The answer is <span>The increased nitrates from the fertilizers leech into the water and cause algal blooms, which take oxygen out of the water and this suffocates fish.</span>.
Algae blooms are the consequence of large amounts of farm
fertilizers in the rivers, which increases nitrates level in the water. Algae use the presence of increased nutrients
and enhance their own growth. It is known that they produce
an oxygen in the photosynthesis, so it is not a problem while they are
still alive. But when these organisms die, their decomposition begins. For the
process of decomposition, the oxygen is needed and ultimately it will be depleted
from a body of water. This could lead to the death of aquatic animals, such as fish, that
depend on oxygen.
The greenhouse effect is an essential phenomenon for life on earth. However, human activities such as pollution and burning of fossil fuels have caused an intensification of this effect, which has harmed the atmosphere and is directly related to global warming.
The greenhouse effect is formed by a layer of atmospheric gases that settle around the planet and allows a temperature suitable for life to reach the earth's surface. Therefore, we can guarantee that this effect is essential for our survival. It is necessary that the amount of these gases is kept in equilibrium for this temperature to be constant.
However, the burning of fossil fuels, industrial activities, pollution (caused by vehicles, aerosols, fires, among others), the use of non-renewable energy releases greenhouse gases into the atmosphere daily and in large quantities.
This causes the layer of greenhouse gases that circulates the earth to become more and more expanded, not being able to disperse solar radiation easily and causing an increasing temperature. All that heat is retained in the atmosphere, thus generating global warming, which allows the planet's temperature and ocean water to increase dramatically, which can cause various harmful effects to life on the planet.
For this reason, it is necessary to carry out public policies that reduce pollution and encourage the use of clean and renewable energy that does not increase the layer of greenhouse cases, promoting well-being and life on earth.
. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. ... Mutations: In this interactive, you can “edit” a DNA strand and cause a mutation.
The change in internal energy of this gas sample is equal to: c. 715 J.
<u>Given the following data:</u>
- Quantity of heat = 874 J.
<h3>What is the First Law of Thermodynamics?</h3>
Mathematically, the the First Law of Thermodynamics is given by this formula:

Where;
is the change in internal energy.
- Q is the quantity of heat.
Substituting the parameters into the formula, we have;

Change in internal energy (ΔH) = 715 Joules.
