Correct Answer
A. Parasitismo,canibalismo,amensalismo
Explanation The correct answer includes examples of only negative or harmful interactions between organisms. Parasitism is a relationship where one organism benefits at the expense of another, canibalism is when an organism eats another organism of the same species, and amensalism is a relationship where one organism is harmed while the other is unaffected. These examples demonstrate relationships where one organism is negatively affected, either by being exploited, consumed, or inhibited, by another organism.
Explanation The correct answer is "sólido, lÃquido e gasoso." This answer correctly identifies the three states of matter, which are solid, liquid, and gas. These states describe the different physical forms that matter can exist in based on its temperature and pressure conditions. In the solid state, matter has a fixed shape and volume. In the liquid state, matter has a definite volume but takes the shape of its container. In the gas state, matter has no fixed shape or volume and fills the entire space available to it.
Explanation When a substance goes directly from a solid state to a liquid state, it is an example of sublimation. Sublimation occurs when the substance bypasses the liquid state and changes directly into a gas. This process typically happens under specific conditions of temperature and pressure.

O processo de vaporização compreende:
A.
Ebulição, sublimação,evaporação
B.
Ebulição, calefação,condensação
C.
Evaporação,ebulição,fusão
D.
Fusão,ebulição, calefação
E.
Calefação,evaporação,ebulição
Correct Answer
E. Calefação,evaporação,ebulição
Explanation The correct answer is "calefação, evaporação, ebulição." Calefação refers to the process of heating a substance to convert it into a gas or vapor. Evaporação is the process of a liquid turning into a gas at a temperature below its boiling point. Ebulição is the process of a liquid reaching its boiling point and turning into a gas. Therefore, the correct answer includes the correct sequence of these three processes.
Correct Answer
A. Passagem do lÃquido para o estado gasoso
Explanation The correct answer is "passagem do lÃquido para o estado gasoso." This is because "ebulição" is the Portuguese word for "boiling," which refers to the process of a liquid reaching its boiling point and converting into a gas.

Exemplo de ebulição e calefação:
A.
Salinas e água fervendo
B.
Roupa secando ao sol e salinas
C.
Frigideira quente quando bate água e roupas secando ao sol
D.
água fervendo e frigideira quente quando bate água
E.
água fervendo e roupas secando ao sol
Correct Answer
D. água fervendo e frigideira quente quando bate água
Explanation The correct answer is "água fervendo e frigideira quente quando bate água". This answer is correct because both scenarios involve the heating of water. In the first scenario, the water is boiling, which is a form of boiling. In the second scenario, when water is splashed onto a hot frying pan, it quickly evaporates, indicating that the frying pan is hot. Therefore, both scenarios involve the process of heating water.

Quando aumentamos a altitude a água ferve a uma temperatura...
A.
Menor
B.
Maior
C.
Não modifica
D.
O dobro do nÃvel do mar
E.
A metade do nÃvel do mar
Correct Answer
A. Menor
Explanation When we increase altitude, the atmospheric pressure decreases. As a result, the boiling point of water decreases as well. This means that water will boil at a lower temperature at higher altitudes compared to sea level. Therefore, the correct answer is "menor" which means "lower" in English.
Explanation This answer is correct because it includes two examples of alternative energy sources: solar and wind. Solar energy refers to the use of sunlight to generate electricity or heat, while wind energy involves harnessing the power of wind to generate electricity. Both of these sources are considered alternatives to traditional fossil fuels and are renewable and environmentally friendly.
Explanation The given answer, "calefação," is correct because it refers to the process of heating or boiling. In the given scenario, when a drop of water falls onto a boiling plate, it undergoes rapid heating and eventually turns into steam. This process is an example of calefação, as it involves the transfer of heat energy from the boiling plate to the water, causing it to heat up and change its state.
Explanation In the liquid state, molecules are not fixed in a specific shape and are able to move freely. They are not restricted to a rigid structure like in solids, but they still have some degree of attraction between them. This allows them to flow and take the shape of the container they are placed in.
Correct Answer passando do estado sólido para o liquido
Explanation The correct answer is "passando do estado sólido para o lÃquido" because when we say that glaciers are melting due to global warming, it means that they are transitioning from a solid state to a liquid state.

Se retirassemos todas as plantas do planeta os seriam os primeiros afetados pela falta de alimentos.
Correct Answer consumidores primários
Explanation If all plants were removed from the planet, the primary consumers would be the first to be affected by the lack of food. Primary consumers are organisms that directly feed on plants, such as herbivores. Since plants are the primary source of food for these organisms, their absence would lead to a scarcity of food and ultimately affect the survival of primary consumers.
Os fatores bióticos são os componentes ____________do ambiente já os abióticos são os componentes___________________.
Correct Answer vivos, não vivos
Explanation The correct answer is "vivos, não vivos". This is because "fatores bióticos" refers to the living components of the environment, such as plants and animals, while "fatores abióticos" refers to the non-living components, such as temperature, sunlight, and soil composition.
