always moves from an area of higher concentration to that of lower concentration.
- Osmosis of water and liquids is made possible across a concentration gradient.
- Water is driven from one place to another via concentration gradient.
Answer:
Covalent
Explanation:
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.
Answer:
A - 1. Carbon dioxide is converted to sugar used for food (this is process of phosynthesis).
G - 2. Carbon trapped in fossil fuels is converted to carbon dioxide (this is combustion of fuel).
E - 3. Organic carbon is converted to fossil fuels.
H - 4. Carbon dioxide is converted to carbonates.
F - 5. Sugar is broken down and converted to carbon dioxide (this is breathing).
Explanation:
Answer:
Sunlight
Explanation:
On the surface of the earth, the main thing affecting ear is sunlight. While it does provide energy for living things, it drives our planet's weather and climate with temperature in the atmosphere and our oceans.
Dozens of tower cranes dot DC's skyline, and so many of them are building new high-rise apartments that the District now ranks ninth among US cities with the most housing units under construction. It sure looks like a lot of new housing supply is being built, and certainly plenty of new luxury apartments within the District. However, the downtown high-rises under construction only tell half the story of Greater Washington's housing growth story.
While all those cranes are easy to see from afar, what isn't immediately apparent from the airport (but might be from a plane) is that many fewer acres of the countryside around us are being bulldozed for subdivisions–which for the past century has been where most lower-cost, low-rise housing was built. As a result, the region as a whole isn't building enough housing for our rising population.
Reducing sprawl is good, but we haven't built enough housing in city cores to meet demand
Fewer than half as many single-family houses are being built at the suburban fringes of Greater Washington every year, compared to the region's long-range average. Taken together, the single-family houses that aren't being built around Greater Washington each year would cover four square miles–an area the size of Rock Creek Park. The slower pace of suburban development over the past ten years has meant tens of thousands of acres of farms and forests around our region haven't been bulldozed for subdivisions and strip malls.
