1. Air quality – The higher the population in a city the higher the chances of reduced air quality due to increase per capita emissions.
2. Water usage – The higher the population density in a city, the harder it is to supply adequate clean water to everybody and the water quality may begin to drop
3. Waste management- Pollution begins to become a problem when the population in a city goes beyond its carrying capacity.
4. Land use – Urban sprawl becomes a problem when a high proportion of the city’s population is squeezed in a small portions of land
Answer:
False, I got it right on my test
Answer:
The correct answer is - high specific heat.
Explanation:
Water atoms are polar, so they structure hydrogen bonds. This gives water remarkable properties, for example, a moderately high specific heat, density, adhesion, and cohesion.
A water particle comprises of two hydrogen iotas clung to an oxygen molecule, and its general structure is bowed. Oxygen even bonding with hydrogen have two sets of unshared electrons. The entirety of the electron pair and unpaired repulse one another.
Water's high specific heat is a property brought about by hydrogen holding among water particles. At the point when warmth is assimilated, hydrogen bonds are broken and water atoms can move uninhibitedly. At the point when the temperature of water diminishes, the hydrogen bonds are shaped and discharge a lot of vitality.
Thus, the correct answer is - high specific heat.
Answer: The correct answer is-
an agent that causes a mutation in DNA.
Mutagen is an agent or a substance that causes permanent change in the genetic material of living organisms ( DNA, deoxyribonucleic acid). This process is called mutation.
A mutagen can be a chemical, physical or biological agent that causes mutation in the DNA.
Example- Physical agents such as -
- Ionizing radiations like alpha particles, gamma rays, X-rays that brings break in the DNA and cause other damages.
- Ultraviolet radiations that creates pyrimidine dimers ( T=T) and causes replication errors if damage is not repaired.
The monomer must be able to form stable covalent chemical bonds between units in order to polymerize.
