Due to generic factors, some people need to limit their exposure to pollen because it aggravates their respiratory systems.

What is Pathogens?

Pathogens are microorganisms, such as bacteria, viruses, fungi, and parasites, that cause diseases in humans, animals, and plants. They are capable of infecting the body and causing illness by invading host cells, tissues, and organs, and disrupting normal physiological processes.

"Generic factors" likely refers to genetic factors, which are inherited traits that can increase a person's susceptibility to certain health conditions or reactions. In the case of pollen allergies, genetic factors can play a role in determining whether a person is more likely to have an allergic reaction to pollen or not. Allergies are caused by an overreaction of the immune system to harmless substances, and this response can be influenced by genetic factors.

The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).

Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

Answer:

Explanation:

An increase in temperature can have both positive and negative effects on glucose production.

The relationship between temperature and glucose production in the Calvin cycle during carbon fixation is complex and depends on various factors, including the rate of carbon dioxide (CO2) fixation, the rate of oxygen (O2) consumption, and the rate of RuBP regeneration. However, in general, an increase in temperature can have both positive and negative effects on glucose production.

At lower temperatures, the rate of CO2 fixation may be limited by the rate of enzyme activity, while the rate of O2 consumption may be limited by the rate of respiration. As the temperature increases, the rate of enzyme activity and respiration may also increase, leading to an increase in the rate of CO2 fixation and a decrease in the rate of O2 consumption. This could result in an increase in glucose production.

As the temperature continues to increase, the rate of CO2 fixation may eventually become limited by the rate of RuBP regeneration, while the rate of O2 consumption may increase to the point where it begins to interfere with the reaction between CO2 and RuBP. In this case, further increases in temperature may actually reduce glucose production.

Fossils provide solid evidence that organisms from the past are not the same as those found today.

Fossil fuels are formed from the decomposition of buried carbon-based organisms that died millions of years ago. They create carbon-rich deposits that are extracted and burned for energy. They are non-renewable and currently supply around 80% of the world's energy.

Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers.

Fossil fuels are combustible, burning in the presence of oxygen and forming water vapor, carbon dioxide, ash and other byproducts. Their ability to burn comes largely from their carbon content.

The given question is incomplete, the complete question is:

Consider a scenario where a native plant population is growing at it's carrying capacity in a community. The seed of an invasive species is brought in by a squirrel, which then germinates, grows and reproduces resulting in the establishment a population of this invasive plant species. The invasive species has very similar niche as the native plant species. How do you predict the native plant population to be affected by the presence of this invasive species?

The invasive species fitness will be limited by the native plant species

The native plant carrying capacity will go down, relative to that prior to the invasive species arrival

There will be no change to the native plant population

The invasive species will grow unchecked and exponentially

No listed answer is correct

Answer:

The correct statement is the fourth one, that is, the invasive species will grow exponentially and unchecked.

Explanation:

The fitness of the invasive species will not get restricted by the native species. Though the opposite takes place as the original niche of the local species does not possess the natural predator for the invasive species. Therefore, invasive species emerge fitter and reproduce exponentially without population control.

The carrying capacity of the native species will not go down before the arrival of the invasive species, however, will go down post its arrival.  

As the invasive species has no natural predators, one can witness a substantial reduction in the population of the local plant population. The invasive species will utilize the niche of the local plant, therefore, resulting in the reduction of the native species population, as they have share habitat, food resources, and other natural resources.  

It is correct that the invasive species will grow without any control. An outbreak of invasive species generally takes place due to the absence of its natural predators in the ecosystem at the time of its introduction. Hence, the correct statement is the fourth one.

Invasive species establish in a new area, overgrow, and negatively interact with native species. The correct option is  4). The invasive species will grow unchecked and exponentially

-----------------------------------

Let us firts reviw some framework.

When talking about dispersion, we refer to the change in a species' range or distribution area.

When species move and establish in a new area, out of their original distribution range, they might be considered exotic or invasive, according to their

• reproductive rate,

• population growth, and

• interaction with native species.

The introduction of invasive species has ecological, economic, socio-cultural consequences.

Once an invasive species has been established, it overgrows.

In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-.

These factors favor their establishment because they are adapted to surviving under harder conditions.  

They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-.  

They can also become significant predators of native species, consuming a wide diversity of prey items, and in many cases, there are no native species that may prey on them.

They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species.

They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.

As they expand, they can also affect human in an economic manner and has socio-cultural effects. Many invasive species might cause crops loss by eating cultures. They attack farm animals. They affect buildings and other structures or ships by eating wood. They might even attack humans and cause health problems.

According to this information, we can answer the question.

We need to predict how NATIVE species are affected by INVASIVE species.

The options are,

1) The invasive species fitness will be limited by the native plant species

When talking about invasive species, this is not an option. Invasive species always affect the fitness of native species. So this option is not correct.  

2) The native plant carrying capacity will go down, relative to that prior to the invasive species arrival

The carrying capacity will still be the same. But resources availability will decrease faster because both species have the same requirements. They compete for the same resources. This option is not correct.

3) There will be no change to the native plant population

The will occur changes for the native population for sure. It will be affected by the presence of invasive species. So this option is not correct.  

4) The invasive species will grow unchecked and exponentially

Invasive species population will express an uncontrol exponential growth during its establishment phase.

This plant species find the perfect conditions to reproduce and increase its population size.

It finds available space, no predators, water and nutrients availability, proper light exposure, among others.

They can successfully compete with native species, displacing them and getting more space.  

THIS IS THE CORRECT OPTION
