Answer:

Niche diversification.

Explanation:

It is niche diversification because it is an hypothesis that indicate that every species is most superior in competition in by making use of resources in the niche they occupy at equilibrium or balance.

Some species divide their niche resources into variation for the to exploit it.

Answer and Explanation:

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.

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

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).

Answer:

QP = 41

Explanation:

Its geometry its easy...

Since its getting cut through the middle that means they equal each other

3x + 5 = 5x - 19 (Use a calculator)

x = 12

Since your solving to find QP you plug it into QP

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.

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.

why would this organism a close ancestor of humans evolve differently than us.

Answer:

1. Nucleolus- inside of the nucleus, makes ribosomes

2. Rough Endoplasmic Rectilium(Rough ER)- synthesizes proteins, has sibosomes

3. Smooth Endoplasmic Rectilium(Smooth ER)- does not have ribosomes, produces protein and lipid(fat)

4. Vacuole- stores water, sugar, and pigment

5. Chloroplast- photosynthesis happens here

6. Cell Wall- provides support

7. Membrane- controls what goes in and out of the cell

8. Mitochondria- power house of the cell, produces power from chemical energy

9. Golgi Bodies- Prepares proteins and lipids for the inside an outside of the cell

10. Ribosome(the little black dots)- attaches to Rough ER, transfer RNA to protein(protein synthesis),

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.

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.

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.

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).

Bioaccumulation can be defined as the process of accumulation of chemical nocive substances in biological systems.

In conclusion, mercury can accumulate in biological systems and then pass to humans after consumption (e.g., fish consumption).
