a. The Great Smoky Mountains National Park: Nonexcludable and rivalrous. Free rider problem likely.

b. Luetta Moore Park playground: Nonexcludable. No free rider problem.

c. National defense: Nonexcludable and nonrivalrous. Free rider problem exists.

d. Subway train: Nonexcludable. Free rider problem possible during peak hours.

a. The Great Smoky Mountains National Park: It is nonexcludable because it is difficult to prevent individuals from accessing the park. However, it is rivalrous as the park's resources, such as campsites or parking spaces, can be depleted. Both nonexcludability and rivalry suggest that the park is both nonexcludable and rivalrous. The free rider problem may occur since people can enjoy the benefits of the park without paying for its maintenance or preservation.

b. Playground at Luetta Moore Park: The playground is nonexcludable since it is difficult to prevent people from using it. However, it is nonrival as one person's use does not diminish the usability of the playground for others. Therefore, it is only nonexcludable. The free rider problem may not apply here since the use of the playground does not impose costs on others.

c. National defense: National defense is both nonexcludable and nonrival. It is nonexcludable because it is challenging to exclude individuals from benefiting from defense. It is nonrival because the defense provided to one person does not diminish the defense available to others. Both characteristics make national defense both nonexcludable and nonrival. The free rider problem is prevalent in national defense since individuals can benefit from defense without incurring the costs associated with it.

d. Subway train: A subway train is nonexcludable since it is difficult to prevent individuals from using it. However, it can be rivalrous during peak hours when overcrowding may limit the available space. Therefore, a subway train is only nonexcludable. The free rider problem may not be significant here as long as there are no capacity constraints or overcrowding issues.

Answer:

Explanation:

The frequency of heterozygous individuals can be calculated using the Hardy-Weinberg equation:

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

where p is the frequency of one allele (Z in this case) and q is the frequency of the other allele (z).

Given that the Z allele frequency is 89%, we can calculate q as:

q = 1 - p

q = 1 - 0.89

q = 0.11

Using this value for q and the given value for p, we can calculate the frequency of heterozygous individuals as:

2pq = 2(0.89)(0.11) = 0.196

So, the frequency of heterozygous (Zz) individuals in the population is 0.196 or 19.6%.

Chylomicrons are a type of lipoprotein synthesized in intestinal epithelial cells that distribute dietary fatty acids to cells.

Chylomicrons are indeed a type of lipoprotein. Lipoproteins are complex molecules composed of lipids (such as triglycerides and cholesterol) and proteins. They play a crucial role in transporting lipids through the bloodstream.

Chylomicrons are specifically synthesized in the intestinal epithelial cells of the small intestine. After a meal, when dietary fats are absorbed, the intestinal cells package these fats into chylomicrons. The chylomicrons contain primarily triglycerides, along with smaller amounts of cholesterol and other lipids.

Once formed, chylomicrons are released into the lymphatic system and eventually enter the bloodstream. Their primary function is to distribute dietary fatty acids and other lipids to various cells in the body. These fatty acids are essential for energy production and various metabolic processes.

As chylomicrons travel through the bloodstream, they interact with different enzymes, such as lipoprotein lipase, which breaks down triglycerides within the chylomicrons, releasing free fatty acids that can be taken up by cells. Chylomicron remnants, which are the remnants of chylomicrons after the release of fatty acids, are eventually cleared from the bloodstream by the liver.

In conclusion, chylomicrons are synthesized in intestinal epithelial cells, function as a type of lipoprotein, and play a vital role in distributing dietary fatty acids to cells throughout the body.

Answer:

D. both B and C

Explanation:

The control group is not to be altered as to have true results for comparison/differentiation.

Answer:

In photosynthesis, plants use sunlight, water, and carbon dioxide to create their own food and oxygen. The sunlight shines on the leaves of the plant, providing energy for the process. At the same time, the plant takes in water from its roots and carbon dioxide from the air. This energy from sunlight helps the plant combine water and carbon dioxide to create sugars, which act like food for the plant. In the process of making these sugars, the plant also produces oxygen, which it releases into the air. So, you can think of photosynthesis like a recipe: Sunlight, water, and carbon dioxide are mixed together to make sugars and oxygen. In terms of energy, the plant is transforming the light energy from the sun into chemical energy in the form of sugars.

Answer:

Photosynthesis is when plants use sunlight to make food. They take in water and carbon dioxide and turn them into sugars and oxygen. The plant uses the sunlight to make the sugars, and the oxygen is let out into the air. The equation for photosynthesis is: sunlight + water + carbon dioxide → sugars + oxygen. The sunlight changes into chemical energy during this process.

Explanation:

An old biological notion from the 19th century is called blending inheritance. According to the hypothesis, a kid receives a trait by averaging the values of its parents for that trait.

As an illustration, pink-flowered children might result from breeding a red flower variation with a white variant of the same species. Inheritance was blended according to Charles Darwin's idea of inheritance via pangenesis, which included contributions to egg or sperm from every organ of the body.

Fleeming Jenkin attacked Darwin's theory of natural selection because of his dependence on this mechanism, arguing that blending inheritance would average out any unexpected advantageous property before selection had a chance to work.

The widespread acceptance of particulate inheritance led to the rejection of blending inheritance.

The ability of certain lizards to lose their tail if attacked by a predator is an example of a protective function exhibited by physical characteristics, which are commonly referred to as adaptations.

