The Maine Department of Transportation (DOT) has a fleet of roughly 400 plow trucks that are used to control snow and ice on approximately 8300 lane miles of Maine’s state roads. They usually plan on an average of about 30 treatable events in a winter. This includes the use of rock salt, salt brine and winter sand, a mix of sand and salt. Salt brine is used on roads and bridges prior to a storm to delay ice and snow from sticking to the roadway and is also used in plowing to fight the buildup of ice and snow throughout the storm. Rock salt helps keep roads safe when winter storms hit, reducing winter road accidents, but it can also have negative effects on plant life and aquatic ecosystems. What are the environmental effects of salting that must be mitigated? Select ALL that apply.A) Salt kills roadside plants. B) Salt builds up in roadside soil , changing its pH, preventing the growth of plants. C) Salt corrodes metals like automobile brake linings, frames, and bumpers, and can cause cosmetic corrosion. D) Elk, moose and sheep eat road salt causing "salt toxicosis" where they lose their fear of vehicles and humans, causing many fatal encounters. E) Salt doesn't evaporate, or otherwise get removed once applied, so it remains a persistent risk to aquatic ecosystems due to runoff or ground

Salt builds up in roadside soil , changing its pH, preventing the growth of plant and Salt doesn't evaporate, or otherwise get removed once applied, so it remains a persistent risk to aquatic ecosystems due to runoff or ground are the environmental effects of salting that must be mitigated. That is option B and E.
The effects of road salting on the environmentRoad salting is a technique that is used to melt snow and ice during winter season. This keeps the streets and side sidewalks clear and prevents slick driving conditions.
The types of salt used for road salting include:
rock salt, salt brine,winter sand, a mix of sand and salt.The impact of road salting on the environment include the following:
Decrease in reproduction and growth of plants: This is because increase salinity are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.Negative effect on aquatic ecosystems: This affects mostly the freshwater ecosystems as high levels of salt are very toxic to the aquatic organisms.Learn more about aquatic ecosystems here:

Answer:
the chloroplasts of the plant cell
Explanation:
how does urbanization cause air pollution
.Answer:Concentrated energy use leads to greater air pollution with significant impact on human health. Automobile exhaust produces elevated lead levels in urban air. Large volumes of uncollected waste create multiple health hazards. Urban development can magnify the risk of environmental hazards such as flash flooding.
Explanation:
differentiate between the chromosome theory of inheritance and the gene chromosome Theory
Answer:
The Chromosomal Theory of inheritance, proposed by Sutton and Boveri, states that chromosomes are the vehicles of genetic heredity. Neither Mendelian genetics nor gene linkage is perfectly accurate; instead, chromosome behavior involves segregation, independent assortment, and occasionally, linkage.
Which group of elements is provided by air and water?
Answer: Over 95 percent of the dry weight of a flowering plant is made up of three elements—carbon, hydrogen, and oxygen—taken from the air and water. The remaining 5 percent of the dry weight comes from chemicals absorbed from the soil.

find the linear equation that models the data in this table.
Linear equations are used to represent relations that have constant rates
The linear regression equation that models the data in this table is [tex]\^y = 2.40476x + 0.33333[/tex]
Regression equation using a graphing calculatorTo calculate the regression equation, we make use of a graphing calculator.
Using the graphing calculator, we have the following data:
Sum of X = 28Sum of Y = 70Mean X = 3.5Mean Y = 8.75Sum of squares (SSX) = 42Sum of products (SP) = 101Formulating the regression equationThe regression equation is represented as:
[tex]\^y = b\^x + a[/tex]
Where:
[tex]b = \frac{SP}{SSX}[/tex] and [tex]a = MY - bMX[/tex]
So, we have:
[tex]b = \frac{101}{42}[/tex]
[tex]b = 2.40476[/tex]
Also, we have:
[tex]a = MY - bMX[/tex]
[tex]a= 8.75 - 2.4\times 3.5[/tex]
[tex]a= 0.33333[/tex]
Hence, the linear regression equation is:
[tex]\^y = 2.40476x + 0.33333[/tex]

1. Why is cell an open dynamic system?
The exchange of matter or substances between the cell and its environment is dynamic as it varies in direction and rate as per the requirements of the cell. Thus,a cell attains a stead -state wherein the internal conditions of the cell remain constant. Hence, cell is considered to be a open dynamic system

Which of the following causes the change from day to night?
Answer:
^
Explanation:
The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.
Which symbol represents a hybrid
Explanation:
The three standard sex symbols are the male symbol ♂ and the female symbol ♀, and the hybrid symbol ×. They were first used to denote the effective sex of plants (i.e. sex of individual in a given crossbreed, since most plants are hermaphroditic) by Carl Linnaeus in 1751.
Explain how natural disasters can change the characteristics of a species for many generations after the disaster. To develop this discussion you will need a minimum of 2 paragraphs.
Answer:
Strong volcanic eruptions and fires can temporarily change regional weather, cooling or heating the air, changing winds, or causing rain. Volcanoes, storms, and floods can kill marine animals directly, or cause long-term problems by depositing debris and affecting the temperature and salinity of water.
Natural disaster especially such as forest fires and hurricanes have the potential to threaten these endangered species to the point of extinction. ... The fires destroy the animals habitats including their homes, nesting grounds, food, and winter shelters.
After a natural disaster, the community will often go through ecological succession and return to the state it was pre-diaster. Healthy ecosystems will bounce back, as natural disasters have occurred on earth for a long time. ... Healthy ecosystems are adapted to withstand natural disasters over the long time.

What happens when black holes accrete matter too quickly?
Answer:
These objects are called quasars, or active galactic nuclei. However, most black holes are too compact to pull such material — which is mostly gas — in immediately. ... Eventually, the gas is moving so fast that it gets extremely hot and luminous, generating radiation that we can often see from Earth.

Describe the steps of a muscle contraction.
(1) A message travels from the nervous system to the muscular system, triggering chemical reactions.
(2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction.
(3) When the nervous system signal is no longer present, the chemical process reverses, and the muscle fibers rearrange again and the muscle relaxes.
