Answer:
Observations; control.
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
On the other hand, a control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
<em>This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.</em>
1. Every framework has their doing in arranging our body capacities. Regardless of whether it's the heart drawing blood through our body and lungs boosting oxygen and discharge carbon dioxide. Endocrine gives the correspondence through hormones; secrete their hormones directly into the bloodstream and uses blood vessels as information channels. It stimulates sebaceous glands whereas the sex hormones affect the distribution of subcutaneous fat. In addition, the endocrine system regulates metabolism, growth and development of tissues, and sexual functions. The endocrine and integumentary systems correlate with the sense organs, which react to heat, cold, vibration, texture, and pressure. When such senses are produced by the sense organs they react to the senses and send the information to the endocrine system and therefore hormones are released which causes the mood swings according to the situation. For example, it reacts to the body with pleasure or discomfort related to the senses.
2. Atomic solution and radiology bring the procedures which analyze and regard maladies by utilizing radiopharmaceuticals as the pictures of body organs or envision certain infections. This involves radiations which are used to diagnose, treat and prevent certain diseases. In the present era, these procedures are the best and hence the most effective life-saving techniques. They are safe and painless as compared to other surgical treatments involving operations. They don’t even require anesthesia. Both of these techniques are used in diagnosing a disease and monitoring the course of an illness. They are then used for the treatment of any disease as well. Diseases such as cancer or heart disease are therefore treated by radiation technology.<span>

The disadvantages of the pyramid of productivity as a representation: The rate of biomass production of an organism is required, which involves measuring growth and reproduction through time. There is still the difficulty of assigning the organisms to a specific trophic level.
The fish is the limiting factor because its population <u>determines the survival and availability of the grizzly bears.</u>
A limiting factor is resources(biotic or abiotic) that affects or determine the availabity and growth of an organism or group of an organism within an ecosystem.
The more fish it takes, the more the liver produces urea, and kidney tubules makes use of the urea in it tubules for urine formation in the loop of Henle. The urine formation and loss, leads to intake of water and the sequence continues.
This is an example of a biological limiting factor because the bear predate on the fish for survival and population.
If the population of the fish drops,( <u>the limiting facto</u>r) the bear drinks less water based on above, and therefore <u>disruptions of the ecosystem</u>.
