our bodies need essential fatty acids that are found in unsaturated fats we must consume. which essential fatty acid is called alpha linolenic acid and is found in fish and flaxseed oil?

Answer: Solar energy

Explanation:

The water and wind cycle is driven by the solar energy. The solar energy evaporates the water from the water bodies like oceans, rivers, lakes, and ponds and from other sources of water.

The earth's surface absorbs the heat radiations from the solar energy and the air above the earth's surface get hotter due to absorption of heat.

The coffee cup calorimeter is considered an isolated system. In terms of energy transfer, this means that there is no heat exchange between the system and its surroundings.

The heat capacity of a calorimeter is the amount of heat energy required to raise its temperature by 1°C. It is important to determine the heat capacity of the calorimeter because it allows the accurate measurement of heat transfer in chemical reactions.

By measuring the heat capacity of the calorimeter, one can account for the heat absorbed by the calorimeter itself during the reaction and obtain the correct enthalpy change

Answer:

The correct answer is D.) the curved surface of Earth.

Explanation:

The intensity of sunlight on Earth is affected by the curved surface of Earth, which causes the sunlight to spread out over a larger area. As a result, the intensity of sunlight is less at any given point on Earth's surface than it would be if Earth had a flat surface. This also explains why the poles receive less sunlight than the equator, as sunlight is spread out over a larger area near the poles due to the curvature of the Earth.

Factors such as the mass of Earth, the speed of Earth, and the number of rotations of Earth do not directly affect the intensity of sunlight on Earth.

Phagocytosis. Big endocytic vesicles termed phagosomes are used in phagocytosis, a specific type of endocytosis, to consume large particles like dead cells and bacteria.

Phagocytosis is the process by which a cell takes in big particles, including cells or other relatively large particles. For instance, a type of white blood cell known as a neutrophil will eliminate the intruders through this mechanism, encircling and engulfing the microbe, which is subsequently destroyed by the neutrophils.

A piece of the plasma membrane's inward-facing surface becomes coated with the protein clathrin in preparation for phagocytosis, which stabilises this area of the membrane. Afterward, the membrane's coated section protrudes from the cell's interior.

Given Proposition: The Shark Population has increased. This is assuming that we only base it off of the given food tree, rather than using the food web, which is more factually correct. This means that the sharks in the area can only eat sea otters, and that sea star populations and sea otters can only eat clams.

1) In this case, the shark population increases. This generally means that the sea otter population by itself has increased, suggesting a positive net change within the given food chain. However, with increased shark populations, would mean a damage to the amount of sea otters in the area. This can create an underpopulation of sea otters, which, if sea stars were not a factor, can mean a increase of clam population.

However.

2) Sea stars are a part of the food chain given. Therefore, it can be suggested that while the sea otter population may stabilize and/or diminish, the sea star has no "predator". This means that with the decrease of the sea otter population, the sea star population may actually grow, as the competition for the same source diminishes. Again, with the demand taking over the need, the sea star population may fall once again due to overfeeding, and essentially starvation.

In essence:

Shark Population: Increased

Sea Otter Population: Decreases (is eaten)

Therefore, Clam Population is speculated to increase.

However, the Sea star population would thereby increase due to having more food.

A larger sea star population in which the clam population cannot sustain would collapse, leading to a fall.

Also, due to the smaller amounts of sea otters in the area, the shark population may also see to an decrease of population, as they die from starvation.

The sea otter population would then stabilize when the predatory amounts or less, and their competition collapses.

Of course, there will always be a "food web". Sea otters do not solely rely on clams, neither do sharks solely rely on otters.

The false statement regarding DNA mismatch repair in E. coli is "If both strands appear to be parental, the mismatch repair system can still repair the mismatch."

In DNA mismatch repair in E. coli, the false statement is that if both strands appear to be parental (correct), the mismatch repair system can still repair the mismatch. In reality, the mismatch repair system relies on the recognition of the parental (correct) strand, which is distinguished by its methylation. The mismatch repair system detects and removes mismatches between the newly synthesized (unmethylated) strand and the parental (methylated) strand.

During DNA mismatch repair, a single mismatch can indeed require the removal and replacement of hundreds of nucleotides on the unmethylated strand. The process involves exonucleases, which are enzymes responsible for removing nucleotides from the end of a DNA molecule. The exonucleases play a crucial role in excising the section containing the mismatched base, followed by DNA synthesis to replace the excised region with the correct nucleotides.

In summary, while the parental strand can be distinguished by methylation, a single mismatch may require the replacement of hundreds of nucleotides on the unmethylated strand, and the process involves exonucleases. However, if both strands appear to be parental (correct), the mismatch repair system does not intervene since it primarily focuses on detecting and repairing mismatches between the parental and newly synthesized strands.

