Antimycin A Antimycin A is used in catfish farming: added to the water at 10 ppb, it kills small fish but does not harm catfish. Thus, small fish die out, and catfish get all the resources. When Antimycin A is added to isolated mitochondria, NADH and succinate both accumulate. However, if ascorbate, an artificial redox mediator that transfers electrons to cytochrome c, is added, oxygen consumption is still observed. Which step in the respiratory chain is antimycin A likely to inhibit (1 pt)

Answers

Answer:

Inhibits electron transport chain in mitochondria.

Explanation:

Antimycin A inhibits electron transport chain which leads to the complete halt of electron transport in mitochondria. due to this inhibition of electron transport chain in mitochondria leads to the killing of the fishes except catfish and so the catfish increase in population due to more resources and no competition. this Antimycin A is highly toxic for fishes and kill all fishes if used at the amount of 10 ppb.

What is Wind?

Wind is defined as the natural movement of air or other gases relative to a planet's surface which occurs on a variety of scales, from thunderstorms lasting tens of minutes, to land masses lasting a few hours. The wind blows warm air from the poles towards the equator on the surface of the Earth.

Global winds result from differences in the absorption of solar energy between climate zones on Earth, to local breezes that results from the warming of land surfaces. Gentle or moderate wind is known as the breeze while strong and gusty wind is known as the storm, when accompanied by thunder and lightning and small gusts of wind moving at high speed are known as gusts.

So, the correct option is B.

Explanation:

What type of variation is nessary for natural selection to occur

Answers

Answer:

Genetic variation

Explanation:

Genetic variability (diversity) stems from two basic processes: mutation and recombination.

If there were no mutations, all genes would exist in only one form, they would not have alternative forms.

Since phenotypic variability also depends on genetic variability, it is clear that the processes of mutation and recombination contribute to the creation of a large number of different phenotypes.

A plasmid that encodes resistance to ampicillin and tetracycline is digested with the restriction enzyme PstI, which cuts the plasmid at a single site in the ampicillin-resistance gene. The DNA is then annealed with a PstI digest of human DNA, ligated, and used to transform E. coli cells. (a) What antibiotic would you put in an agar plate to ensure that the cells of a bacterial colony contain the plasmid

Answers

Answer:

tetracycline

Explanation:

When the DNA insert is ligated in Pstl site, the ampicillin gene is disrupted while tetracycline gene is still intact.

- If the bacterial colony is growth in a medium with only ampicillin, only the cells that contains the plasmid with the insert will grow.

- If the bacterial colony is growth in a medium with only tetracycline, the cells which have incorporated the plasmid will survive. We cannot distinguish between cells with plasmid + insert and plasmid alone.

- If the bacterial colony is growth in a plate with ampicillin + tetracyclin, only the cells with the plasmid without the insert will grow.

Therefore, to ensure that the cells of a bacterial colony contains the plasmid, they have to be seeded in a plate with tetracycline.

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 invasive plant population to be affected by the presence of this native species

Answers

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

In Leonardo da Vinci’s time, nobody knew that the arteries were joined to the veins by tiny, invisible capillaries. This means that even though he studied the heart in detail, he thought that the arteries and veins were dead ends. Why did this make it difficult for him to understand how the heart worked?

Answers

Answer:

It was difficult for him to understand how the heart worked because he wasn't fully aware of the pumping mechanism of the heart and how the circulation of blood goes inside the body. Not seeing the capillaries meant that the heart pumped blood towards the vessels and into a dead end. He couldn't understand where the blood that was being pumped goes to.

Explanation:

Leonardo da Vinci is considered one of the earliest persons to study the heart. Although he made an exceptional observation of the different parts of the heart, he couldn't track the capillaries. He didn't know that these tiny structures connected the arteries and the veins. He believed that the heart was meant to transfer heat from the liver going to the muscles. He also believed that the lungs helped cool the blood.

Which of the following factors most likely triggers arousal from hibernation?

A) the sun rising in the morning B)snow falling onto the ground
C) the environmental temperature dropping below 0 °C
D) a significant decrease in the animal's respiration rate

Answers

Answer:

A) the sun rising in the morning

Explanation:

In biology, hibernation refers to a physiological state where a plant or animal is metabolically inactive in the winter period (characterized by extreme cold). As far as the animal or plant is concerned, the cold weather during winter is an adverse condition, hence, they undergo hibernation in order to conserve their energy.

According to this question, arousal or wakening from hibernation would be triggered in the presence of heat source, which in this case is the SUN RISING IN THE MORNING.
