Evolutionary theory has become the central organizing principle of biological science. Could this scientific theory ever become
sveta [45]

The answer requires looking at the meaning of the words 'theory' and 'law'. The formal definition of a theory is that it is a comprehensive explanation of a observed phenomenon supported by a lot of evidence. Law is a fact that is bound to be true in nature, example Newton's second law. However, a theory is subjected to continuous refinements based on the several new findings that happen with time. These refinements make the theory appear incomplete. As with the theory of evolution, a lot of research work is being put to understand the complex phenomenon of genetic inheritance of traits of behaviour. Unless there are evidences from nature for all the aspects of evolution in theory, it'll remain a theory and not become a law.

Answer is A) Yes, if scientists decide that enough evidence supports the theory.

If a natural disaster caused all warbles to go extinct, why would the natural disaster not kill all living organisms?
likoan [24]

Answer:

Living organisms that are able to adapt to the environment (natural disaster) will increase in number while the ones such as warbles who can't adapt will die and go into extinction.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

Additionally, due to genetic variation within populations, some living organisms have a better chance of possessing good or beneficial traits being passed from the parent organism to her offsprings which enables them to survive a natural disaster.

Hence, if a natural disaster caused all warbles to go extinct, the natural disaster may not kill all living organisms due to natural selection.

TiliK225 [7]

Answer:

<em>The correct option is D)  How is the number of frogs in Massachusetts affected by pollution</em>

Explanation:

A scientific question can be described as a question which can be answered through the scientific method of research. Based on the scientific question, a hypothesis can be formulated. For example, for the option D, the hypothesis can be 'if the pollution increases, then the number of frogs decreases.' A hypothesis is a tentative statement which can be tested through experiments. Based on these experiments, results are formulated and conclusions are drawn. The question mentioned in option D can be answered through this method hence, it is the correct option.

If the pancreas fails to make ,"BLANK" it will inhibit the action of enzymes and affect chemical digestion. Also,"BLANK"  might
seropon [69]

The pancreatic juice is secreted by the pancreas. This pancreatic juice is secreted into the first part of the small intestine known as the duodenum. This pancreatic juice is rich in various enzymes that help in the digestion of various food components (carbohydrates, fats, and proteins). Besides being rich in enzymes, it is also rich in bicarbonate content. The bicarbonate works to neutralize the acidic chyme. This helps the enzymes to function and carry out digestion properly. If the pancreas fails to produce bicarbonate, then the function of enzymes will be altered, and the acidic chyme (coming from the stomach) will damage the small intestine walls.
