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.

Explain How are speed and pressure of a fluid related?
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.

How are signals “transmitted” into the cell?
Answer:
Generally, it is the brain that sends signals to parts of the body. It'[s the main headquarters for transmissions and orders.
Explanation:
Inside cells, electrical signs are passed on along the cell layer. Second, for correspondence between cells, the electrical signals by and large are changed over into compound signs passed on by little courier particles called synapses.

Answer:
Form a concave meniscus.
Explanation:
Putting water in a drinking glass, it will try to climb up the sides just a little bit, forming a concave meniscus.When pouring the water out, you have to visualize that the water still prefers to adhere to the glass than fall down under gravity, so if it at all can, that is what it will do.

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

Cells need to bring in molecules to carry out cellular processes. Often, this requires
moving the molecules across the cell membrane against the concentration gradient.
How do these molecules get into the cell?
Answer:
Active transport
Explanation:
The text is most likely speaking about active transport, such as endocytosis and exocytosis, which is essentially the process in which a cell uses to consume larger particles/molecules and expose of them, respectively.
difference between viruses and cells?
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.
