Discuss one issue that Alaska and the Artic are facing due to Climate Change. To possibly earn full points, you need to include 3-5 thoughtful sentences on the issue. Include what the issue is and how it is impacting Alaska and the Artic.

Answers

One issue that Alaska and the Artic are facing due to Climate Change is that ground ice becomes prone to thaw and collapse, which impact in life of people inhabiting these regions.

What is Climate Change?

The term Climate Change makes reference to the sudden modification on the weather condition on the Earth over the past few decades, whose velocity of change is increasing and it is considered to be caused by human activities that generate global warming such as the burning of fossil fuels for industrial purposes.

In Alaska and the Artic, the melting ice is causing many problems associated with daily life in these regions The ground ice known is melting, and thereby structures on the surface may collapse due to this phenomenon.

Therefore, with this data, we can see that Climate Change causes the ice in the ground ice to thaw and thus collapse.

Biological transmission differs from mechanical transmission in that biological transmission?

a. occurs when a pathogen is carried on the feet of an insect.
b. involves reproduction of a pathogen in an arthropod vector prior to transmission,
c. works only with noncommunicable diseases.
d. requires direct contact

Answers

Biological transmission differs from mechanical transmission in that biological transmission option B: involves reproduction of a pathogen in an arthropod vector prior to transmission.

When a pathogen reproduces inside a biological vector that spreads it from one host to another, it is said to have undergone biological transmission. The primary carriers of biological transmission are arthropods.

The fundamental distinction between mechanical and biological transmission is that during mechanical transmission, agents are simply transferred from an infected host or contaminated substrate to a susceptible host. During biological transmission, the agent develops and/or propagates within the vector.

Answers

Spartina is a plant that grows in salt marshes. It stores salt in its roots, making the root have a higher salt concentration than the water around them.  Water moves into the roots is most likely to occur in response to this concentration of salt in the roots.

The grass family taxon Spartina is typically seen in coastal salt marshes.  One or two species also occur on the western coast of North America and in freshwater habitats inland in the Americas. Its species, also known as cordgrass or cord-grass, are native to the coasts of the Atlantic Ocean in western and southern Europe, north-western and southern Africa, the Americas, and the islands of the southern Atlantic Ocean. The east coasts of North and South America, notably Florida, have the greatest species variety. Particularly in coastal salt marshes, they establish sizable, frequently dense colonies and expand swiftly. The species' height ranges from 0.3-2 m. Several of the species will create hybrids if they interbreed.

The propensity of Spartina species to hybridize is widely documented. Late in the eighteenth century, S. Southern England unintentionally received alterniflora from North America. It quickly bred with the only local species, S, here. maritima produced a sterile but robust hybrid known as Spartina X townsendii that had the ability to propagate vegetatively (as can all Spartina species). This hybrid eventually underwent chromosomal duplication, becoming fertile. Although Spartina townsendii var. anglica is the preferred name for this species, it is also referred to as S occasionally. anglica, which is now the predominant Spartina species in the majority of salt marshes in the United Kingdom.

85f equals to how many c?

Answers

85 degrees fahrenheit =

85°F is approximately equal to 29.4°C.

To convert Fahrenheit (°F) to Celsius (°C), you can use the following formula:

°C = (°F - 32) * 5/9

Using this formula, to convert 85°F to Celsius:

°C = (85 - 32) * 5/9

°C = 53 * 5/9

°C ≈ 29.4

This conversion is often used when dealing with scientific or international temperature scales, or when comparing temperatures in different geographic locations. It is important to remember that Celsius and Fahrenheit are two different temperature scales, Celsius is used extensively around the world while Fahrenheit is used more frequently in the United States and some other countries.

The factors that increase a community's diversity are the age of the community; Energy input and Human activity.

There are many ways to describe diversity. Assuming that diversity is defined broadly, as opposed to, say, genetic diversity, there are many things that can influence the diversity of a group.

The diversity may be impacted by the landscape's complexity, the community's age, and its surroundings.

Diversity will be impacted by the diversity of the habitat or landscape itself. There isn't much possibility for variety if the habitat is continually boreal forest, with the same species distribution and composition throughout.

It is a crucial source of renewable energy, and depending on how solar energy is captured, distributed, or transformed into solar power, its technologies can be roughly categorised as either passive solar or active solar.

Utilizing concentrated solar power, photovoltaic systems, and solar water heating are examples of active solar approaches.

Mitosis helps sequoia tree become so big in the following way: Mitosis makes more cells to repair or replace dead or damaged cells, and it makes more cells to help the tree grow (option C).

What is mitosis?

Mitosis is the division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by cell division.

Mitosis is opposed to meiosis, which is a cell division that produces gametes by the dividing a diploid cell into four haploid cells.

Mitosis is retains the number of chromosomes of the parent cell in the offsprings. Mitosis describes the duplication and distribution of chromosomes, the structures that carry the genetic information.

One of the major functions of mitosis is the repair or replacement of damaged cells, hence, by so doing creates more and more cells that makes a living organisms grow in size.

Substance A is converted to substance B in a chemical reaction. it adjusts the ph of the reaction medium. this statement best describes the role of an enzyme during this reaction.

What is ph?

The H+ ion concentration's negative logarithm is known as pH. As a result, the meaning of pH is justified as the strength of hydrogen.

Although less apparent, the mathematical definition of pH is more beneficial overall. It claims that the pH is equal to the negative logarithmic value of the hydrogen ion (H+) concentration.

[H+] = -log pH

The pH of a water source depends on how acidic or alkaline it is. The activity of the hydrogen atoms determines the pH level since this activity is a reliable predictor of the acidity or alkalinity of the water. The pH scale has a range of 0 to 14, with 7.0 being neutral, as may be seen below. According to conventional wisdom, water with a low pH is acidic, whereas water with a high pH is basic (alkaline). The pH of pure water should be 7.0, however because of the impurities in the water, water supplies appears acidic.
