Multidisciplinarity draws on knowledge from different disciplines but stays within their boundaries. Interdisciplinarity analyzes, synthesizes and harmonizes links between disciplines into a coordinated and coherent whole.

Final answer:

The difference between interdisciplinary and multidisciplinary approaches lies in how they integrate different disciplines. Interdisciplinary studies blend methods from various fields to create new understandings, while multidisciplinary studies involve collaboration without integrating disciplines.

Explanation:

The primary difference between interdisciplinary and multidisciplinary approaches is how various disciplinary perspectives are integrated. Interdisciplinary studies involve the blending of concepts, methodologies, and tools from different disciplines to create a new understanding or solve problems with a holistic view. For instance, the interdisciplinary nature of ethnomusicology speaks to diverse approaches to studying the anthropology of music, expressing a wide array of perspectives and experiences.

In contrast, multidisciplinary studies involve several disciplines working together but maintaining their separate identities; each provides its perspective to the subject at hand without necessarily integrating the analyses. A multidisciplinary approach may have a team of experts from various fields such as economics, sociology, and engineering assess a complex problem, with each expert considering the issue from their professional vantage point.

Interdisciplinary approaches are increasingly essential in understanding complex, real-world issues such as human-animal relationships, which can involve biology, psychology, sociology, and ethics. These approaches enrich our understanding by creating connections across disciplines that might not be considered when looking through the narrow lens of a single specialty. The training in anthropological holism reflects this interdisciplinary approach by preparing researchers to perceive and analyze the interplay between biology and culture, influencing each other.

The Moon is the natural satellite of Earth. Its revolution lasts 27.322 days, while its rotation around its axis lasts 27 days. From the Earth's perspective, the Moon seems to have different phases, where it appears as fully lighted, partially lighted, or totally dark. What the Moon appears to be from the Earth depends on how the Earth, Moon, and Sun are aligned in relation to each other. If the Earth is between the Sun and the Moon, the Moon is full, with the reason being that the Sun is lighting up the side that is facing the Earth. If the Moon is between the Earth and Sun, then the Moon can not be seen, it is totally dark, and that is because the side that is facing the Earth is not lighted by the Sun at all. If the Moon is positioned sideways, not being in a straight line with the Earth and Sun, then it appears to be partially lighted, and that is the side that can be seen from Earth that is lighted by the Sun.

Answer:

Urban ecosystem has its own niche compared to nonhuman life. as humans we have adapted to our new technologies and inventions that animals and plants don't have.

Explanation:

Non-human life in urban ecosystems differs from non-human life in undeveloped forest ecosystems in terms of reduced biodiversity, presence of species adapted to urban environments, and limited access to natural resources.

Non-human life in an urban ecosystem differs from non-human life in an undeveloped forest ecosystem in several ways. First, urban ecosystems are heavily influenced by human activities and infrastructure, such as buildings, roads, and pollution. This can lead to a reduction in biodiversity and the loss of natural habitats for many species. In contrast, undeveloped forest ecosystems have a higher biodiversity and provide more suitable habitats for a wider range of species. Second, urban ecosystems often have a higher density of non-human life that is adapted to urban environments, such as pigeons, rats, and insects. These species have successfully adapted to living in close proximity to humans and taking advantage of the resources available in urban areas. In undeveloped forest ecosystems, the non-human life is typically more diverse and includes a wider range of species adapted to the natural environment, such as birds, mammals, and insects. Lastly, urban ecosystems often have less natural resources and limited access to food and water sources, which can impact the survival and distribution of non-human life. Undeveloped forest ecosystems, on the other hand, typically have abundant natural resources, including food and water sources, which support a larger and more diverse array of non-human life.

Final answer:

The increase in the number of predators in an ecosystem is likely due to an increase in the population of prey it feeds on, as they are limiting factors on each other's growth in a cyclic relationship.

Explanation:

The question addresses the dynamics of predator-prey relationships within an ecosystem. An increase in the number of predators can potentially be caused by b. An increase in the population of prey it feeds on. This is supported by the concept that predator and prey populations are limiting factors on each other's growth. As the prey population increases, there is more food available for predators, which can lead to an increase in the predator population. This relationship is cyclic and can be observed as a mirror image pattern where the rise in prey numbers results in a rise in predator numbers, followed by a downturn in prey, subsequently leading to a downturn in predators, repeating this cycle indefinitely.

"The correct option is b. An increase in the population of prey it feeds on is a possible cause for the growth.

