Answer:
possible differences resulting from using two different breeds of dog
Explanation:
The question above presents a scientific experiment carried out by students Pablo and Johanna from the biology course. In this experiment, they both compare the results of different diets on their dogs. Up to this point, the experiment was being established correctly, since the variables independent (the composition of the dogs' diet) and dependent (the influence of the diet on the dog) were defined. However, these students made a mistake in using dogs of different breeds.
In an experiment, everything must be very controlled and the treatments must be exactly the same. In the above case, the dogs are the treatments and the fact that they belong to different breeds, means that the results of the experiments can present significant differences, not providing a correct conclusion of the experiment.
Criminal evidence is any physical or verbal evidence presented in court to prove a specific crime. Evidence can take different forms and can be used by the accused to prove innocence. Admissible evidence, moreover, is the use of testimony (oral or written such as affidavit), exhibits (physical objects), documentary material or demonstrative evidence ( in the form of representation of an object including photos, x-rays, videotapes, movies, sound recordings, diagrams, forensic animation, maps, drawings, graphs, animation, simulations or models). All are presented before a judge or jury to prove a point or element in a case. In the choices above, six of them can qualify as individual evidence except numbers 3. Number 8, however, is questionable since it has incomplete description as to where and how is the paint was chipped.
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades, or even millions of years after a mass extinction
Answer:
The plasma membrane is made up by a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. Only relatively small, non- polar materials can easily move through the lipid bilayer of the plasma membrane.
