1. What are the independent and dependent variables in each of the experiments?

Biology
1 answer:
Dafna1 [17]1 year ago
6 0
  • The independent variables are temperature, airflow, and light and the dependent variable in each of the experiments is evaporation.
  • The schematic representation in the diagram helps in the understanding of the setup for the experiments.
  • The level of temperature, the rate of airflow, and the intensity of light must be controlled in the experiments.
  • A person will not be confident in experiment 3 results as the temperature is the independent variable that alters the results of evaporation.

<h3>What are the four foremost factors of a managed test?</h3>

When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.

  • In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.

The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.

  • The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.

  • The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.

  • The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.

  • The flow chart for the increase in pressure affecting the evaporation is given in the image attached.

Explain how the sun determines climate distribution. What type of weather conditions does the sun control?
Mashutka [201]

Answer:

The rate of energy coming from the Sun changes slightly day to day. It has been suggested that changes in solar output might affect our climate both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes

The Sun warms our planet, heating the surface, the oceans and the atmosphere. This energy to the atmosphere is one of the primary drivers our weather. Our climate is also strongly affected by the amount of solar radiation received at Earth.

Why is the frontal part of your brain important?
Kruka [31]

Answer: The brain is the vital organ in humans and each part of brain exhibit a distinct function.

Explanation:

The frontal part of the brain is responsible for controlling the cognitive skills, movement of the body, emotions, memory, judgement, sexual activity, linguistic skills, and others. It controls the behavior. It is the overall control panel of the human body. If the frontal lobe is damaged then this can negatively affect the human personality. The person suffers from difficulty in concentrating as well as planning.

During a test in the laboratory, an athlete ran at 10.0 mph for a period of time. At the start of the test, the treadmill speed
sleet_krkn [62]

Answer:

The correct answer is option a.

Explanation:

Power output refers to the power exerted at the time of performing physical activities. Power output is one of the best means of determining athletic performance at the time of exercise or any physical activity. When the athlete jumped over the treadmill, his output power enhanced abruptly, while the power input enhanced slowly over a duration of one to two minutes.

What evidence is there that the universe is expanding? Explain.
Vsevolod [243]

This is evidenced by Doppler shift effect. This is the phenomenon where waves that are coming from an object that is accelerating towards your direction are heard at a higher frequency than that of objects moving away from you. This is the same for light (which also has wave-like properties). When observing distant galaxies, astronomers discovered that they all showed to be redshift (change in the frequency of light towards red color). This means that all galaxies are moving away from each other because the universe is expanding.