Dimensional analysis is a mathematical technique used to analyze and convert physical quantities by considering their units.

Dimensional analysis is a powerful tool used in science and engineering to understand and manipulate physical quantities.

It involves examining the dimensions or units of various quantities involved in a problem and using their relationships to derive new equations or convert between different units.

The process of dimensional analysis starts by identifying the relevant quantities involved in a problem and expressing them in terms of their base units (such as meters, seconds, kilograms, etc.).

Then, the dimensions or units of these quantities are compared and manipulated using algebraic operations such as multiplication, division, and cancellation.

The justification for using dimensional analysis lies in the principle of dimensional homogeneity. According to this principle, any valid equation must have the same dimensions on both sides.

By carefully considering the units, dimensional analysis allows us to check the consistency of equations, identify missing terms, derive conversion factors, or solve for unknown quantities.

Dimensional analysis is particularly useful in verifying equations, checking the correctness of derived formulas, and performing unit conversions.

It helps ensure that the mathematical relationships used to describe physical phenomena are consistent with the underlying physical principles and laws.

Additionally, it provides a systematic approach to solving problems and ensures that the final results have the correct dimensions and units, which is crucial for accurate and meaningful interpretation of scientific data.

Answer: We know that the frequency of the recessive allele (q) is 0.33, because 33 out of 100 organisms have short legs, which means that they must be homozygous recessive (q).

Let's assume that the frequency of the dominant allele (p) is x. We can calculate the frequency of the homozygous dominant (pp) individuals as x^2, and the frequency of the heterozygous (pq) individuals as 2x(1-x), using the Hardy-Weinberg equation:

p^2 + 2pq + q^2 = 1

Substituting q=0.33 and simplifying, we get:

x^2 + 2x(1-x)(0.33) + 0.33^2 = 1

Solving for x, we get:

x = 0.67

Therefore, the frequency of the dominant allele (p) is 0.67.

The study mentioned in the question found a correlation between the Zika virus and polluted bodies of water in Brazil. This highlights the importance of monitoring and addressing pollution levels in bodies of water to protect public health.

Public health officials must consider the impact of pollution on the spread of diseases such as Zika, as it can pose a hazardous threat, particularly to pregnant women.

The study's finding of an average chemical waste of 185 g per mile with a standard deviation of 10.58 g in heavily affected areas emphasizes the significance of addressing the polluted water sources to minimize the risk of disease spread. The degrees of freedom for this study would be 19.

Constructing a 95% confidence interval, we are 95% confident that the mean chemical waste of bodies of water for all areas where the Zika virus was overly active is between 231.577 and 246.423 g per mile. As for the margin of error, it would decrease if the sample size increased, as the larger sample size would provide a more accurate representation of the population's chemical waste. The confidence interval interpretation is a. We are 95% confident that the mean chemical waste of bodies of water for all areas where the Zika virus was overly active is between 231.577 and 246.423 g per mile. This means that we can reasonably assume that the average chemical waste in the bodies of water of these areas falls within this range with 95% confidence.

Answer: The option that is NOT true is:

C. Its primary fuel is fat.

Explanation:

Anaerobic metabolism does not primarily rely on fat as its fuel source.

The correct answer is Option (c)

Option (c) Its primary fuel is fat, which is NOT true of anaerobic metabolism.

Let's delve into the topic by breaking down the words anaerobic, which gives us an-aerobic.

Aerobic refers to anything, which involves the presence of air, or more specifically oxygen. Thus any aerobic activity would involve the presence and usage of oxygen for its necessary functions.

Anaerobic would thus mean any activity which doesn't require the presence of oxygen.

Anaerobic metabolism defines the process by which cells, without the presence of oxygen, produce energy for their work. When the supply of oxygen is limited, cells opt for this alternative pathway to produce energy to keep themselves running.

Here, the breakdown of glucose occurs even in limited oxygen to give us ATPs (Adenosine Triphosphate), the energy currency of the cell.

Coming back to the question, we go through the options one by one.

During high-intensity activities like sprinting or heavy exercise, your lungs don't work fast enough to provide the body with enough air. Thus the glucose gets decomposed without the presence of oxygen to give the body the energy it needs through anaerobic respiration.

Thus, option A is correct.

Anaerobic respiration or metabolism occurs in the fluid part of the cell known as the cytosol, due to the availability of a suitable environment for chemical reactions.

Thus option B is correct.

Anaerobic metabolism doesn't require oxygen, as discussed before.

Thus option D is correct.

But, the primary source of fuel for running anaerobic chemical reactions is not fat, but glucose which breaks down to give ATP.

Thus, option C is incorrect.

Thus, the answer to the question is option C.