To understand the possible cause for the growth in the number of predators in an ecosystem, let's consider the ecological dynamics:

a. A decrease in the population of prey it feeds on: If the prey population decreases, predators would likely struggle to find food, leading to a decrease in their population due to starvation or the need to migrate to other areas with more prey. This option is incorrect because it would lead to a decrease, not an increase, in predator numbers.

b. An increase in the population of prey it feeds on: When there is an abundance of prey, predators have more food available, which can lead to increased survival rates of predator offspring and potentially immigration of additional predators to the area. This surplus of food can support a larger predator population, causing it to grow. This option is correct as it provides a logical explanation for the observed increase in predator numbers.

c. A decrease in the biodiversity of the ecosystem: A decrease in biodiversity could lead to a loss of species that compete with the predators for food or that prey on the predators themselves. However, a direct decrease in biodiversity does not necessarily lead to an increase in predator numbers. This option is not as directly related to predator population growth as the availability of prey is.

d. An increase in the number of predators that feed on it: If there are more predators feeding on the original predators, this would typically lead to increased mortality among the original predators, not an increase in their population. This option is incorrect because it suggests a top-down control on the predator population, which would likely result in a decrease in their numbers.

Therefore, the most plausible explanation for the increase in the number of predators in an ecosystem is an increase in the population of prey it feeds on, which provides more resources to support a larger predator population."

Answer:

Increased greenhouse effect

Explanation:

The methane is a gas that falls in the category of ''greenhouse gases''. It is actually the most effective ''greenhouse gas'', much more effective than the CO2, though it has to be mentioned that that is on the short run. Basically, the methane has a property that enables it to trap the heat into the atmosphere. When the heat is reflected from the surface of the Earth it moves back toward the space, but the methane manages to trap big portion of that heat, resulting in an increased greenhouse effect across the globe.

Answer:

Because the surrounding doesn't go exactly go into the body.

It has to go through the clothes first

Final answer:

Clothing lowers body temperature by reducing heat transfer due to its insulating properties, slowing down both conduction and convection. Clothing also has a lower emissivity, meaning it radiates less heat than skin.

Explanation:

Adding clothing helps to lower body temperature by reducing heat transfer to the environment. This occurs because clothes act as insulators that slow down both conduction and convection. Conduction is when heat is transferred through materials, while convection is the transfer of heat by the movement of fluids, like air. Wearing clothing, particularly thicker or numerous layers, creates an insulating barrier that traps heat close to the body, preventing it from being easily transferred to the cooler surrounding air.

Clothing also exhibits a lower emissivity than skin, particularly if it's light-colored, which means that it doesn't radiate as much heat as bare skin would. This is significant because air convection naturally removes heat from our body, and by wearing clothing, we lessen the rate of heat lost through these mechanisms. Proper clothing allows for body temperature regulation, ensuring that our body remains at a comfortable and healthy temperature by balancing between the heat produced by metabolic activity and the heat lost to the environment.

Answer:

the Hardy-Weinberg assumptions are:  no mutation, random mating, no gene flow, infinite population size, and no selection.

When a population is in Hardy-Weinberg equilibrium?  Evolution will not occur

***The Hardy-Weinberg equilibrium can be disturbed by a number of forces, including mutations, natural selection, nonrandom mating, genetic drift, and gene flow***

Explanation:

In biology, the Hardy-Weinberg principle assumes a large population size, isolated gene pool, random mating, no mutations or natural selection, with genotype and allele frequencies remaining constant at equilibrium. Allele frequencies are used to calculate genotype frequencies; for instance, if the frequency of homozygous recessive (aa) is 0.04, the frequency of the recessive allele (q) is 0.2 and of the dominant allele (p) is 0.8, leading to a heterozygote (Aa) frequency of 0.32.

Assumptions for the Hardy-Weinberg Equation

The Hardy-Weinberg principle is grounded in several key assumptions to predict the genetic variation within a population. First, the population must be large to minimize random genetic drift. Second, there should be no gene flow, meaning the population is effectively isolated with no migration in or out. Furthermore, mating must be random to ensure all alleles are equally likely to be passed on to the next generation. Additionally, mutations should not occur so that allele frequencies remain constant. Finally, there should be no natural selection, which implies that all individuals contribute equally to the gene pool.

Hardy-Weinberg Equilibrium

When a population is in Hardy-Weinberg equilibrium, the allele and genotype frequencies remain constant from one generation to the next, in the absence of evolutionary pressures. A population in equilibrium must meet the assumptions discussed above. In practice, it's unlikely for natural populations to remain in equilibrium due to factors like genetic mutations, natural selection, and non-random mating patterns.

Allele and Genotype Frequencies

An allele is a variant form of a gene. Genetic equilibrium suggests that the frequency of alleles in a population's gene pool remains constant over time in the absence of evolutionary forces. The genotype frequencies, which are expressions of allele combinations such as AA, Aa, and aa in a population, can be projected based on allele frequencies (p for dominant allele A and q for recessive allele a) if Hardy-Weinberg conditions are met.

Example Calculation

If we assume that the frequency of the homozygous recessive genotype (aa) is 0.04 (4%), we can find the square root of this frequency to determine q, which is the frequency of allele a. Thus, q equals 0.2. Because p + q = 1, we find that p, the frequency of allele A, equals 0.8. To calculate the frequency of the heterozygous genotype (Aa), we use the equation 2pq, which equals 2(0.8)(0.2) or 0.32 (32%).
