the noniflower is a plant that grows in soil with a ph of 7.4 to 8. a variation of this species, called the
mariflower, can grow at a more acidic ph. researchers observed an area where noniflowers typically
grow over a period of 50 years. their data showed that the number of mariflowers slowly increased and
the number of noniflowers slowly decreased. the impact of environmental factors on this trait shift was
also documented.
explain why an increase in precipitation and in the number of nearby factories has a greater impact
on the occurrence of the mariflowers than changes in temperature, length of day, and invasive
species.
Factories increase pollutants in the atmosphere. Liquid deposition by the increase in precipitation causes soil acidification. Mariflower plants' growth is favored over noniflower plants.
What is soil acidification?Environmental acidification is a process produced by a decrease of pH in the environment mainly due to pollution increase.
Soil and water lose their neutralizing capacity, increasing sulfuric and nitric acids released to the environment by different sources.
In nature, there is a natural release of sulfur and nitrogen oxides. However, the concentration of these gases in the environment is sharply increased by anthropogenic sources -like factories-.
Sulfur and nitrogen oxides react with radical hydroxyls and atmospheric water vapor to become sulfuric and nitric acids, respectively.
These acids are dissolved in atmospheric water drops that drive them to the ground. This event is known as liquid deposition and can be caused by rains (acid rain), snow, dew, or fog.
Also, a fraction of these acids return to the Earth's surface as gases or aerosols. This phenomenon is called dry deposition, which occurs more frequently near the sources.
Usually, rainwater pH is about 5.6.
However, with high concentrations of acids in the environment, rainwater pH decreases.
When the the rain gets to the ground, they produce a series of chemical changes that alter the natural pH of the soil and water and have a consequent effect on ecosystems.
The main acidification agents are sulfur dioxide (SO₂) and nitrogen oxides (NOₓ), and to lesser extent ammonia (NH₃).
Factories, among many others, are a significant anthropogenic source of pollution.
In the exposed example, we know that
The increase in precipitations and the number of factories had a high impact.
Temperature, length of days, and presence of invasive species had a low impact.
From this information, we can exclude temperature, length of days, and invasive species as significant variables influencing the noniflower and mariflower plants' growth.
According to the information provided before, we can assume that factories are the pollution sources that release nocive gases to the environment.
In the area near these factories, dry deposition might occur. The increase in precipitation means an increase in liquid depositions because a higher concentration of acids reaches the soil dissolved in water drops.
Liquid and dry deposition near factories cause soil acidification.
Noniflower plants can not grow in acid soils, so their reproductive and survival rates decrease. The number of noniflowers plants slowly decreases fear the factories. Mariflowers plant, on the other hand, grows in acid soils. They turn to be favored by the acidification caused by factories' pollution. The number of mariflowers slowly increase.Factories increase the concentration of pollutants like SO₂ and NOₓ in the atmosphere. Liquid deposition caused by the increase in precipitation causes soil acidification. Both events favor mariflower plants' growth over noniflower plants.

What might happen to the rate of diffusion if the blood flow were to speed up?
Answer:
Diffusion rate increases
Explanation:
The rate of diffusion would increase as a steep concentration gradient is maintained so more nutrients/ glucose diffuses quickly. This is also how the small intestines are adapted to have efficient diffusion rates as there are many capillary networks that allow lots of blood flow, increasing diffusion rates.
