Answer: d. A bar graph indicating average high and low temperatures for Amanda’s area in the autumn, winter, spring, and summer.
A scientific study requires the use of variables, on the basis of which the outcome of the study can be obtained. An independent variable refers to a variable which can be changed or manipulated in an experiment, such changes will affect the dependent variables. Dependent variables is the outcome of the research, it cannot be changed manually instead the changes occur are because of the changes in the independent variable.
In the given situation, a bar graph indicating average high and low temperatures for Amanda’s area in the autumn, winter, spring, and summer would be an effective scientific model to be incorporated in the Amanda project. This is because of the fact that both independent and dependent variables can be analyzed by this way. The temperature is an independent variable, which changes with respect to the climatic conditions, which represent a particular season like autumn, winter, spring and summer which is a dependent variable.
Answer:
B. Water evaporates more quickly when temperatures are high
Explanation:
Constructing an hypothesis is KEY to any experimental setup. It is the first thing to do in accordance to the scientific method. A hypothesis is simply a predicted statement that aims at proferring solution that is subject to testing via experimentation.
According to this question, Mae observed that the birdbath in her backyard loses water more quickly during hot summer days than during the cooler days of the spring. A suitable hypothetical statement for this observation would be: "Water evaporates more quickly when temperatures are high".
N.B: Hypotheses are not questions
Answer:
Polar
Explanation:
In a water molecule, the oxygen atom is bigger and has a greater pull on the electrons than the hydrogen atoms do. This makes the molecule polar.
anmal cell
Explanation:
plants cell are gas cuz they smell good
Nucleic acids because the DNA of a organic compound is part of the nuculis family
