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.

Answers

Answer 1

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.

Blood pressure decreases with distance from the left ventricle of the heart

Answers

Blood pressure decreases with the distance from left ventricle of heart as the decrease in the diastolic pressure is greater than increase in systolic pressure.

What is diastolic pressure?

Diastolic pressure is the pressure exerted in the arteries as the heart rest between the beats.

The decrease in a diastolic pressure is greater than the increase in systolic pressure. This results in an increase of the pulse pressure gradually.

As a result of this, arterial blood pressure decreases in the systemic arteries as the distance from the heart increases.

Thus, blood pressure decreases with distance from the left ventricle of the heart.

Answers

Answer:

obesity increases blood pressure

Explanation:

This is because the high fat percentage in the body has lead to a build up of fat on the inside of arteries and this makes them thinner. the heart has to pump harder to get the blood around the body and through these, now smaller arteries. therefore yes having diabetes does increase blood pressure.

60:4

After that you simplify the ratio which should end up with the final ratio being:

Explain how the shape and stacking of the thylakoids contributes to the rate of carbon fixation by the chloroplast.

Answers

Chloroplast is the cell organelle that is associated with photosynthesis as it has chlorophyll. When stacked, each thylakoid increases its total surface area, allowing for more electron transport chains to be embedded in each thylakoid membrane.

What is thylakoid?

Inside chloroplasts, thylakoids are membrane-bound compartments which are the site of photosynthesis's light-dependent reactions.

Thylakoids are made up of a thylakoid membrane that surrounds a thylakoid lumen. Its main function is to allow the light reactions of photosynthesis.

When the thylakoids are stacked, each of them is able to increase their total surface area which leads to more electron transport chains being embedded into each thylakoid membrane.

Thus, it can be concluded that the shape and stacking of the thylakoids contributes to the rate of carbon fixation by the chloroplast by allowing more electron transport chain.
