Answer:
Many animals have evolved fur or feather colors to blend in with the environment and hide from predators. But how do animals stay camouflaged when their environment changes with each new season? For snowshoe hares, hybridization plays an important role in their ability to match their environment
Explanation:
Answer:
This is like having enough energy to supply the world for centuries with just 1% of the sea's force? The amount of energy in it can supply energy therefore the one drop of tea is able to run her air conditioning for the rest of her life.
Explanation:
In order to answer this question, we are going to look at the molar ratio between H2O and H2, we can see that by analyzing the numbers in front of the compounds, and we can see that the molar ratio is 2:2, this means that for every 2 moles of water decomposing, we will end up with 2 moles of H2 being produced, therefore the same amount of moles for H2O will be the same amount of moles of H2, which means that if we have 100 moles of H2O being decomposed, we will also have 100 moles of H2 being produced.
Answer:
This question is incomplete but the missing part is in the picture attached.
Explanation:
A mixture of silicon oxide, ammonium chloride and sodium chloride were to be separated. Three separating techniques were used in the experiment; sublimation, decantation and evaporation.
Sublimation is the process in which a substance changes from solid to gas without passing through the liquid phase. <u>Ammonium chloride (NH₄Cl) is a substance that has the ability to sublime</u> and thus was separated first through this property before adding water to the remaining constituents (silicon oxide and sodium chloride) of the mixture. After the addition of water to the mixture, <u>sodium chloride dissolves in this water while silicon oxide does not dissolve in water</u>. The mixture is then left to stand for some minutes so the <u>undissolved sand can settle at the bottom of the mixture</u> and the <u>dissolved salt water can be decanted out</u> so as to have the silicon oxide left in the jar.
The <u>salt solution decanted will have to be evaporated to dryness</u> (to remove the added water) so as to have the solid salt back.
Answer:
Conducting experiments and using the scientific method.
Explanation:
Scientists (and other people) test hypotheses by conducting experiments. The purpose of an experiment is to determine whether observations of the real world agree with or conflict with the predictions derived from a hypothesis. If they agree, confidence in the hypothesis increases; otherwise, it decreases.
