after seeing lightning flash you hear the clap of Thunder 5 seconds later how far away is the lightning (speed of sound=340 m/s)

Alecsey [184]

So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck.

Hair Coloring Experiment

leva [86]

The independent variable (hair colorin) causes a response in the dependent one (colorin effectiveness). The constant variable can not change (curly or straight), the control variable is kept constant (time and environmental conditions). The experimental group receives the treatment (40 students).

------------------------------------------------

INDEPENDENT VARIABLE

Refers to all the variables in an experiment that provoke a response in another variable. The independent variable is modified to analyze its effects on another variable. The researcher changes on purpose the independent variable to observe the response of the dependent variable.

In the exposed example, the independent variable is the red hair coloring

- Red Hair Paint

- L’Oreal

DEPENDENT VARIABLE

Refers to the variable, which response depends on any change in the independent variable. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable.

In the exposed example, the dependent variable is the coloring effectiveness, seen through how well the coloring takes and lasts.

CONSTANTS

This variable does not change during the whole experiment and under any circumstance. It can not change.

In the exposed example, the constant variable is the type of hair, curly or straight.

CONTROL

Controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.

In the exposed example, the controlled variables are the exposure time to the colorings and environmental conditions, such as temperature, humidity, etc.

EXPERIMENTAL GROUP

The experimental group receives the treatment. The researcher apply different treatments to the experimental groups to observe how they affect the dependent variable. There can be several experimental groups.

In the exposed example, the general experimental group is the 40 students' hairs. Because coloring does not have the same effect on different hair colors, the experimental group includes,

- 10 blonds,

- 10 brunettes,

- 10 with black hair

- 10 with red hair

If the grass contains 100,000 kcal of energy, how much energy will a fox obtain from eating a bird? 10,000 kcal 1,000 kcal 100 k

lawyer [7]

If the grass contains 100,000 kcal of energy, the energy a fox will obtain from eating a bird is 1,000 kcal.

<h3>What is Calorie?</h3>

This is defined as a unit of energy and it decreases as it moves up the food web in the ecosystem.

The organisms only derive 10 percent of the energy when the feed on others. In this case, the grass has 100,000 kcal of energy which when eaten by the bird will be 10 percent which is 10,000 kcal. When the fox eats the bird it becomes 1,000 kcal.

Which process is occuring when a vesicle fuses with the cell membrane and releases it's contents outside the cell?

xeze [42]

During the process of exocytosis, the cell membrane extends to engulf substances that are too big to pass through the cell membrane. Receptor proteins bind to signal molecules outside the cell.