Physical characteristics that aid organisms in their survival are called adaptations. These adaptations can be structural, physiological, or behavioral in nature. In the case of certain lizards, their ability to shed their tail when attacked by a predator is a defensive adaptation that helps them escape from potential harm.

1. Adaptations: Adaptations are traits or features that have evolved in organisms to enhance their chances of survival and reproduction. These can include anatomical structures, physiological processes, or behavioral patterns.

2. Defensive Adaptations: Defensive adaptations are specifically geared towards protecting an organism from harm. In the case of lizards, the ability to shed their tail, a behavior known as autotomy, is a defensive adaptation.

3. Autotomy: Autotomy is the self-amputation or shedding of a body part by an organism. Lizards, such as certain species of geckos or skinks, have developed the ability to voluntarily shed their tail when under attack. The detached tail continues to move, distracting the predator and allowing the lizard to escape.

4. Protective Function: The ability to lose the tail serves a protective function by allowing the lizard to survive encounters with predators. By sacrificing their tail, lizards can increase their chances of survival by diverting the predator's attention and facilitating their escape.

In summary, the physical characteristic exhibited by certain lizards, where they can lose their tail if attacked by a predator, is an adaptation that serves a protective function. This ability, known as autotomy, enhances their chances of survival by enabling them to escape from potential predators.

The organ responsible for storing bile is the gallbladder. So, the correct choice is Gallbladder.

The gallbladder, located beneath the liver, is the organ responsible for storing bile. Bile is a greenish-yellow fluid that aids in the digestion and absorption of fats.

It is produced by the liver and then transported to the gallbladder for storage. When we consume a meal containing fats, the gallbladder contracts and releases stored bile into the small intestine through the bile ducts. Bile helps in emulsifying fats, breaking them down into smaller droplets, which increases the surface area for enzymes to act upon. This process enhances the absorption of fats and fat-soluble vitamins in the small intestine.

The storage and controlled release of bile by the gallbladder ensure that an adequate amount of bile is available for the digestion and absorption of fats whenever required.

The option that is true for both the greenhouse effect and acid rain is:

D. Both global warming and acid rain can release acid into the water.

The greenhouse effect refers to the process by which certain gases in the Earth's atmosphere, such as carbon dioxide (CO2) and methane (CH4), trap heat and contribute to the warming of the planet. While the greenhouse effect does not directly release acid into the water, it does contribute to climate change, which can indirectly impact aquatic ecosystems. Rising temperatures caused by the greenhouse effect can affect the pH levels of water bodies, potentially leading to changes in acidity.

On the other hand, acid rain is caused by the release of pollutants, primarily sulfur dioxide (SO2) and nitrogen oxides (NOx), into the atmosphere from human activities like burning fossil fuels. These pollutants can undergo chemical reactions in the atmosphere and be deposited in the form of acid rain. Acid rain can harm aquatic environments by lowering the pH of water bodies and making them more acidic, which can have detrimental effects on aquatic life.

The option D accurately describes the commonality between the greenhouse effect and acid rain, as both can contribute to the release of acid into water bodies, albeit through different mechanisms.

Darwin's concept of natural selection encompasses the idea of "survival of the fittest," where individuals with advantageous traits are more likely to survive and reproduce, leading to the accumulation of beneficial traits in a population over time.

Charles Darwin referred to the concept of "survival of the fittest" as a key principle in his theory of evolution. This concept, also known as natural selection, describes the reproductive advantage that individuals with favorable traits have over those without these traits in adapting to their environment. However, it is important to note that the actual phrase "survival of the fittest" was coined by Herbert Spencer, not Darwin himself.

Darwin's term for this concept was "natural selection," which he described as the process by which certain heritable traits become more common in a population over successive generations. According to Darwin, individuals with advantageous traits are more likely to survive, reproduce, and pass on their genes to their offspring. These traits can include physical characteristics, behavioral patterns, or physiological adaptations that enhance an organism's ability to survive and reproduce in its specific environment.

Darwin emphasized that natural selection acts on the variation present within a population, allowing those individuals with beneficial traits to have a higher chance of surviving and producing offspring. Over time, this leads to the gradual accumulation of favorable traits in a population, resulting in adaptation to the environment.

It is important to understand that "survival of the fittest" does not imply that only the strongest or most powerful individuals survive. Instead, it refers to the reproductive success of individuals who possess traits that increase their fitness in relation to their environment. Fitness is defined by an organism's ability to survive, reproduce, and pass on its genetic information to future generations.

When the cell outgrows the cell membrane it will lead to the rupture of the membrane which would cause the cell death of the same.

All cells are covered by an outer membrane, called the plasma membrane, which separates them from other cells and from the surrounding environment with which they exchange matter and energy.

This exchange is highly regulated and selective, in this way the plasma membrane must act not only as a cell border but also as a selective barrier.

Cells must take up food and other materials through their plasma membrane and must remove waste products quickly before they accumulate to levels toxic to cell survival.

When the cell outgrows the cell membrane, it breaks, the components go outside and the cell can no longer maintain its functions.

That is, such disturbance would make it impossible to maintain homeostasis, it would not be possible to eliminate water and ions, which accumulate inside the cell and cause the rapid loss of the integrity of the plasma membrane.

Cellular organelles and the entire cell swell until they are lysed and their contents are released to the extracellular environment.

The release of the cytoplasmic content and lysosomal enzymes causes considerable damage that spreads into the surrounding tissue, giving rise to an intense inflammatory response that leads to the death of cells in the environment.
