Probably nothing, but it's not a good idea to let them. Caffeine (and any other stimulant) is best to be avoided with cats. Caffeine's L.D. 50 (the dosage that's lethal for 50% of test subjects) for cats is about 150 mg/kg. That's pretty characteristic of caffeine (it's the same with humans), but cats are pretty small, so a lethal dose of caffeine is also pretty small.
A student of radiography must study many subjects. Some of these subjects include anatomy and physiology, algebra, and microbiology. Students will also have to take technical classes to learn to operate the radiography equipment.

The term that applies to this part of the experiment is "exhaustion" or "failure." This refers to the point at which the subjects, in this case, the mice, can no longer sustain the required activity levels due to depletion of energy reserves, leading to a halt in their participation and ultimately resulting in death. This phenomenon can be indicative of the limits of endurance and the consequences of prolonged exertion without adequate recovery.
The term for studying subjects in their natural habitats is "field research" or "fieldwork." This type of research involves observing and collecting data in real-world settings rather than in a controlled laboratory environment.
The student should ensure that each group of test subjects is treated identically in all aspects except for the variable being tested (caffeine). This would involve administering different doses of caffeine to each group, monitoring the dogs' behavior and physical responses, and noting any differences observed among the groups. The student should adhere to ethical guidelines for animal testing and consult with a professional veterinarian for guidance.
all subjects receive treatment's
an experiment where the subjects know what is going on. they are not tricked or fooled with any tactics to increase validity such as placebos etc.
Scientists use repeated trials to ensure the reliability of their results by conducting the same experiment multiple times under the same conditions. For example, if testing a new drug, researchers might administer it to several groups of subjects and repeat the trials to confirm consistent effects. Replication involves other scientists independently conducting the same experiment to verify findings; for instance, if a study claims a certain treatment is effective, other labs will attempt to replicate the results to validate the initial claims. Both practices help minimize errors and biases, enhancing the credibility of scientific conclusions.
double blind method.Double-blind describes an especially stringent way of conducting an experiment, usually on human subjects, in an attempt to eliminate subjective bias on the part of both experimental subjects and the experimenters. In most cases, double-blind experiments are held to achieve a higher standard of scientific rigor.
science is a really fun subject, you get to experiment!
Before conducting an experiment, a scientist needs to review relevant literature to understand the existing knowledge and identify gaps their research could address. They should also examine the experimental design, including methodologies, controls, and variables, to ensure a robust approach. Additionally, reviewing safety protocols and ethical guidelines is crucial to ensure compliance and the well-being of subjects involved. Lastly, assessing the necessary equipment and materials is essential for proper planning and execution.
the control group
The matched subject because the experiment involves pairs which halves the df.
Because then the grouping is (technically) not random. In order for an experiment to yield proper results, the grouping must be random. If the researcher assigns subjects to groups in the order in which they arrive, then the randomness of the experiment is not present. cw: There are experiments on experiments that show that the first half of subjects are different from the second half of subjects. Why is another question. So you should randomize the allotment of subjects to treatments (groups).
