The relative energetic cost of the primary nitrogenous wastes generated by different animals varies depending on the type of animal and their specific physiological processes.

However, in general, the correct rank order from highest to lowest energetic cost is as follows: uric acid, ammonia, and urea. Animals that excrete uric acid, such as birds and reptiles, require the most energy to produce this waste due to its low solubility and the need for active transport to eliminate it. Ammonia excretion, which is common in aquatic animals, is energetically less expensive but requires a lot of water for dilution. Finally, urea excretion, which is used by mammals and some fish, is the least energetically costly as it is synthesized in the liver and eliminated via the kidneys in a concentrated form, requiring less water loss.

The actual size of the onion cells under microscope is 0.02 mm

Magnification = Image / Actual

Image= 20 mm

Actual= x mm

1000x = 20 mm/ x mm

Actual = 0.02mm

Magnification is the number of times a picture is magnified in comparison to the actual size of the thing. The overall magnification of a microscope is determined by the eyepieces and the objective lens. A biological microscope with 10x eyepieces and a 50x objective, for example, has a magnification of 500x. Hence, the actual size of the onion cells is 0.02 mm, when placed under a microscope with a 1000x magnification it image size now becomes 20 mm.

In a forest community, the shelf fungus and the slug live in a mutually beneficial relationship on the side of a decaying tree trunk.

The shelf fungus digests and absorbs materials from the tree, while the slug eats algae growing on the outside of the trunk. This is an example of commensalism, where one organism benefits while the other is unaffected. The shelf fungus benefits from the decaying tree trunk and does not compete with the slug for food since the slug feeds on the algae, which the fungus cannot use. Likewise, the slug benefits from the algae on the tree trunk and does not compete with the fungus since it feeds on a different resource. Therefore, the two organisms are able to coexist in the same habitat without any competition, and each fulfills a different role in the ecosystem.

1. The organelles observed by Alex are the nucleus, centrosome, and mitochondria.

2.It is a plant cell.

Eukaryotic cells are complex cells that make up the tissues and organs of living organisms, including humans, animals, plants, and fungi. These cells are characterized by having a distinct nucleus, which houses the cell's genetic material, in the form of DNA.

(i) Alex observed a tiny star-like body close to a large dense spherical body at the center of the cell. The large dense spherical body is most likely the nucleus, which is a characteristic organelle found in eukaryotic cells. The tiny star-like body close to the nucleus is likely the centrosome, which is also found in eukaryotic cells. Alex also observed many rod-shaped structures scattered inside the cell. These rod-shaped structures are likely mitochondria, which are also organelles found in eukaryotic cells responsible for energy production. Therefore, the organelles observed by Alex are the nucleus, centrosome, and mitochondria.

(ii) It is not possible to determine if the cell observed by Alex is a plant cell or an animal cell based solely on the information given. Both plant and animal cells contain a nucleus, centrosome, and mitochondria.

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 possibility that explains the presence of fossils of the same species in different regions is that the animals migrated. The correct answer is A.

Migration is a common phenomenon observed in various animal species. Animals move from one region to another in search of food, suitable habitats, or favorable environmental conditions.

This movement allows them to adapt to different environments and exploit available resources. As animals migrate, they can leave behind fossils in the regions they previously inhabited.

When animals belonging to the same species migrate to different regions, their populations become geographically separated.

Over time, the separated populations may undergo different evolutionary pressures, leading to the development of distinct traits and adaptations.

These changes can eventually result in the formation of different subspecies or even new species. Fossil evidence of the same species found in different regions supports the idea that migration played a role in the dispersal and distribution of these animals.

Therefore, the presence of fossils of the same species in different regions is indicative of past migration events and the subsequent divergence of populations. Therefore, the correct answer is A.

Leaves play an important role in excretion in plants. They are responsible for removing waste products, such as carbon dioxide and water, that are produced during photosynthesis and cellular respiration.

One of the main ways that leaves excrete waste products is through transpiration, which is the process of releasing water vapor from the leaves through small openings called stomata. This process not only helps to remove excess water from the plant, but it also helps to release waste gases such as carbon dioxide and oxygen that are produced during photosynthesis.

Leaves also excrete waste products through guttation, which is the release of water droplets from the leaves. This process helps to remove excess water that is not needed by the plant.

