construct a model of gas exchange that shows interactions among: air sacs (alveoli) of the lungs, capillaries, artery, vein, red blood cell, and body cell. Include the gases oxygen (O2) and carbon dioxide (CO2), as well as arterial blood and venous blood, in your model. All these structures must be labeled or annotated in your model.

Answer:

Which of the following statements about exponential growth curves is true?

- a. Exponential growth curves are common for R-selected species.

Explanation:

The statement that is true about exponential growth curves is as follows:

Thus, the correct option for this question is A.

An Exponential growth curve may be defined as a type of growth curve that significantly illustrates greater increases in the population of organisms with respect to time. It immediately represents the growth with extreme fast rates.

Exponential growth is followed by the continuous breeding population which contains more individuals than a similar population breeding annually. It includes examples like some insects, r-selected species, etc.

The shape of the exponential growth curve is J-shaped. It represents only fast growth rates. While the logistic growth curve shows fast growth rates followed by slow growth rates. It possesses a shape known as S-shape. It represents the growth rate of k-selected species.

Therefore, the correct option for this question is A.

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

5) No listed answer is correct

Explanation:

The heart tone “lub,” or S1, is caused by the closure of the mitral and tricuspid atrioventricular (AV) valves at the beginning of ventricular systole.

The heart tone “dub,” or S2 ( a combination of A2 and P2), is caused by the closure of the aortic valve and pulmonary valve at the end of ventricular systole.

Answer: D - Bivalves have an open circulatory system, cephalopods have a closed circulatory system

Explanation: I had to research the differences to find the answer

A difference between bivalves and cephalopods are bivalve animals use a radula to feed, and cephalopods use filter-like structures to feed, that is the third option, where they both belong to the Mollusca phylum.

Both bivalves and cephalopods belong to the mollusca phylum, and they are invertebrates, some of the bivalves, such as oysters and mussels, are important as they are a source of food for humans and as filter-feeding organisms; at the same time, squid and octopus are cephalopods. These organisms are significant in different fields of study, such as neuroscience and evolution.

Hence, a difference between bivalves and cephalopods are bivalve animals use a radula to feed, and cephalopods use filter-like structures to feed, that is the third option, where they both belong to the Mollusca phylum.
