Answer:
The answer would be to always wash your hands!
Matter can change from one state to another when thermal energy is absorbed or released. A great example is Ice having its state changed to the liquid that is WATER. When ice is heated, it absorbs thermal energy and its temperature rises. At some point, the temperature stops rising and the ice begins to change to water, a liquid. As we all know, The change from the solid state to the liquid state is called melting.
Some of the aspects that help you determine whether a study is rigorous are questions and hypotheses that can be answered, adequated method use, and bibliography.
Rigorous is a term that refers to a quality that focuses on accuracy and precision to comply with norms, precepts, and pre-established rules. This term is widely used in science to refer to the precision of a study or investigation.
Therefore, when it is established that a study is rigorous, its attributes must be taken into account, such as:
- Questions and hypotheses that can be answered: This aspect refers to the investigator having the ability to limit his study so that it is appropriate to do so and does not include too much information that makes his study "impossible".
- Adequated methods use: This refers to using the appropriate methods to reach feasible conclusions, for example, methods of observation, deduction, induction, among others.
- Bibliography: This refers to the research or study being supported by reliable sources so that it is as accurate as the information it provides.

<span>A tiger looks so much different as an adult than it did as a single fertilized egg because it developed through different stages from being a zygote (fertilized egg), to becoming an embryo (where it experiences intense cellular changes), to becoming a fetus (where it gains a great measure of cell specialization, and develops distinct tissues and organ systems). After birth, the tiger still undergoes further growth and development into adulthood. This is largely regulated by the expression of different genes at different times and also by environmental factors.</span>
The right answer is Filtration.
A water filter is composed of a filtration system that aims to separate the water from the solid particles (residues) by passing it through a porous medium, which allows only the liquids and the finer solid particles to pass through. as the filter holes (porosity). The water that comes out of this filtration system is rid of solid particles larger than the pores of the filter.
Some water filters are designed to make drinking water (very fine filtration, less than the size of a microbe).
