2. IV: The soap used in the study
3. DV: Flower growth
Explanation:
A scientific question is a well-sustained question about a given phenomenon of the real world which can be answered by experimental and/or observational procedures. A good scientific question must be testable and lead to falsifiable hypotheses. The dependent variable is the variable that is being measured in the experiment, (i.e. it is being affected by the experimental procedure). On the other hand, the independent variable is the variable that isn't changed by the other variables that are being measured in the experiment.

What are the five categories of adaptations?
The five categories of adaptations are migration, hibernation, dormancy, camouflage, astivation.
What is migration?The term migration has been defined as when the birds, animals, or human beings leaves the native place and move towards a new place due to weather or other physical condition is known as migration. Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.
The stage of dormancy is the stage when seed gets closed and not able to germinate as it closes its outer wall. The term hibernation is defined as the particular time period in which the organism hybernate himself for a period of time when the weather or the outer environment is not safe, or fit for his survival.Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.
Therefore, The five categories of adaptations are migration, hibernation, dormancy, camouflage, astivation.

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. At the end of the experiment, there were 99/8 ounces of the solution remaining. How many ounces of solution did Mia start with? *
Given:
The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.
Remaining solution at the end of the experiment = [tex]\dfrac{99}{8}[/tex] ounces.
To find:
The initial amount of solution.
Solution:
Let the initial amount of the solution be x.
The solution decreased by [tex]\dfrac{9}{8}[/tex] ounces every hour for 5 hours.
Total decreased amount [tex]=\dfrac{9}{8}\times 5[/tex]
[tex]=\dfrac{45}{8}[/tex]
Initial amount = Remining amount + Decreased amount of solution.
[tex]x=\dfrac{99}{8}+\dfrac{45}{8}[/tex]
[tex]x=\dfrac{99+45}{8}[/tex]
[tex]x=\dfrac{144}{8}[/tex]
[tex]x=18[/tex]
Therefore, the initial amount of solution is 18 ounces.

asap!!! A researcher illuminated a filament of cyanobacteria with light that passed through a prism, thus exposing different segments of cyanobacteria to different wavelengths of light. He found that the bacteria in the green light changed in color from green to red after multiple weeks of exposure but were still reproducing at the same rate. What can you conclude about the change in pigmentation of the cyanobacteria exposed to green light?
1.) More chlorophyll a was produced in response to the green light exposure
2.) The cyanobacteria were dying and were changing color in response
3.) Red light instead of green light was being absorbed by the chloroplasts
4.) More red photosynthesis pigments were produced to absorb green light
Answer:
#4.. More red photosynthesis pigments were produced to absorb green light
Chlorophyll, carotenoids, and phycobiliproteins, as well as additional classes like scytonemin, which are more focused on cyanobacterial cells' protection, are the three main classes of photosynthetic pigments that stand out in cyanobacteria. Thus, option D is correct.
What are the characteristics of cyanobacteria?Many plants depend on cyanobacteria for their wellbeing and development.
Being able to transform inert atmospheric nitrogen into an organic form, like nitrate or ammonia, makes them one of the very few types of organisms that can do so.
Cyanobacteria are microscopic, photosynthetic organisms that are classified as bacteria.
They were once known as blue-green algae. Since dense growths frequently color water green, blue-green, or brownish-green, they were previously referred to as blue-green algae.
Therefore, More red photosynthesis pigments were produced to absorb green light.

Once amylase has broken down starch, can it break down another starch molecule?
Answer:
Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.
Explanation:
Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.
The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.
Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.

What is the initial source of the energy in all food webs and food chains? Explain please
Answer:
The sun
Explanation:
The sun provides the light energy that plants need in order to produce glucose the animals gain after eating the plants or the animals that ate the plants.
The initial and ultimate source of the energy in all types of food webs and food chains is the Sun.
What is the primary source of energy?The Sun is the major source of energy for living organisms and the ecosystems of which they are a part on the Earth. Producers are the organisms of the food chain which produce energy such as plants, algae, and cyanobacteria. These organisms use the energy from sunlight to make organic matter from that of carbon dioxide and water molecules. This establishes the beginning of energy flow through almost all the food webs.
The light which is coming from the sun allows the green plants that is the producers to manufacture chemical energy which fuels all the cellular functions. In turn once the plants are eaten, this chemical energy and nutrients are transferred to the consumers and to other higher organisms.

What is the difference between facilitated diffusion and active transport?
Facilitated diffusion uses ATP and moves substances with the concentration gradient; active transport does not.
Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
Active transport uses ATP and does not require a carrier protein; facilitated diffusion does neither.
Facilitated diffusion uses ATP and requires a carrier protein; active transport does not.
Answer:
Active transport uses ATP and moves substances against the concentration gradient; facilitated diffusion does not.
Explanation:
Active transports moves against the concentration gradient (hence why it needs energy or ATP to do so, its going "against the grain"). Facilitated diffusion does not require ATP but does something require carrier proteins during passive transport.
base on what you have learned from the previous activities, define speech context in your own words.
plsss help
Answer:
This refers to the condition, environment and or circumstance under which a speech or communication was made.
Explanation:
The context of a speech can significantly alter their meaning even though the body of the information has not changed. This is why understanding contexts are very crucial.
The context of a speech helps the receiver to make a decision about what to place importance on and about what, he or she can safely make assumptions about.
Some examples of communication contexts are:
Mass communicationIntrapersonal communicationInterpersonal communicationGroup communicationPublic communicationCheers
Speech context has to do with the circumstances that are available which affects the meaning of a speech.
There are three types of speech context which include:
Intrapersonal InterpersonalPublicAs a result of this, when a person is making a speech to either himself, one more person, or to a group of people, it is important to note that the audience is very important so that the message will be well received.
Interpersonal communication has to do with the communication between people you have a close relationship with.
Intrapersonal communication is the type of communication where a person talks to himself, usually loudly.
Public communication is the communication among a group of people.

an increase in the concentration of protons in the cytosol will most likely have which of the following effects on glycolysis
Answer:
Reaction rate will increase as a result of the increased H+ concentrate
Explanation:
Because the more ions the faster the reaction rate
The increase in the concentration of protons ; increases the Reaction rate
An increase in the number the positive ions ( H⁺ ) in a reaction will lead to an increase the reaction rate and a decrease in the activation energy.
Therefore as the number of protons ( H⁺ ) in the cytosol increases, the ripple effect it will have on glycolysis will be an increase in the rate of reaction ( i.e. Reaction rate ) and a decrease in activation energy.
Hence we can conclude that an increase in the concentration of protons in cytosol will increase the Reaction rate of glycolysis.
