Urban sprawl refers to the expansion of poorly planned, low-density, auto-dependent development, which spreads out over large amounts of land, putting long distances between homes, stores, and work and creating a high segregation between residential and commercial uses with harmful impacts on the people living in these areas and the ecosystems and wildlife that have been displaced. Although some would argue that urban sprawl has its benefits, such as creating local economic growth, urban sprawl has many negative consequences for residents and the environment, such as higher water and air pollution, increased traffic fatalities and jams, loss of agricultural capacity, increased car dependency, higher taxes, increased runoff into rivers and lakes, harmful effects on human health.

It has been found that the rainforests are accountable for about one-third, that is, 28 percent of the oxygen of the Earth, however, the majority of the oxygen, that is, about 70 percent in the atmosphere is generated by the marine plants. The left-over two percent of the oxygen comes from other sources.
The majority of the oxygen comes from the tiny plants in the ocean known as phytoplankton, which lives near the surface of the water and drifts with the currents. Similarly to plants, they perform the process of photosynthesis, that is, they utilize carbon dioxide and sunlight to prepare food, oxygen is the by-product of photosynthesis.
However, the concentration of the dissolved oxygen, which the water can hold relies on the salinity and temperature of the water. The cold water can withhold more oxygen in comparison to warm water and fresh water can hold more oxygen in comparison to salt water. So, the warmer and saltier the water is, the less will be the oxygen dissolved in it.
Assuming the body weight of the woman is 67 kg, milligrams of digoxin required per day for the woman will be 3.25 milligrams.
<h3>What is drug dosage?</h3>
Drug dosage refers to the amount of drug required to be administered to a patient per given time based on body weight or age.
The dosage for digoxin for treatment of heart failure for the 67 year old woman is 48.5 mcg/kg body weight.
Assuming the body weight of the woman is 67 kg, milligrams of digoxin required per day for the woman will be 48.5 * 67/1000 = 3.25 milligrams.
In conclusion, the dosage of drugs depends on age and body weight.

Hi there!
Plants are primary producers.
Hope this helps :D
1. The strength of magnetic field at A is 64 unit, then the magnetic field strength at B. is 256 units.
64 × 64 = 256 units.
2. If the strength of magnetic field B is 6 units then the strength magnetic field at A is 24 units.
which is 256 : 4 = 16 units.
Magnetic field is one of the two ways where the intensity of magnetic field is being expressed.
