Answer:

The greenhouse effect is a natural process which increases the temperature of the Earth.  The greenhouse effect is caused by the absorption by the surface of the Earth and re-absorption by the atmosphere of the greenhouse gases (CH₄, CO₂, NO, CFCs ) in the environment.

This is caused when solar radiation reaches Earth- some of the energy is absorbed by the land and water while the rest of the energy is reflected back into space. Now the absorbed heat radiate from earths surface is trapped by the greenhouse gases in the atmosphere which causes the warming of the Earth. But due to the increase in greenhouse gases extra heat is absorbed  which leads to Global warming.

Answer:

False!

Explanation:

Edge

Stem

1. Grows upward show negative gravitrotropism

2. Stems don't absorb water and nutrients

3.Stems have trichomes

Roots

1 show positive gravitrotropism

2 absorb water and Minerals

3 bears root hairs

Roots are the underground part of the plant, and the main function is the absorption of water and minerals from the soil, conduction, storage of reserve foods and mainly in the anchorage of the plant. The chief distinction from the stems is the lacking of buds and leaf scars, but have root cap and branches that originate from internal tissues than from buds. And Stems are the part of the plant, that possesses buds, leaves and roots at its basal ends. The primary function of the stem supports the leaves and to transport minerals and water to the leaves, where it proceeded to convert into useful products by the process of photosynthesis, and then further these are transported to other parts of the plants including roots.

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.

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."

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.

Theoretically, the genetic code is universal. This means that the same codon "means" the same amino acid in all organisms. For example, in both humans and bacteria, a codon made of three thymine DNA-letters will code for an amino acid called Phenylalanine. There are about twenty amino acids, and about 64 codons.

Theoretically, the genetic code is universal. This means that the same codon "means" the same amino acid in all organisms.

For example, in both humans and bacteria, a codon made of three thymine DNA-letters will code for an amino acid called Phenylalanine.

A codon is found on the coding strand of double-stranded DNA and in the (single-stranded) mRNA.

The anticodon is found on the tRNA and is the part that base-pairs with the codon (on the mRNA) in order to bring the appropriate amino acid to the ribosome to be added to the growing peptide chain.

The answer would be C

Explanation: The coati eats a variety of different fruits, nuts and seeds, along with insects, birds eggs, rodents and small reptiles such as lizards and snakes.

The organism coati in this food web is an omnivore. Thus, option C is correct.

A food web is defined as the natural interconnection of food chains and is a graphical representation of what-eats in an ecological community. Food web is also known as consumer-resource system.

A food web consists of many food chains while a food chain follows only one path as animals find food. For example, Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. Thi shows the many different pathways that plants and animals are connected.

In this, the lower trophic level organisms have more energy than the upper trophic level because only 10% of the energy flows from one trophic level to the next. In the above case, beetles have the highest energy compared to other organisms.

Thus, Beetle in the food web below is likely to store the most energy. So, the correct option is (C).

Hello there!

This is a great question to be asking. Luckily, I have some information to tell you out so you can understand why people feel shy.

So when a person feels shy, their brain is interpreting a certain situation as a threat so say a person was talking up on a stage in front of others, their brain interprets talking no in front of a whole group of people as a threat. Usually people who are shy try to avoid any situations they can in front of a huge crowd or try to avoid eye contact. Also around 22% of people that are shy isn’t because their parents were.

Answer: Density -dependent factors.

Explanation:Density is defined as the mass of an object divided by its volume. Density can be used as a conversion factor between mass and volume.

Density-dependent factors are population control elements whose effects increase with population size, such as food scarcity and disease spread. Density-independent factors affect populations regardless of size, like natural disasters. Conservation biologists study these to manage populations sustainably.

Population control factors whose effects increase as the size of the population increases are known as density-dependent factors. These factors include competition for resources like food and space, predation, disease, and stress from overcrowding, which can all lead to higher mortality rates or lower birth rates as the population density rises. In contrast, density-independent factors affect populations regardless of their size and include events such as natural disasters or climate changes.

The effect of density-dependent factors is more pronounced in larger populations; as the population grows, these factors can serve as limiting elements to slow down or decrease the population size. For example, with the human population's continuous growth, increased competition for finite resources such as food, clean water, and livable space becomes more significant. Such scarcity can result in social issues like malnourishment, spread of infectious diseases, and conflict.

Understanding these factors is crucial for conservation biologists and wildlife managers to prevent extinction or overpopulation and to manage population growth sustainably. Particularly for humans, other considerations like migration, public health advancements, and changes in lifestyle due to technological developments also play significant roles in population dynamics.

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.

Answer: Symbiotic Relationship

Both fig trees and fig wasps are important for each others survival.

Explanation: The fig provides a joke for the wasps and the wasps provide pollen that the fig needs for  the fruit to ripen.

It basically begins when a female fig wasp enters the fig and lays eggs ,they pollinate the fig with pollen that they had collected in their pouches after mating ,when the wasp enters the fig its wings and parts of antennae may get broken because of the small opening in the fruit ,the wasp completes it's task and never leave the fruit after.

Fig trees and fig wasps have a mutualistic symbiotic relationship, where both species benefit from the interaction, with the wasps pollinating the trees while also laying their eggs, continuing their lifecycle.

Figs and fig wasps engage in a form of symbiotic relationship known as mutualism. In this relationship, both the fig tree and the fig wasp benefit from their interaction. The female fig wasp enters the syconium, or the inside-out inflorescence of the fig, where her wings are torn off, and she deposits her eggs. Through this process, she also inadvertently pollinates the fig's flowers using the pollen she carries from another fig tree. This results in the production of seeds for the fig tree and creates a nursery for the next generation of wasps. Eventually, the fig wasp offspring will hatch, with females collecting pollen before leaving to find a new fig to continue the cycle.

The relationship between figs and fig wasps is intricate and vital for the survival of both species. While some flowers are pollinated and develop into fig fruit, others serve as a development ground for new fig wasps. It is a highly specialized form of mutualism, with each species being indispensable to the other's lifecycle.

To contrast this relationship with another type, the text describes the southern masked-weaver bird nesting in a tree as commensalism, where the bird benefits and the tree is neither harmed nor benefited. This illustrates the diversity of species interactions in nature, ranging from mutualistic to commensal relationships.
