Answer:- These organic nutrients move up through the food chain. However, when death occurs, decomposition returns the nutrients to the earth.

Answer:- Saccharomyces are EUKARYOTES. Every eukaryotic organisms possesses a membrane bond nucleus. Nucleus is surrounded by inner membrane (Non-ER) & outer membrane (ER). It is a non-motile organism. It reproduces by budding. It can be grow as haploid (n) or diploid (2n).

Answer:- As described by Darwin, evolution occurs by a process called natural selection. In natural selection, some members of a species, being better adapted or suited to their environment, produce more offspring than others, so they pass "advantageous traits" to their offspring.

Answer:- the dependent variable goes on the y-axis while the independent variable goes on the x-axis

Answer:- Mice and rats have long served as the preferred species for biomedical research animal models due to their anatomical, physiological, and genetic similarity to humans. Advantages of rodents include their small size, ease of maintenance, short life cycle, and abundant genetic resources.

Answer:- Mice are the most commonly used animal model for studying human disease, and for many good reasons: Mice are biologically very similar to humans and get many of the same diseases, for the same genetic reasons. Mice can be genetically manipulated to mimic virtually any human disease or condition.

Answer:- Scientists from a wide range of biomedical fields have gravitated to the mouse because of its close genetic and physiological similarities to humans, as well as the ease with which its genome can be manipulated and analyzed.

Answer:- The term “animal testing” refers to procedures performed on living animals for purposes of research into basic biology and diseases, assessing the effectiveness of new medicinal products, and testing the human health and/or environmental safety of consumer and industry products such as cosmetics, household cleaners, ...

Answer:- Mice are keystone species in almost every ecosystem. In forests, fields, and deserts, mice represent food to predators of all sizes. They link plants and predators in every terrestrial ecosystem. Weasels, foxes, coyotes, hawks, owls, skunks, shrews, bobcats, and bears all eat mice.

Answer:- The most important reason for using rats and mice in research is to model aspects of human physiology and function, most notably to advance our understanding of human diseases.

Answer:- Because of the similarity of the rat molar to humans, the rat is often used in which type of research studies? Because rats have a unique ability to adapt to new environments they are a good animal model for: behavioral research.

Answer:- The laboratory rat has made invaluable contributions to cardiovascular medicine, neural regeneration, wound healing, diabetes, transplantation, behavioural studies and space motion sickness research. Rats have also been widely used to test drug efficacy and safety.

Answer:- The benefits of animal models are that one can study the mechanisms of diseases as well as test new and emerging drugs for their therapeutic efficacy. Rheumatoid arthritis (RA) is one of the autoimmune disorders for which different animal models are available, and each and every model has its merits and demerits.

Answer:- When animal models are employed in the study of human disease, they are frequently selected because of their similarity to humans in terms of genetics, anatomy, and physiology. Also, animal models are often preferable for experimental disease research because of their unlimited supply and ease of manipulation.
