A scientific argument is a method that researchers use to direct their work. In order to ultimately improve rational explanations and experimental designs, scientists point out flaws and limitations in other people's arguments. Evidence-based arguments is the term for this technique.

The aim of scientific reasoning is to assess the reliability and validity of methods and results. It would be appropriate to accept the scientific research if one could validate and demonstrate all of the points made. This part is structured around the four components of scientific argumentation

The method by which research, as a field, creates and greater integration, is through scientific debate. Other scientists assess and analyze the assertions, supporting evidence, and explanations of that evidence when scientists make arguments in favor of novel theories.

In this case, we need to separate events, on one hand, we have COVID-19 and on the other, we have climate change. Also, their repercussions and implications differ one from another. In the case of Climate change, we have that, there is an increase in global temperature making many sites warmer and changing ecosystems for wildlife, among these consequences we have extinctions, local and global, also there is a change in species distribution sometime are smaller other times there is displacement. Another consequence is the uncontrolled proliferation of other organisms, all these together mark a disequilibrium in populations, communities, ecosystems, and in the general biosphere. However life is dynamic so is changing all the time, that is to say, evolving, so we can see some early changes like columnar cacti that are changing from pollinators instead of bats, moths are taking their places as the distribution of species is changing.

In the case of COVID-19 is a very recent phenomenon that actually impacts a reduced group, humans, many of the problems generated are of social character more than biological, nonetheless when there is change as a society there is an indirect effect on the environment, for example, levels of air pollutants have diminished due to the prolonged quarantines. Other consequences can be mentioned at a physical level, it is known that viruses mutate, however, our own immune system has the same capacity, so the impact of coronavirus will be less as humans start to coevolve with the virus.

Now from a scientific approach, how these changes ans consequences are noticed? well, there is a number of different approaches inside the scientific method, nonetheless, there are certain key points that scientific studies must follow. The first and most important is the observation of the phenomenon, a hypothesis formulation, and the collection of information to prove or disprove the hypothesis, finally deductions and conclusions are obtained based on the observations and data found.

Answer:

The atom is a fundamental unit of matter that consists of a dense, central nucleus surrounded by a cloud of electrons. The nucleus is made up of protons and neutrons, while the electrons orbit the nucleus in a set of shells or energy levels. In the electrical current process, atoms play a key role in the movement of electrons through a conductor.

When an electrical current is applied to a conductor, the electrons within the atoms of the conductor are forced to move through the material. This movement of electrons is called an electric current. The movement of the electrons is caused by the difference in electrical potential between two points, which creates an electric field that acts on the electrons.

The movement of the electrons through the conductor is influenced by the structure of the atoms in the conductor. For example, a conductor with a high number of free electrons, such as copper, will allow the electrical current to flow more easily than a conductor with fewer free electrons, such as steel. The resistance of a conductor to the flow of an electrical current is known as electrical resistance, and it is influenced by the number of free electrons available to carry the current and the structure of the atoms in the conductor.

Overall, the atom plays a central role in the electrical current process, as the movement of the electrons within the atoms is what allows the electrical current to flow through a conductor.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

The sense of smell in tigers is highly developed and serves as a critical tool for survival. It helps them locate prey, establish territories, detect potential threats, and identify reproductive opportunities. The acute sense of smell in tigers enhances their hunting efficiency and contributes to their overall adaptation as top predators in their habitats

The sense of smell in tigers is particularly strong and plays a crucial role in their survival. Tigers have a highly developed olfactory system, equipped with specialized receptors in their nasal cavity that allow them to detect and discriminate various odors in their environment.

The sense of smell is essential for tigers when it comes to finding food. Tigers are carnivores and rely on hunting to sustain themselves. Their acute sense of smell helps them locate potential prey, even from a distance. Tigers can detect the scent of other animals, such as deer or wild boar, which enables them to track and stalk their prey effectively.

The olfactory system of tigers allows them to detect not only the presence of potential prey but also to gather information about the prey's location, health, and even reproductive status. They can identify the scent markings left by other tigers, which help them establish and defend their territories. Additionally, tigers can use their sense of smell to detect the presence of rival tigers or potential threats in their surroundings.

The ability to smell plays a vital role in a tiger's hunting strategy. Tigers often rely on ambushing their prey, and a keen sense of smell allows them to analyze the scent trails left by potential prey, determining their direction and estimating the distance to their target. This helps tigers plan their approach and execute precise and efficient hunting strategies, increasing their chances of a successful kill.

Moreover, a tiger's sense of smell is not only limited to locating prey but also plays a role in identifying potential mates. During the breeding season, female tigers release pheromones that indicate their receptiveness to mating. Male tigers can detect these scents and use them to locate and court females.
