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:
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.
How does cellular respiration demonstrate
the conservation of mass?
Answers
Cellular respiration is the process by which cells obtain energy from glucose. It can be represented by a chemical reaction which, when balanced, obeys the Law of Conservation of Matter:
C6H1206 + 6O2 ---- 6CO2 + 6H2O
Th number of atoms of reactants equals the number of atoms of products:
six carbon atoms, 12 hydrogen atoms, 18 oxygen atoms
No atoms are created or destroyed in this process, they're just rearranged into different molecules.
We often hear the term "burn" to describe glucose being used by living things for energy. When a substance burns, matter is conserved. It might seem like the burned substance is completely consumed because the products, CO2 and water, are both produced in the gaseous form and are colorless and invisible. The French chemist Antoine Lavoisier was the first to show that mass is conserved in chemical reactions by carrying out combustion reactions in a closed system and capturing the gaseous products.
Cells use cellular respiration to convert glucose into energy for cellular function. A chemical process that, when balanced, complies with the Law of Conservation of Matter might serve as a metaphor for it:
6CO2 + 6H2O = C6H1206 + 6O2
What is cellular respiration?
Cellular respiration converts glucose into ATP, which powers various physiological functions. Cellular respiration involves glycolysis, the citric acid cycle, and oxidative phosphorylation.
Glucose fuels cellular respiration. A balanced chemical reaction represents it:
6CO2 + 6H2O = C6H1206 + 6O2
Reactants and products have equivalent atom counts.
This technique rearranges atoms into molecules without creating or destroying them. Living creatures "burn" glucose for energy. Burning conserves matter. Because CO2 and water are gaseous, colourless, and invisible, it may seem that the burnt material is totally consumed. Antoine Lavoisier was the first to demonstrate mass conservation in chemical reactions by conducting combustion processes in a closed system and catching the gaseous products.

Which of the following most likely indicates that a chemical change has
happened?
A. A plate breaks when it falls to the floor.
B. There's a loud sound when a jet airplane starts its engines.
C. An icicle melts in the sun.
D. A can is crushed when it is stepped on.
Answers
Answer:
Option B
Explanation:
A plate breaking when falling to the floor would be a physical change, not chemical, as what the plate is created from would not change.
An icicle melting in the sun would be a physical change, as an icicle is frozen water, and after melting it would be normal water.
A can being crushed is still just a physical change, as the material making the can(typically aluminum) has not changed.
When a jet airplane starts its engines, fuel is combusted, creating energy for the engines to start. This would create the loud noise. As fuel is combusted, it turns into different things, henceforth the sound would imply a chemical change has occurred.

(Choice D) D It is an anabolic reaction.
Answers
Answer:
The correct answer is - (Choice A) A It is a catabolic reaction.
Explanation:
The catabolic reaction is a reaction that involves the sepration of larger molecules into smaller molecules and releases the energy stored in the chemical bond.
This metabolic reaction breaks the larger molecules into smaller and simple molecules for example in cellular respiration glucose molecule is broken down into water and carbon dioxide and releases energy in the form of ATP.
Answer: D- It is an anabolic reaction.
Explanation: This reaction is anabolic, since it consumes energy to build a more complex molecule from smaller ones.
2. What does it mean if a micrograph is "false-colored?"
Answers
It means that the object has color created by the computer since electron microscopes really see in black and white. ... They usually range in sizes between 5-50 micrometers, they are surrounded by a cell membrane, and usually can't be seen without a microscope.
A micrograph is said to be false-colored when there is color created by the
computer involved in the printing of the picture.
A micrograph is a pictorial representation of objects seen under a
microscope. The view of objects under microscope is usually in black and
white color. The micrograph is therefore meant to also be in black and white.
This is the reason why when there is a color in the micrograph, it is referred
to as being false-colored.

A scientist will have to develop new methods to test the hypothesis as a
result of humans taking long time to reproduce.
Hypothesis is an explanation for an occurrence or phenomenon in research.
It involves conducting different tests under the same and varying conditions
to confirm if the hypothesis is true which then becomes a law when
universally proven.
Testing of hypothesis is very important which is why developing new
methods which has a lesser time frame to test the hypothesis and not

The cell cycle is the regular sequence of growth and division that cells undergo.
True or false?
Answers
Answer:
True
Explanation:
The regular sequence of growth and division that cells undergo is known as the cell cycle. During the cell cycle, a cell grows, prepares for division, and divides into two new cells, which are called “daughter cells.” Each of the daughter cells then begins the cell cycle again.
Answer:
True
Explanation:
The cell cycle is the sequence of events involved in a cell's growth and division.
The cell spends most of the time in the interphase stage, where it can prepare for cell division by replicating chromosomes.
Then, it undergoes mitosis, where it splits into 2 daughter cells.
So, this statement is true, because cell division is the regular process that cells undergo to grow and divide.

How do organisms survive if the cells they are made of continually die?
Answers
Answer:
nope.................................
The strategy that multicellular organisms such as humans use to project themselves into the future is to create new cell colonies from a single undifferentiated cell rather than maintaining existing colonies indefinitely. The main reason is that reproduction is more flexible and robust than maintenance, and it provides a way of starting over with a “clean slate” and slightly different genes. Complex organisms accumulate billions of errors and problems over their lifetime. So basically organisms survive because new cells are made everytime a cell dies.

Lentic Systems and give examples
Answers
Answer:
Lentic is a class of aquatic ecosystems that are found on land, such as:
ponds
rivers
lakes
swamps
streams
Mostly, lentic ecosystems are described as still bodies of freshwater, and they are smaller ecosystems. Some lentic ecosystems contain animals and microorganisms, but they mostly rely on the photosynthesis of algae and underwater plants to produce energy to thrive. One of the requirements of a lentic body of water is that it is exposed to the sun to encourage photosynthesis.
Explanation:
A lentic ecosystem entails a body of standing water, ranging from ditches, seeps, ponds, seasonal pools, basin marshes and lakes. Deeper waters, such as lakes, may have layers of ecosystems, influenced by light. Ponds, due to their having more light penetration, are able to support a diverse range of water plants.
