Suppose I am TASTE testing two types of energy drinks to see what people prefer. 1. What will the Idependent variable be ? 2. What will the Dependent variable be? 3 Will the data I collect be Qualitative, Quantitative or both?

Answers

Answer: 1. Energy drink

2. What people prefer to drink.

Explanation:

1.The independent variable can be referred to that variable that can be manipulated in an experiment. The energy drinks can be changed to see that what people prefer to drink.

2.The dependent variable can be referred to that variable which is the result of the experiment it is influenced by the independent variable. What people prefer to drink is the dependent variable.

3.The data being collected in this experiment will be quantitative. As we can calculate the response of people what they prefer to drink in numbers.

In what form does carbon move from the atmosphere into the biological
food webs?

Answers

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.

Some scientists believe Earth's orbit around the sun has changed contributing to global warming.

Answers

No. The Sun can influence the Earth’s climate, but it isn’t responsible for the warming trend we’ve seen over the past few decades. The Sun is a giver of life; it helps keep the planet warm enough for us to survive. We know subtle changes in the Earth’s orbit around the Sun are responsible for the comings and goings of the ice ages. But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth’s orbit, and too large to be caused by solar activity.

Monosaccharides are to polysaccharides as are AMINO ACIDS to PROTEINS.

Polysaccharides are carbohydrates composed of many subunits called monosaccharides, which are linked together by glycosidic bonds.

Proteins are biomolecules consisting of many subunits called amino acids, which are linked by peptide bonds.

Lipids represent a broad class of organic molecules composed of a glycerol backbone that attaches to one or more fatty acids.

Nucleic acids (either DNA or RNA) are biomolecules composed of long chains of nucleotides linked by phosphodiester bonds.

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

Answers

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).

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.

Which monomer serves as the building block of glycogen, a polymer made up of many glucose molecules? Choose 1 answer: (Choice A) Amino acid (Choice B) Monosaccharide (Choice C) Nucleotide (Choice D) Steroid

Answers

Answer is B, monosaccharides

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.

Thus, the monosaccharide serves as the building block of glycogen, a polymer made up of many glucose molecules. So, the correct option is (B).

If an antiport carrier moving solutes in opposite directions across a cell membrane without requiring energy, this is called

Answers

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.
