Answer:
The correct answer to the following question will be "Tests or experiments".
Explanation:
Descriptive investigations attempt to build assumptions from either the predictions of the phenomena, even as experimentally investigated were mostly designed to allow the research scientist to make comparisons under various situations with both the control behavior.There are indeed enough that-called comparison investigations, that also gather information analyze varying environments but don't even include the regulate location.So that the above would be the appropriate answer.

Select the correct text in the passage. Which part or parts of the paragraph indicate that the government will enforce a particular environmental policy?
1.Factories are entitled to tax credits if they adhere to pollution control levels stipulated by the concerned administrative body.
2.They are allowed to function for an additional two hours per day during summers.
3.They are not allowed to employ children below the age of 18 as laborers.
4.Factories that emit higher amounts of pollution will be subject to penalties.
Answer:
1.Factories are entitled to tax credits if they adhere to pollution control levels stipulated by the concerned administrative body.
4.Factories that emit higher amounts of pollution will be subject to penalties.
Explanation:
Environmental policy is a term that refers to the guidelines established by governments or companies in order to preserve the environment in relation to the impacts that industrial activities can cause.
The two sentences above represent a specific environmental policy, because both refer to the reduction of pollution caused by companies during their activities. In addition, the phrases above show the punishments and reimbursements that compliance and non-compliance with this policy will bring to the company.

What is DNA sequencing?DNA sequencing refers to the overall laboratory technique for figuring out the precise sequence of nucleotides, or bases, in a DNA molecule. The series of the bases (regularly mentioned by means of the primary letters of their chemical names: A, T, C, and G) encodes the organic statistics that cells use to expand and operate.

Answer: Glaze storm
Explanation:
A storm is a disturbed weather condition which is developed due to unstable wind currents. The center of wind currents are in low pressure whereas the surrounding are at high pressure. This condition forms clouds called cumulonimbus.
A glaze storm can be defined as a precipitation event in which the ice coating is formed on the exposed objects by the freezing of supercooled water deposited by the rain or fog on the surface.

Explanation:
A. One of the late symptoms of MN is excessive edema, or build up of fluid within the interstitial space of tissue. Explain how loss of circulating blood protein (hypoalbuminemia) would cause edema with respect to hydrostatic and colloid osmotic pressure within capillary beds throughout the body.
Answer:
Albumin is a protein that attracts water in the compartment where it is found, that is why when circulating within the blood vessels the blood volume is maintained by this protein, so that the liquid or fluid that makes up the blood volume is retained within the capillaries due to hydrostatic forces and because the albumin protein is hydrophilic.
The albumin is decreasing, that is, in deficit or hypoalbulinemia, less water reaches the blood compartment, therefore the blood pressure or pressure will drop, the blood volume will decrease but not due to loss of it as in hemorrhages, but due to diffusion to other compartments. VASCULAR through the processes of OSMOSIS, in simple words, when this protein descends, water filters from the blood vessels to extravascular compartments, this phenomenon clinically manifests itself as EDEMA.
Explanation:
Hypoalbulinemia also occurs in severe nutritional disorders where ovalbumine is not consumed through the egg, since the person's diet is severely lacking, generating massive edema in the abdominal area or abdominal distension.
The effect that the plasma liquid has in spreading to extravascular spaces is called OSMOSIS, which draws water from the external environment by the oncotic pressure generated by other proteins.
The oncotic pressure is the pressure that is generated when the water diffuses from one compartment to another by attraction of a protein, it happens both with albumin and with other proteins of the organism that are characterized by being hydrophilic or attracting water.
Hypoalbulinemia destroys severe cardiac symptoms due to the high demand that an increase in edema and difficulty of venous return entail along with the fall in blood pressure.

Summarize the flow of carbon, oxygen ,water, nitrogen, and phosphorus through an ecosystem. ( Minimum of three paragraphs please)
Answer:
Water is the basis of all living processes. More than half of the human body is made up of water, while human cells are more than 70 percent water. Thus, most land animals need a supply of fresh water to survive. However, when examining the stores of water on earth, 97.5 percent of it is non-potable salt water. Of the remaining water, 99 percent is locked underground as water or as ice. Thus, less than 1 percent of fresh water is easily accessible from lakes and rivers. Many living things, such as plants, animals, and fungi, are dependent on the small amount of fresh surface water supply, a lack of which can have massive effects on ecosystem dynamics. Humans, of course, have developed technologies to increase water availability, such as digging wells to harvest groundwater, storing rainwater, and using desalination to obtain drinkable water from the ocean. Although this pursuit of drinkable water has been ongoing throughout human history, the supply of fresh water is still a major issue in modern times.
Carbon, the second most abundant element in living organisms, is present in all organic molecules. Its role in the structure of macromolecules is of primary importance to living organisms. Carbon compounds contain especially- high forms of energy, which humans use as fuel. Since the 1800s (the beginning of the Industrial Revolution), the number of countries using massive amounts of fossil fuels increased, which raised the levels of carbon dioxide in the atmosphere. This increase in carbon dioxide has been associated with climate change and other disturbances of the earth’s ecosystems. It is a major environmental concern worldwide.
The carbon cycle is most easily studied as two interconnected sub-cycles: one dealing with rapid carbon exchange among living organisms and the other dealing with the long-term cycling of carbon through geologic processes.
Getting nitrogen into the living world is difficult. Plants and phytoplankton are not equipped to incorporate nitrogen from the atmosphere (which exists as tightly-bonded, triple-covalent N2), even though this molecule comprises approximately 78 percent of the atmosphere. Nitrogen enters the living world via free-living and symbiotic bacteria, which incorporate nitrogen into their macromolecules through nitrogen fixation (conversion of N2). Cyanobacteria live in most aquatic ecosystems where sunlight is present; they play a key role in nitrogen fixation. Cyanobacteria are able to use inorganic sources of nitrogen to “fix” nitrogen. Rhizobium bacteria live symbiotically in the root nodules of legumes (such as peas, beans, and peanuts), providing them with the organic nitrogen they need. Free-living bacteria, such as Azotobacter, are also important nitrogen fixers.
Phosphorus is an essential nutrient for living processes. It is a major component of nucleic acid, both DNA and RNA; of phospholipids, the major component of cell membranes; and, as calcium phosphate, makes up the supportive components of our bones. Phosphorus is often the limiting nutrient (necessary for growth) in aquatic ecosystems.
Phosphorus occurs in nature as the phosphate ion (PO43−). In addition to phosphate runoff as a result of human activity, natural surface runoff occurs when it is leached from phosphate-containing rock by weathering, thus sending phosphates into rivers, lakes, and the ocean. This rock has its origins in the ocean. Phosphate-containing ocean sediments form primarily from the bodies of ocean organisms and from their excretions. However, in remote regions, volcanic ash, aerosols, and mineral dust may also be significant phosphate sources. This sediment then is moved to land over geologic time by the uplifting of areas of the earth’s surface.