Additionally, leaves also excrete waste products in the form of excess minerals, which are not needed by the plant and are removed via root exudation.

In summary, leaves play a crucial role in excretion in plants by releasing waste products such as carbon dioxide, water, and excess minerals via transpiration, guttation, and root exudation.

The organelle that is represented by these models and is considered to have a double membrane is the mitochondria. Mitochondria are organelles that are responsible for energy production and storage in the cell.

Their double membrane consists of an outer membrane and an inner membrane. The outer membrane is permeable to most molecules, allowing them to enter or exit the mitochondria. The inner membrane, however, is much more selective and only allows certain molecules to pass through. It is also highly convoluted, creating numerous folds and crevices.

This increases the surface area of the inner membrane, which allows it to carry out its metabolic functions more efficiently. The double membrane of the mitochondria also plays an important role in controlling the cell's energy balance, as it is responsible for regulating the movement of metabolites, ions, and proteins between the mitochondria and other cellular components.

Answer:

mutualism

Explanation:

There is a mutual benefit in both parties.

The relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism, a type of symbiotic relationship in which both organisms benefit from the interaction.

In a mutualistic relationship, both organisms benefit from their interaction with each other. This is different from parasitic or commensal relationships, where one organism benefits at the expense of the other, or where one organism benefits while the other is neither helped nor harmed. In the case of the siboglinid tube worm and the symbiotic bacteria that live in its tissues, the tube worm benefits from the bacteria's ability to oxidize hydrogen sulfide or methane, which provides the worm with a source of energy and nutrients. This is important because the tube worm has no digestive tract of its own and cannot obtain food directly from the environment.

Hence, the relationship between the siboglinid tube worm and the symbiotic bacteria that live in its tissues is an example of mutualism.

Yes, the disease specialist's explanation is plausible based on what we know about evolution by natural selection. Let me break it down for you in simpler terms.

The disease specialist is suggesting that the tropical fungus mentioned by your colleague might be related to the fungal pathogen causing the illness at the hospital. They explain that even though the tropical fungus may have been brought to Vancouver Island some time ago, it might not have caused any illness until now. This could be because the tropical fungus was originally adapted to a different environment and couldn't infect people in the new environment of Vancouver Island.

Now, here's where evolution by natural selection comes into play. Over time, organisms can undergo changes in their traits and abilities through a process called natural selection. Mutations, which are changes in the genetic material of organisms, can happen randomly. If a mutation occurs in the tropical fungus that enables it to infect individuals in the Vancouver Island environment, it could be favored by natural selection.

For example, let's say that due to a mutation, the tropical fungus developed adaptations that allowed it to thrive in the new environment and infect people. These adaptations might include changes in its ability to penetrate human cells or evade the immune system. As a result, the fungus would become more successful at causing infections in the Vancouver Island population.

So, the disease specialist's explanation is plausible because it suggests that over time, through natural selection acting on mutations, the original tropical fungus could have evolved adaptations that made it capable of causing illness in the new environment of Vancouver Island.

Some plants have extraordinarily lengthy roots, which enable them to draw water from a great depth below the Earth's surface. For insects to visit and aid in pollination, other plants have flowers that are the ideal shape.

The thick stems and leaves of plants are reservoirs for water. Animals are deterred from ingesting plant material by the spines. Photosynthesis is carried out by green stems on some plants. To shade the plant and reflect light, hairs on the leaves or stems are helpful.

Loss of habitat, pollution, over-exploitation, invasive species and climate change are the five greatest dangers to biodiversity. Invasive species have been introduced as a result of increased trade and movement, whilst other risks are a direct result of resource consumption and population growth.

The term "biodiversity" describes the variety of life—both flora and fauna—found in a certain region or throughout the entire earth. The primary causes of biodiversity loss are habitat loss and fragmentation, Overexploitation, exotic species, and Pollution Poaching is the term for taking an animal without a license. For instance, tigers were murdered for their fur or skin, while elephants were killed for their tusks, etc. It falls under the category of overuse of natural resources. Natural ecosystems are being destroyed quickly for things like agriculture, building, dams, and other activities as a result of population growth and rising demand. Both of them are drastically diminishing biodiversity.
