Answer:
1) d. observe phenomenon; generate hypothesis, conduct experiment, accept, reject, or modify hypothesis.
C. A study that compares a aroup of people with diabetes to a similar aroup of people without diabetes is an example of a case-control study.
Explanation:
Scientific method is a step by step procedure ranging from observing a problem to actual experimentation that aims at investigating a problem. The steps involved in the scientific method are as follows:
a)observe phenomenon; This precedes every experiment in the scientific method.
b) generate hypothesis: This is a testable explanation given as a possible solution to the observed problem.
c) conduct experiment: The hypothesis is tested via experimentation.
d) accept, reject, or modify hypothesis: Based on the result of the experiment, the hypothesis can be rejected, accepted or even modified.
Question 2:
Case control study is a type of study design that uses or compares a group of affected individuals (by a disease) called CASES and unaffected individuals called CONTROL. In this case, A study that compares a group of people with diabetes (cases) to a similar aroup of people without diabetes (control) is an example of a case-control study.
Gas: when the water has evaporated and is now out in the air. Water molecules move super fast during this stage.
Liquid: Water molecules have a good amount of space to move around, but they aren’t traveling as fast as they do in the gastric state.
Solid: ice in other words, the water molecules are super tight and compact, but are still moving around, just not very fast.
Cuando el hielo se calienta, comienza a derretirse y a formar agua, esto es progresivo
The pH will decrease because lemon juice is very acidic meaning it would bring the pH level down to a more acidic value.
