Carmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30-second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music. Which component is missing from Carmen’s experiment?

Why is the polarity of water molecules and hydrogen bonding essential to adhesion and cohesion?
Answers
Some properties like Polarity makes water a good solvent, cohesion helps in stick water molecule to itself while adhesion helps it to stick with other surfaces. Water have surface tension due to hydrogen bonding.
What are the difference between adhesion and cohesion ?when two similar molecule come closer adhesion occur where as in cohesion two similar molecules face the force of attraction.
Adhesion is the force of attraction observed between the water molecules and xylem vessels while Cohesion is unrestrained among water molecules.
Capillary action and meniscus are the effects of adhesion while Surface tension, meniscus and capillary action are the effects of cohesion.
The major forces responsible for adhesion are electrostatic or mechanical forces while Cohesion is the result of hydrogen bonding and Van der Waals forces.
A strong adhesion can lead to spread of liquid all over the surface while cohesion forms water droplets.

Which is one event that may lead to Primary succession? clear-cutting climate change volcanic eruption introduced species
Answers
Answer:
Primary Succession is when an uninhabited area becomes an ecosystem, and Secondary secession is when an ecosystem is destroyed an Independent factor, like a fire, a hurricane, stuff like that.
Explanation:
Clear-cutting climate change would be an example of Secondary Secession, and volcanic eruption introduced species would be an example of Primary Secession.
Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time.
The event that may lead to Primary succession is: volcanic eruption
What are the three causes of primary succession?The main causes of ecological succession include the biotic and climatic factors that can destroy the populations of an area. Wind, fire, soil erosion and natural disasters include the climatic factors.
What organisms come first after a volcanic eruption then what happens?Lava from a volcanic eruption hardens into bare rock. Primary succession begins with soil formation. The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens.
