Answer:
Over the past several years, the misuse of opioids – ranging from prescription painkillers to black tar heroin – has reached epidemic proportions. In 2015, the Media Research Center reported that drug overdoses had surpassed motor vehicle accident fatalities nationwide for the first time. Since 1999, nearly 200,000 Americans have died from a prescription drug overdose. Heroin use increased in response to advocate and lawmaker efforts to restrict overprescribing, doctor shopping, and opioid sales via online pharmacies. As prescription drug overdoses fell from 2010 to 2015, the number of heroin overdoses tripled.
Opioids are synthetic or semi-synthetic substances originating from the poppy plant. Examples include heroin, Fentanyl, and prescription opioid painkillers, all of which operate in the same fashion, albeit with varying degrees of strength. Synthetic opioids are among the most dangerous and addictive. The synthetic opioid Fentanyl, for example, is 25 to 50 times more potent than heroin, which is a semi-synthetic substance.
The National Institute on Drug Abuse explains, “[Opioids] act by attaching to specific proteins called opioid receptors, which are found on nerve cells in the brain, spinal cord, gastrointestinal tract, and other organs in the body.” When substances attach to these receptors, they change how the brain perceives pain and instead produce feelings of euphoria. They also slow essential body functions, such as heart rate and breathing.

Which of the following groups of organisms uses sunlight to convert carbon dioxide and water into sugar and oxygen?
a. producers
b. decomposers
c. carnivores
d. herbivores
The group of organisms which uses sunlight to convert carbon dioxide and water into sugar and oxygen are producers. Thus, the correct option is A.
What are Producers in the ecosystem?Producers are any kind of green plants present in the ecosystem. Green plants make their own food by using the sunlight (solar energy) and carbon dioxide gas from the atmosphere with the energy to make sugar. The plant uses this sugar (carbohydrate), also called as glucose to make many different products, such as wood, leaves, roots, and bark.
This process through which plants produce their food is called photosynthesis. Photosynthesis occurs only in the plants which have chlorophyll pigment (chloroplast).
Therefore, the correct option is A.

These grasslands can be found in Minnesota in a variety of habitats, including shortgrass prairies perched high on the bluffs of the Minnesota River, enormous fields of big bluestem up to 8 feet tall, and sparsely vegetated sand dunes.
The Great Plains are made up of the Canadian provinces of Alberta, Manitoba, and Saskatchewan as well as the American states of North Dakota, South Dakota, Montana, Nebraska, Kansas, Oklahoma, Texas, Wyoming, Colorado, and New Mexico.
Sheep are currently the animal raised on prairie terrain. Millions of prairie dogs and thousands of bighorn sheep were nourished by vast, uninterrupted horizons of continuous grasslands.
Additionally plentiful were the birds, which included more than 3 billion passenger pigeons, various grouse species, and greater prairie chickens.

Part1: Compare the relative concentrations (amount of GtC) of at least six (6) components of the carbon cycle
(e.g. The ____ has less GtC carbon than the ______ .)
Part 2: Explain how the total amount of matter is conserved during the carbon cycle.
hint-the earth is a closed system
Answer:
Explanation:
PART 2 : The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle.
Because elements are neither created nor destroyed under normal circumstances, individual atoms that compose living organisms have long histories as they cycle through the biosphere. In this depiction, a carbon atom moves from coal buried beneath the Earth's surface to a power plant and into the atmosphere. It eventually dissolves in water and is taken up by an algal cell, where it is then consumed by a copepod.

Calculate the rate of photosynthesis(mm/hr) for Elodea if when measuring net photosynthesis, the water level moved up 5 min and, when measuring cellular respiration it took 20 minutes for the water level to move down 1mm.
63mm/hr
57mm/hr
67mm/hr
61mm/hr
52mm/hr
Answer:
Net photosynthesis- 3mm/20min- 1.5mm/10min
Cellular respiration- 1mm/15min- 0.66mm/10min
Gross photosynthesis = Net photosynthesis + Cellular respiration = 1.5+0.66 = 2.16 (mm/10min)
Rate of photosynthesis = (gross photosynthesis)6 = 2.16 *6 = 12.96 mm/hr
As we are measuring rate of photosynthesis in hr ,we should multiply gross photosynthesis with 6 (as we measured gross photosynthesis for 10 min).

There are approximately 259 hectares per square mile. How many deer could a square mile of forest of mature American chestnut trees support for a year if they were the only organism consuming their nuts?
Answer:
25 deers
Explanation:
According to studies conducted by wildlife experts, a single deer needs roughly 25 acres of land in order to survive comfortably. Therefore we first need to find out how many acres are in a hectare, which based on a quick search online we see that 25 acres equal 10.11 hectares which is what a single deer needs to survive. Now we divide the total amount of hectares by the hectares a single deer needs in order to find out how many deers can survive on this total amount of land.
259 / 10.11 = 25.618
Finally, we can see that the 259 hectares can maintain roughly 25 deers.
