<u>Answer:</u>
Angle of inclination is the independent variable.
Distance covered by the rolling ball is the dependent variable.
<u>Explanation:</u>
An independent variable is the one whose variation is not dependent on the value of any other variable while dependent variable changes its value with a change in the independent variable.
In this experiment, angle of inclination (angle between a line and the x-axis) is an independent variable whereas the the distance covered by the rolling ball is a dependent variable which will vary with a change in angle of inclination.
A. They trap some of the Sun’s heat energy within the atmosphere, helping to maintain Earth’s average temperature.
Answer:
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Explanation:
Answer:
0.01%
Explanation:
If the grass is 100%, then the grasshopper is 10%, the mouse is 1%, the snake is 0.1%, and the hawk is 0.01%. When you go up the trophic levels, you only get 10% of the energy left behind from the last level (in other words, you move the decimal point to the left by 1 place).
Respiration using oxygen to break down food molecules is called aerobic respiration. 'Aero' means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration - it is the main respiratory substrate. Glucose is oxidised to release its energy, which is then stored in ATP molecules.
The word equation for aerobic respiration is:
glucose + oxygen → carbon dioxide + water (+ ATP made)
You need to be able to recognise the chemical formulas:
C6H12O6 + 6O2 → 6CO2 + 6H2O
