Which statement is a hypothesis? Jada decides to investigate the effectiveness of hand sanitizers compared to soap. She says tha
t hand sanitizers are as effective as soap in destroying bacteria. Many sanitizers have alcohol as their main component. She performs a study in which people use sanitizers for one week and then soap for another week. She then examines the bacterial count.
Hand sanitizers are as effective as soap in destroying bacteria.
Explanation:
A hypothesis is a supposition that is made with limited evidence. Jada is performing this experiment to provide further evidence either supporting or rejecting her theory of whether hand sanitizers are as effective as soap.
Plate boundary zones are the interaction between adjoining plates where they clash, pull separated or slide past each other.
These newly created zones can be a long stretch from few kilometers to hundreds of kilometers.
It is the movement between two plates and the distortion that come about in the boundaries of the zone between the plates, which has given birth to New Zealand's geography which we see it today.
The distortion and mashing caused by the hit of the two great plates have created mountain ranges throughout the country.
D - Other scientists can validate or disprove the findings
Explanation:
Publishing findings of their research projects is important as it enables peer-revision on their journals. The work can then be evaluated by the community at-large to validate or disprove it, which opens the dialogue with associate researchers.
