1. A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of people were created. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored.


Dependent Variable: ______________________ Control Group: ____________________________


Independent Variable: _____________________ Experimental Group: _______________________

Answers

Answer 1

Answer:

Independent variable: Jazz

Dependent variable: Amount of time used to sleep

Control group: The group that was placed in a quiet room

Experimental group: The group that was placed in a room where jazz music played softly

Explanation:

In an experiment, the independent variable refers to the variable being changed or manipulated by the experimenter in order to bring about a measurable response. In this experiment, the independent variable is the JAZZ used.

Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the AMOUNT OF TIME SPENT SLEEPING.

Control groups are the groups in an experiment that do not receive the experimental treatment (jazz music). Hence, the GROUP THAT WAS PLACED IN A QUIET ROOM is the CONTROL GROUP.

Experimental group, on the other hand, is the group that receives the experimental treatment in an experiment. In this case, the experimental group is the GROUP THAT WAS PLACED IN A ROOM WHERE JAZZ MUSIC WAS PLAYED SOFTLY.

Answers

Answer:
Starch

Explanation:
Digestion begins in the mouth. The teeth break down food from chewing through mechanical digestion.

Chemical digestion also begins in the mouth. Saliva moistens food, but it contains an important enzyme called amylase. This enzyme breaks down starch into simple sugars.

So, the first compounds that are digested are starch.

Which type of tissue produces movement?
A. Nervous tissue
O B. Epithelial tissue
O C. Connective tissue
O D. Muscle tissue

Answers

D. Muscle tissue.
Hope it helps

The type of tissue which produces the movement is known as Muscle Tissue. The correct option is D.

Muscle tissue is made up of cells that have the unique ability to shorten or contract in order to move bodily parts. The tissue is densely cellular and rich in blood capillaries. Because the cells are long and slender, they are sometimes referred to as muscle fibers, and they are typically organized in bundles or layers surrounded by connective tissue.

Actin and myosin are muscular proteins found in muscle. Skeletal muscle tissue, smooth muscle tissue, and heart muscle tissue are the three types of muscle tissue.

Answers

Answer:

The higher the velocity of a fluid (liquid or gas), the lower the pressure it exerts. This is called Bernoulli’s Principle. Fluid pressure is caused by the random motion of the fluid molecules. When the fluid speeds up, some of the energy from that random motion is used to move faster in the fluid’s direction of motion.

difference between viruses and cells?

Answers

Answer:Cells exist by themselves such as bacteria....

Whilst Virus are non loving infectious particles and need a living host to reproduce.

Answer:

Cells are the basic units of life. Cells can exist by themselves, like bacteria, or as part of a larger organism, like our cells. Viruses are non-living infectious particles, much smaller than a cell, and need a living host to reproduce. The genetic material of the cell is DNA, a double stranded helix.

Another reason is because they can't reproduce by themselves (without a host), viruses are not considered living. Nor do viruses have cells: they're very small, much smaller than the cells of living things, and are basically just packages of nucleic acid and protein.
