what are the steps involved in the scientific method
in 1907, Duncan preformed a series experiments in which he attempted to measure the weight of a soul as it left a dying person in his experiment McDowell cool place a dying person on a scale and measure their weight immediately prior to the following death. McDowell determined the change and weighed approximately 21 grams for the experiments he concluded the soul exists and has mass what is the fundamental scientific flaw in his conclusions
Answer:
The flaw is that he is studying pseudoscience (fake science) and he did not repeat his experiments in any form of trials.
In what form does carbon move from the atmosphere into the biological
food webs?
Answer:
Carbon enters all food webs, both terrestrial and aquatic, through autotrophs, or self-feeders. Almost all of these autotrophs are photosynthesizers, such as plants or algae. Autotrophs capture carbon dioxide from the air or bicarbonate ions from the water and use them to make organic compounds such as glucose.
Can an enzyme be recycled? Explain.
Answer:
Enzymes serve as catalysts to many biological processes, and so they are not used up in reactions and they may be recovered and reused. However, in a laboratory setting, reactions involving enzymes can leave the enzyme unrecoverable. This process makes the enzyme at once less reactive but more stable.

Mercury is a toxin that is of significant concern due to biomagnification. Explain how mercury found in an aquatic environment can accumulate in
biomagnification, and explain how limiting consumption of large predatory fish, such as swordfish, may be necessary for individuals trying to avoid high
mercury concentrations
Answer: Mercury has been well known as an environmental pollutant for several decades. As early as the 1950's it was established that emissions of mercury to the environment could have serious effects on human health. These early studies demonstrated that fish and other wildlife from various ecosystems commonly attain mercury levels of toxicological concern when directly affected by mercury-containing emissions from human-related activities. Human health concerns arise when fish and wildlife from these ecosystems are consumed by humans.
During the past decade, a new trend has emerged with regard to mercury pollution. Investigations initiated in the late 1980's in the northern-tier states of the U.S., Canada, and Nordic countries found that fish, mainly from nutrient-poor lakes and often in very remote areas, commonly have high levels of mercury. More recent fish sampling surveys in other regions of the U.S. have shown widespread mercury contamination in streams, wet-lands, reservoirs, and lakes. To date, 33 states have issued fish consumption advisories because of mercury contamination.
These continental to global scale occurrences of mercury contamination cannot be linked to individual emissions of mercury, but instead are due to widespread air pollution. When scientists measure mercury levels in air and surface water, however, the observed levels are extraordinarily low.
Explanation:
Mercury can accumulate in biological systems and then pass to humans after consumption (in this case, fish consumption).
What is bioaccumulation?Bioaccumulation can be defined as the process of accumulation of chemical nocive substances in biological systems.
Mercury is a toxic metal that bioaccumulates in life forms such as fish and then passes to humans, which is a serious threat to health.In conclusion, mercury can accumulate in biological systems and then pass to humans after consumption (e.g., fish consumption).

The monosaccharide serves as the building block of glycogen, a polymer made up of many glucose molecules. So, the correct option is (B).
What is Polymer?A polymer is defined as a substance or material consisting of very large molecules known as macromolecules, which are made up of many repeating subunits. Due to their wide spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.
During the process of polymerization, polymers are formed in which smaller units known as monomers are joined together with the help of covalent bonds. Polymers are of four types:
1. Natural
2. Synthetic
3. Addition
4. Condensation
In above given example, Monosaccharide which is glucose is the monomer which is joined together to from glycogen which is a polymer.

If an antiport carrier moving solutes in opposite directions across a cell membrane without requiring energy, this is called
Answer: Countertransport
Explanation:
Cotransport is a type of active transport of substances through a biological membrane. It is characterized by the simultaneous transport of two or more substances, hence its name, and is common in small organic molecules, such as glucose or amino acids, especially in epithelia of absorption and secretion, such as the small intestine and renal tubules. The cotransport can be of two types, simporte or antiport.
Simporte: the two transported molecules move in the same direction, for example both are transported into the cell. Antiport: the two molecules move in the opposite direction, one towards the outside of the cell and the other towards the inside.In both cases, one of the substances moves in favor of its gradient and the other against it. In electrochemical gradients there is potential energy stored and when a substance moves in favor of its gradient this energy is released.
In contransport, the transmembrane protein responsible for co-transportation, is able to use the energy stored in the electrochemical gradient of a substance to move the other substance against its gradient. The electrochemical gradient from which the energy for transport comes is maintained by ATPases, which consume ATP. Since the co-transporter does not directly consume ATP, the co-transport is classified as secondary active transport, while the ATPases perform primary active transport. So, ATPases consume energy to create a gradient and then co-carriers use the energy from the gradient to transport another substance.
In the case of Countertransport, the cell transports two types of molecules in the opposite direction across the membrane. Countertransport is a type of antiport exchange. The key point regarding countertransport is that it transports ions or molecules in opposite directions. Thus, one molecule leaves the cell while the other enters at the same time through the membrane. In addition, this is a type of secondary active transport that uses electrochemical gradient to drive the movements (as it was explained before). Countertransport can mediate the exchange of the same solutes or different solutes. The sodium-calcium exchanger, the Na+ / H+ exchanger and the Cl- / bicarbonate exchanger are examples of countertransport.

An acid has a pH that is less than 7. A base has a pH that is greater than 7. Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.
Situation 1: Base
Situation 2: Acid
Situation 3: Acid
Situation 4: Base
Situation 5: Acid
Situation 6: Base
A. Water directly out of the tap has a pH of 7.2. When you add carbon dioxide (blow into the water), you get a pH of 5.1. This means that the addition of carbon dioxide makes water more acidic.
B. The most basic solution will have the highest pH. This means that it will be water with bleach added to it.
C. The most acidic solution will have the lowest pH. This means that it will be water with instant coffee.
