Independent and Dependent Variable Practice
DIRECTIONS: Read the information about each experiment and record the independent variable (IV) and dependent variable (DV). Then write a hypothesis for each experiment. Be sure to use an “if, then, because” statement.
Will an egg float higher in water with more salt?
IV:
DV:
Hypothesis:
Willy and Billy want to know if stretching a rubber band at different lengths affects how far the rubber band will fly. They will use centimeters for all measurements.

Hypothesis:
Will a plant grow higher with more light?

Hypothesis:
Milly and Bob want to know if the amount of baking soda added to vinegar will affect the height a rocket will launch. They will measure the baking soda in milliliters. They will measure the height of the rocket launch in meters.
IV:

Hypothesis:
Carrie and Heather wanted to know if the size of a coin will affect the number of drops of water it can hold. So they use a dropper to place water on a quarter, nickel, and penny.
IV:
DV:
Hypothesis:
I wonder if the amount of studying I complete has an effect on my science test scores?
IV:
DV:
Hypothesis:
Answer:
1) IV: The quantity of salt added
DV: The resultant density of the salinated water
Hypothesis: The egg will float when the mass of the volume of the salinated solution displaced by the egg is equal to or larger than the mass of the egg
2) IV: The extension of the rubber band above original length in centimetres
DV: The distance flown by the rubber band
Hypothesis: The potential energy stored in the rubber band by pulling will be transformed into kinetic energy and the larger the extension, the larger the stored potential energy, and the larger the resultant kinetic energy, the higher the velocity and the further the distance flown
3) IV: The wing span of a paper airplane
DV: The distance flown by the plane
Hypothesis; The glide of the airplane is a factor of the wings span increased wingspan increased glide and increased travel distance
4) IV: Presence of more light
DV: Height to which plant grows
Hypothesis: Photosynthesis, which is the conversion of carbon dioxide and water into glucose and oxygen in the presence of Sunlight is essential for plant growth and the more the presence on light is increases the higher plant will tend to grow
5) IV: Amount of vinegar in the canister
DV: The height a rocket will launch
Hypothesis: With a given amount of baking soda, in the canister a little amount of vinegar causes a delayed launch but an increased build up of carbon dioxide resulting in higher height reached than when more vinegar is used in which case the lift off will be more rapid but the power will be lesser and the height reached reduced
6: IV: Surface area of the coin
DV: The number of drops held
Hypothesis: Due to surface tension and cohesion which are properties that increase with surface area and as such a coin with a larger surface area holds more water drops
7. IV: Number of hours of study
DV: Science score
Hypothesis: A student science scores is directly related to the amount of science topics thought the student is able to respond to in a test and it is directly proportional to the amount of study the student has done related to the science topics
Explanation:
In South America, huge areas of tropical forests are being cleared. The wood is sold and crops such as coffee are planted instead.
a) Give two reasons why this damages the global environment.
b) Suggest two ways of limiting the damage to the forests.
a) Give two reasons why this damages the global environment
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.b) Suggest two ways of limiting the damage to the forests
reinforcing and expanding forest protected areas; and adopting agroforestry, afforestation and reforestation and sustainably managing existing planted forests to meet demand for wood, thereby reducing pressure on natural forests.HOPE SO IT HELPS YOU

Why are the testes located in the scrotum rather than inside the ventral body cavity? _______________________________
Answer:
the scrotum provides a slightly cooler temperature for optimal sperm production
Explanation:
Imagine an invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have:____. a. a cyclic variation depending upon when the animal drinks. b. regular variations that range from large to small. c. slight fluctuations that are kept within a narrow range. d. a cyclic variation opposite that of the surrounding water.
Answer: Option C.
slight fluctuations that are kept within a narrow range.
Explanation:
An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).
Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.

how is the frictional force produced?
Answer:
Frictional force refers to the force generated by two surfaces that contacts and slide against each other, If an object is pushed against the surface, then the frictional force will be increased and becomes more than the weight of the object
Explain how scientific knowledge develops through making observations about the natural world.

Explanation:
please help me out, name all 3 parts of the atom.
In the atom, the arrow 1 depicts the proton. The arrow 2 depicts the neutrons, and the arrow 3 depicts the electrons. All three of these are subatomic particles.
What is an atom?An atom is the fundamental structural unit of matter. It consists of protons, neutrons, and electrons. Electrons are negatively charged particles that are present outermost shell of the atom, while protons are positively charged particles that make up the core of the atom. The neutron doesn't have any charge.
Both neutrons and protons make up the core of an atom, while electrons revolve around them. A neutral atom has equal numbers of protons and electrons. Example: the sodium atom.
Hence, the atom showing arrow 1 is a proton, arrow 2 is a neutron, and arrow 3 is an electron.

Rapid burial _____.
increases exposure to oxygen
decreases exposure to oxygen
slows down the rate of decay
prevents scavengers from eating organism remains
Answer:Organisms decompose more quickly when they are in contact with oxygen. Most environments exposed to the open air are in contact with plenty of oxygen, so the soft tissues of dead organisms, whether plants or animals, decay quickly. ... For an organism to become a fossil, it must not decompose or be eaten.

Explanation:
Indicate which of the following statements is TRUE. Group of answer choices Covalent bonds connect nucleotides in a strand; noncovalent interactions hold strands into a double-stranded structure. Uracil is similar to thymine except that uracil lacks a methyl group on the carbon at position 5 on the carbon-nitrogen ring. Frederick Griffith demonstrated that a transforming chemical from dead bacteria could change the genetic information of living bacteria. The pyrimidine bases in nucleic acids are cytosine, thymine, and uracil. All of the above statements are true.
Answer:
The answer is "All of the above statements are true".
Explanation:
In the given-question all choices were true, which can be defined as follows:
The covalent bonds are linked to a range of nucleic acids. Non-covalent encounters involve a dual washed ashore system. The Uracil is just the same as pyrimidines, except that at position 5 throughout the carbohydrate ring it lacks in the methyl group in carbon. Frederick-Griffith proved a possible change throughout the genetic material of bacterial cells with both the morphing chemical from dead bacterial cells. Cytosine, thymine, and uracil are pyrimidine fundamentals in nucleic acids.how does root pressure move water
