When a cat drops from a tree to the ground, the cat is transforming chemical energy attained from the food into kinetic energy. The later energy is used by the living species when they are performing locomotion.
When a cat feeds on a mouse, the mouse will undergo through the process of digestion resulting in the formation of chemical energy. Thus, the food consumed by the cat will get transformed into chemical energy that can be utilized by the cat to perform its usual activities.
Answer:
A. Carbon dioxide gas forms because an acid and a carbonate react.
Although not specified, I am assuming that you want to identify the different variables and groups of this case. To answer this, the different typical factors that make up an experimental set up include: 1) dependent and 2) independent variables; 3) controlled variables; as well as the 4) control and 5) experimental group.
The dependent variable in this case is: the size of the population. While the independent variable is: the habitat space. Controlled variables in this experiment include: type and amount of food, cleanliness of the aquarium, and water temperature. The experimental group are simply the fish being observed. There are no controlled groups in this case depending on your definition. Controlled groups are usually the reference point or standard in experimental setups but this experiment wants to look at the differences of the goldfish with each other and not necessarily to a one particular goldfish and hence no controlled group.
The dependent variable is called as such because it is the one that changes depending on the factors given and is usually the one being observed. The independent variable is named as such because it remains the same throughout the experiment.
<span>The correct answer is
(a) True, it is of paramount importance to use primary, secondary, and tertiary
sources in research. Researching includes using primary sources as they contain
original materials on which research is based, but also using second sources as
interpretations and evaluations as other researcher’s point of view. That also
apply for tertiary sources that
represent distillated and collected information of primary and secondary
sources.</span>
