Answer:Ground
Explanation:The roots help soak up moisture fromthe ground and can also store extra food made from photosynthesis
Photosynthesis occurs and extra food is stored in ground plant tissues in the form of sugars.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Answer:
Chemical change
Explanation:
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.
its not physical change: What is a physical change? A physical change is a change to the physical—as opposed to chemical—properties of a substance. They are usually reversible. The physical properties of a substance include such characteristics as shape (volume and size), color, texture, flexibility, density, and mass.
its not chemical reaction: A chemical reaction is a process in which one or more substances, also called reactants, are converted to one or more different substances, known as products. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products

Answer:
75% straight
50% bent
Explanation:
because the Punnett Squares work that way
think of it as a multiplication table...when 2 numbers come to the middle, they give you the answer just like these squares (they're just smaller)
R + R = RR
R + r = Rr
R + r = Rr
r + r = rr
RR is 25%
Rr is 50% because there are 4 boxes and 2 of them is Rr
rr is 25%
Simpler answer:
I know because 25% + 50% = 75% for the straight root. 25% + 25% = 50% for the bent toot.
2. 1. Your best friend has missed a lot of school recently. Your teacher has allowed you to create a study guide and will let your friend use it on the test.
The guide should include:
• descriptions of amplitude, wavelength, frequency, and wave speed.
• Give examples of the wave relationship between amplitude and wavelength (if there is no relationship, explain how you know)
• Give examples of the wave relationship between wavelength and frequency (if there is no relationship, explain how you know)Text to speech
Answer:
Hi (best friend)! Here is what you missed!
Five wave parameters are defined and measured: the time, the frequency, the amplitude, the wavelength, and the speed. The wave length is the time it takes to pass a full phase. The frequency is just the opposite; it's the number of wave cycles that have been completed in a second.
Lets give a wave of water as an example. Its wavelength is the distance from crest to crest or from trough to trough. The wavelength can also be thought of as the distance a wave has traveled after one complete cycle—or one period. The time for one complete up-and-down motion is the simple water wave’s period T. In the figure, the wave itself moves to the right with a wave velocity vw. Its amplitude X is the distance between the resting position and the maximum displacement—either the crest or the trough—of the wave.

Define reactant.
Define product.
Define precipitate.
Answer:
Answers below!
Explanation:
Reactant- a substance that takes part in and undergoes change during a reaction.
Product- a substance produced during a natural, chemical, or manufacturing process.
Precipitate- 1. to separate from a solution as a precipitate. 2. to fall to the earth's surface as a condensed form of water; to rain, snow, hail, drizzle, etc.
Precipitate has different meanings so I didn't really know about which one, but tell me if I'm wrong :)
Answer:
Reactant: a substance that takes part in and undergoes change during a reaction.
Product: are the species formed from chemical reactions. During a chemical reaction reactants are transformed into products after passing through a high energy transition state.
Precipitate: a solid formed by a change in a solution, often due to a chemical reaction or change in temperature that decreases solubility of a solid

You will complete the following:
Part One: Experimental Design. Plan out an experiment by answering the guiding questions below.
Part Two: Design a Lab Report. Write the outline of a lab report so that another student could complete the experiment by using the materials listed below:
sand
water
heat lamps
thermometers
cups
Part One: Experimental Design
In this section, you will think about what type of experiment to set up. Remember, you are NOT completing the experiment, only designing it. If you want to review the scientific method first, use this tutorial. Use these guiding questions to help you design the experiment. Answer each question below:
What hypothesis will the experiment test?
What are the variables?
What purpose would the sand serve?
What purpose would the water serve?
What purpose would the heat lamps serve?
What purpose would the thermometers use?
How can you use these materials to test whether land or water heats faster?
How would you compare whether land or water heats faster?
Within a 24-hour period, at what three points should the temperature be taken? Why?
What would an effective conclusion need to include?
Part Two: Design a Lab Report
Once you have designed the experiment, you must write out the instructions so another student could act as the experimenter and follow them. Fill in the following elements of this lab report as described in italics below.

Identify the variables.
Write out your hypothesis in an if/then format.
Gather your materials.
Analyze the data.
Write your conclusion.
Data Analysis
Label a data table so that the experimenter can record observations for the sand and water temperatures at various points.
Conclusion
Explain what the experimenter should include in this section to show how the data proved the hypothesis.
Answer:
the ground would heat up slower than the sand because it has lots of moisture so sand would heat up faster than any thing other than lava
Explanation:
How is energy involved in physical change?
During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants.
Why do physical properties change?
Answer:
Physical change takes place without any changes in molecular composition.
