Emily and Vicky are discussing coal as an energy source. Emily claims coal is a renewable energy source. Vicky disagrees.
Who is right, and why?
Vicky; coal is a fossil fuel and supplies on Earth are limited.
Emily; coal burns cleanly, producing only carbon dioxide and water.
Emily; renewable resources are always gases or liquids.
Vicky; it is possible to replenish coal in the short term.
Answers
Answer:
Vicky is right, and Emily is incorrect.
Explanation:
Coal is not a renewable energy source because it is a fossil fuel. Fossil fuels are formed over millions of years from the remains of dead plants and animals. These resources are finite, and their reserves on Earth are limited. Once these resources are depleted, they cannot be replenished in a reasonable timeframe.
Explanation:
Fossil fuels such as coal can not be reproduced from the heat coming from them once coal is burned it is gone it can’t be renewed
A student wants to find out if the amount of bleach has an effect on stain removal.
He plans to use two white shirts, stain each of them with mustard, and then wash each of them using bleach. He can change the size of the stain on the shirt and the amount of bleach he adds to the water.
Which test should the student set up?
Answers
Answer:
The second option.
Explanation:
We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.
The 2nd option uses different amounts of bleach to clean the same amount of stain.
If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.
It's not an effective way to see if the amount of bleach has an effect on stain removal.

Observation
Use your senses to make an observation about your environment.
Questions
Create a hypothesis that can be tested in an experiment.
Remember, a hypothesis has a specific "if then" wording.It describes what will happen to the dependent variable when changes are made to the independent variable.For example, "If a plant is fertilized (independent variable), then it will grow faster (dependent variable)."
Design and plan an experiment.
Be sure to identify an independent variable, a dependent variable, and any controls.Remember, controls are factors which stay the same.In an experiment designed to test the previously stated hypothesis, one control would be to use the same kind of plant.Write a complete description of your experiment.Include a list of necessary materials.It is a good idea to follow a step-by-step procedure format.Think of everything you need to do, then write it down in the order it must be completed.Your description and procedure should be clear enough that another person could duplicate your experiment exactly.
Answers
Answer: E
Explanation:
Experiment Design:
Independent Variable: Intensity of light (Low, Medium, High)
Dependent Variable: Rate of photosynthesis (measured by oxygen production or CO2 consumption)
Control: Same kind of plant, constant temperature, constant CO2 concentration, constant water availability, and constant duration of light exposure.
Materials:
Three identical potted plants (of the same species)
Light source(s) with adjustable intensity
Light meter (lux meter) to measure light intensity
CO2 gas sensor or oxygen gas sensor
Timer or stopwatch
Water supply
Thermometer
Data recording sheets
Procedure:
Set up the three identical potted plants in a controlled environment with the same temperature and CO2 concentration.
Ensure that all plants receive the same amount of water.
Place the light source(s) at an equal distance from the plants.
Measure and record the initial light intensity using the lux meter.
Adjust the light intensity to low for the first plant, medium for the second plant, and high for the third plant.
Start the timer and expose the plants to light for a specified duration (e.g., 1 hour).
During the exposure period, measure and record the temperature, CO2 concentration (if possible), and light intensity at regular intervals.
After the exposure period, use the CO2 gas sensor or oxygen gas sensor to measure the change in CO2 concentration or oxygen production, respectively, in the surrounding air.
Record the data obtained from the sensors and calculate the rate of photosynthesis for each plant.
Repeat the experiment multiple times to ensure reliability and average the results.
Analyze the data collected and compare the rates of photosynthesis among the three different light intensities.
Draw conclusions based on the analysis and determine whether the hypothesis is supported or rejected.
By following this experimental design, you can test the hypothesis and determine the effect of light intensity on the rate of photosynthesis in plants. Remember to conduct the experiment in a controlled environment and gather sufficient data for accurate analysis.

Which substance is a compound?
water

Answers
Answer:
Water
Explanation:
This is actually a chemistry question but I'll answer it anyways
The definition of a chemical compound is " a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. "
Compounds are homogenous, which means that they are evenly distributed and have 2 or more different elements from the definition
Therefore the answer is that water is a compound as its chemical make up is H2O.
Gold is made up of 1 element
Oxygen is made up of 1 element,
Hydrogen is made up of 1 element
Therefore these options are not viable since they do not contain 2 or more elements.
Water is a compound.
A compound is a substance that results from a combination of two or more different chemical element.Here these two elements are Hydrogen and oxygen.What are examples of common household compound?Water.

A pedigree chart is used to _______.

predict genotypic probabilities
track inherited traits through generations

Answers
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.
