Answer:
4.) because you can only change one factor in an experiment so if you notice something, you'll know what caused it.
5.) an assumption made before any research has been completed for the sake of testing. A theory on the other hand is a principle set to explain phenomena already supported by data
6.) science- the intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.

1. By how much did the three organisms investigated in this activity grow over the course of
ten weeks when the average water temperature was 20°C? (Save the
graphs of data to yourcomputer and paste them below to help answer this question.)
Answers
The graph of growth moves upward and downward due to temperature of the medium.
That organism which grow best in the temperature range from 15°C to 25°C, the graph moves in the upward direction due to the presence of optimum temperature for the growth of that organism.
The organism which grow best in the temperature range from 5°C to 15°C, the graph moves in the downward direction because the water temperature is not suitable for the growth of that organism.
The organism which grow best in the temperature range from 25°C to 35°C, the graph also moves in the downward direction because the water temperature is not good for its growth so we can conclude that the growth rate increases and decreases due to temperature of water.

The substance with the higher pH has 1,000 times as many hydrogen ions per volume of water. O
O The substance with the lower pH has 1,000 times as many hydrogen ions per volume of water.
Answers
Answer: c
Explanation: 3.0 is 1,000 times as many ions
The statement that best describes the difference is ; The substance with the lower pH has 1000 times as many hydrogen ions per volume of water. ( D )
Given that the substance have pH ; 3 and 6
To prove the statement above we will make use of the pH formula
pH = -log(H⁺)
for substance with pH = 3
3 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻³
for substance with pH = 6
6 = - log(H⁺)
H⁺ ( hydrogen ions ) = 10⁻⁶
Hence we can state that the substance with the lower pH has 1000 times as many hydrogen ions per volume of water

Sign an experiment.
A: John Smith has been hired by the city of Virginia Beach to investigate the recent increase in shark attacks off
the resort's coast. The resort has also heard from its guest recently an increased number of elephant seals that
are seen at the beach. Elephant seals are highly migratory and move with the seasons. He has a budget of
$40,000, a 25 foot boat, and three graduate student assistants to help him. A helicopter has also been donated by
a local television station, should he need one.
1. List 2 hypotheses John and his crew may have come up with for the recent shark attacks.
a. If
then
b. If
then
2. Pick one of the two hypotheses and determine the following:
a. Control Group:
b. Experimental Group:
c. Dependent Variable:
d. Independent Variable:
3. What type of data do you think John will collect (What will be the results of the experiment)?
4. What conclusions will John be able to make from the results of the experiment?
Answers
The answers to the questions required for the design experiment above are :
If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal. The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach. The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low). The Dependent variable : Number of shark attacks The Independent variable : The different number of elephant seals found. Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points. John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.
The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.
The Experimental group are the portion of the subjects which are subjected to the treatment condition.
The Dependent variable is the measured variable is changes as the independent variables are tweaked.
Independent variable is the predictor variable, it causes a change in the output of the dependent variable.

The earth's surface tends to lose heat in winter. Which of the above cities would have the warmest average winter temperature? Why?
Since the sun is approximately 93 million miles from the earth and space has no temperature, how do we get heat from the sun?
How would the uneven energy absorption by different surfaces on earth (water, soil, snow, trees, sand, etc.) affect the atmosphere?
Answers
Explanation:
Of the energy that reaches the Earth from the Sun, a small amount is absorbed by the atmosphere, a larger amount (about 30%) is reflected back to space by clouds and the Earth's surface, and most of it is absorbed at the planet surface and then released as heat.
Energy is transferred between the Earth's surface and the atmosphere in a variety of ways, including radiation, conduction, and convection.
Molecules of all substances, even solids, have random motion and therefore an associated kinetic energy and temperature. ... Completely empty space would have no temperature since there are no molecules there.

What would be the best negative control to use when testing for any organic compounds
Answers
Explanation:
A similar question was asked online, here is the answer it gave:
'“Negative control” is a treatment that by definition is expected not to have any effect (neither positive effect, nor negative effect). “Positive control” is treatment with a well-known chemical that is known to produce the expected effect with the assay that you are studying. Application of an antagonist is not a negative control in your case. “Negative control” is condition that should be treated with the same solutions or buffers as your “treatment” condition, with the only difference that instead of the chemical that you investigate you should add just the solvent that was used to dissolve you chemical in the respective final concentration that you have in the “experimental treatment” condition. For example if your chemical is dissolved in DMSO – than the correct negative control will be to add to the medium/buffer just DMSO in the same final concentration that you reach with your “treatment” condition. One of the reasons of using such negative control is to verify that the solvent is having no effect in your assay. Note that among all treatment conditions (“negative control”, “positive control”, “experimental treatment you are investigating”) the volumes and the composition of the treatments that you are doing should be uniform: always treat with the same volume of medium or buffer, always containing the same concentration of the used solvent (e.g., DMSO). The only difference should be the presence or absence of the defined compound-treatments (agonist, antagonist, the chemical for the experimental investigation etc.).'
My best advice is to use the textbook you have, or use examples of a negative control when testing organic compounds because you have to find something that you can assign, like a worm in a box of dirt, the worm could have enough food to survive, so that is your negative control, but when it comes to finding the best, that would have to rely on something within the parameters of being self sufficient like a plant getting its energy from photosynthesis, etc.

(Side note: haha I just finished this for a class today)
Explanation:
There are many things to define something as living such as certain properties. There properties might include things such as growth and development, there energy source, response to the environment, there internal balance, and reproduction.
These all have a big role in telling us whether something is living or nonliving. What it means to be living is to have certain characteristics nonliving organisms might not have. Like flowers there energy source would be the sun, they grow with water and the sun, and response to the environment could mean like how some flowers grow towards the sun, flowers reproduce with their seeds. To be living is to have everything working together in the right spots at one time. Like how your different body systems work together to keep you alive.

Although we think of land when we hear the word biome, there are also aquatic biomes. The abiotic factors that
influence life forms vary with location within ocean systems. Oceanographers divide the ocean into five broad vertical
zones as seen in the chart above. Compare the characteristics of the five zones. The giant tube worms, Riftia
pachyptila, pictured here, have a red "plume at the tip of their free end which is an organ for exchanging compounds
with the environment. The tube worm does not have many predators. If threatened, the plume may be retracted into
the worm's protective tube. The plume provides essential nutrients to bacteria living inside the worm. Tube worms
have no digestive tract, but the bacteria, which may make up half of a worm's body weight, convert the oxygen,
hydrogen sulfide, carbon dioxide, taken in by the plume, into organic molecules on which their host worms feed.
Compare this information with the information in the chart. Where could these worms live?
A)
The tube worms can only live where there is no light: zones 3, 4, and 5.
B)
C)
Only in the top-most two zones so the bacteria can use the light for
photosynthesis.

Answer:
D) They tube worms are suited to live in the halad zone only, where there is no light and it is extremely cold.
Explanation:
Although these tube worms reside in the trenches of the Halad zone at the lowest layer, they survive in darkness and freezing temperatures. Additionally, there are other species of starfish that inhabit this area, thus the starfish are also companions.
