the chestnut blight, a fungal parasite, eliminated nearly all adult chestnuts and spread unchecked through the eastern united states. this was most likely due to which of the following?

Answers

Answer 1

The chestnut blight most likely spread unchecked through the eastern United States due to the lack of natural resistance in the American chestnut trees. The fungus was able to infect and kill nearly all adult chestnuts, leading to a decline in their population.

Additionally, the lack of effective control measures at the time also contributed to the spread of the disease. Overall, the chestnut blight was a devastating event for the American chestnut tree population and had long-lasting impacts on the ecosystem.

This was most likely due to a lack of natural resistance in the chestnut population, introduction of the pathogen from a different region, and insufficient preventative measures taken to control the spread of the disease.

Answers

Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms that regulate the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should.

the connection between limiting factors and invasive species

Answers

Answer:

Biology, Ecology, Earth Science, Climatology, Geography

Explanation:

A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor. Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor. There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support

Answers

Answer:

Explanation:yeah

The correct answer is New World monkey as is observed in South America. It has a prehensile tail, spends most of its time in the trees, and is fairly small.

On one hand, a few species of New World monkeys own prehensile tails, which means they are able to use their tails to understand or maintain directly to objects (2). Their tails can resource those monkeys in locating and consuming meals withinside the cover in addition to transferring among the trees, as their tails offer greater help and balance.

The formal time period for the taxonomic organization containing all of the New World Monkeys (NWMs) is Platyrrhini. The NWMs diverged from the Old World monkeys and apes (Catarrhini) round forty million years ago (Perelman et al. 2011). Ancestral species are idea to have migrated to the Americas on rafts of plants or through island hopping (Fleagle 2013). The extant species of NWMs are presently labeled into 5 families, twenty genera, 156 species, and 204 taxa. However, the taxonomy of numerous taxa is debated withinside the literature and, therefore, this type is concern to change.

What is the New World monkey living area?

Many of the monkeys scampering across the forests of Central and South America have some thing unique on their butts-- a further hand. Well, now no longer exactly. It's a prehensile tail-- a greedy appendage that enables the animals navigate the tall and treacherous cover on the lookout for end result and leaves .

Hence concluded that the New World monkey have a prehensile tail, spends most of its time in the trees, and is fairly small.

PHET Energy Skate Park Simulation .Consider this equation: gravitational potential energy = mgh. Which of those variables is changing as the skater moves up and down the track?

Answers

Answer:

h - height

Explanation:

gravitational potential energy = m * g * h

m stands for mass. Mass doesn't change in physics

g stands for gravitational acceleration. It is a constant.

h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.

In the equation gravitational potential energy = mgh, the variable that is changing as the skater moves up and down the track is the variable h, which represents the height or vertical position of the skater.

As the skater moves up the track, the height increases, resulting in a higher value for h. Conversely, as the skater moves down the track, the height decreases, leading to a lower value for h.

The other variables in the equation, m (mass) and g (acceleration due to gravity), typically remain constant unless specified otherwise. Therefore, the changing variable in this equation as the skater moves up and down the track is the height (h).

Taking into account the definition of Avogadro's number, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.

Avogadro's Number

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance.

Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Amount of moles in this case

In this case, you have 2 moles of Fe(NO₃)₂.

Then you can apply the following rule of three: If 1 mole of the compound contains 6.023×10²³ molecules, 2 moles of the compound contains how many molecules?

amount of molecules= (6.023×10²³ atoms× 2 moles)÷ 1 mole

amount of molecules= 1.2046×10²⁴

Finally, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.
