A student drew this model to show the flow of convection currents
on Earth.
Part A
Is the model accurate? Explain your answer.
Answers
Answer:
Yes the model is correct
Explanation:
Transfer of heat energy takes place usually any of these three processes namely; Conduction, Convection and Radiation. In conduction, transfer of heat energy takes place by microscopic collisions of particles within a body. In radiation, heat, light and energy through any source is sent out from something and moves through space without a material medium of propagation. In Convection, heat transfer happens because of the movement of the bulk of molecules within fluids.
We can define convection currents as a natural process of heat transfer involving the movement of energy and heat from one place to another.
The equator is the part on Earth that is nearest to the sun hence it receives much heat. As a result of this, the air near the equator rises upwards as it becomes less dense and later spreads out and again descends towards the equator. This process is responsible for the continual circulation of air which is called wind. It is due to the process of atmospheric convection currents that the clouds are kept aloft.
From the foregoing, the model shown in the image has been validated as a correct model of convection current in nature.
Answer:The model accurately shows convection. However, these large convection currents would occur only if Earth did not rotate. Because Earth rotates, smaller convection cells form.

Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen windows, and one on the mantel in the living room. Each plant has the same pot and the same soil, and Lauren gives each plant the same amount of water. Which is the independent variable?
Answers
Answer:
First, before determining which variable is which, we go over the definition of each. The independent variable is the one which is intentionally changed in order to investigate its effect on the dependent variable. The dependent variable is monitored and changes occur in it due to the changing conditions of the independent variable. In this case, the location of the African violets is the independent variable as it is intentionally changed, while the rate of growth of the African violets is the dependent variable as it is being measured.

List 3 negative impacts does plastic pollution have on the ocean?
Answers
Ingestion
And suffocation
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

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.

s there any evidence of weathering, erosion or deposition? What is the evidence? What do weathering, erosion and deposition mean? About Culebra, Puerto Rico
Answers
Answer:
Erosion, weathering, and deposition are at work everywhere on Earth. Gravity pulls everything toward the center of Earth causing rock and other materials to move downhill. Water's movements (both on land and underground) cause weathering and erosion, which change the land's surface features and create underground formations.
The effects of these processes are as follows:
Changes in shape, size, and texture of land-forms (i.e. mountains, riverbeds, and beaches)
Landslides
Buildings, statues, and roads wearing away
Soil formation
Washes soil, pollutants, harmful sediments into waterways
Causes metals to rust
Reduces beaches, shorelines
Delta formation

How does passive transport come into play in oxygen's journey through our body?
Answers
In the alveoli of the lungs, oxygen frequently diffuses from the air into the erythrocytes and blood plasma.
What is passive transport?Diffusion is a form of passive transport where molecules migrate from a high concentration to a low concentration, if you didn't know. Therefore, it follows that the oxygen content of the air must be higher than that of the blood.
Passive membrane transport methods are the most direct. Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.
Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration.
Therefore, Passive transport is a term that refers to both osmosis and diffusion. They don't need any power.

how do creationists and evolutionists differ in their views of natural selection?
Answers
Answer: creationists believe in higher power to create things as is and evolutionists believe we originate from a common past and constantly change
Explanation: Creationists believe the belief that the universe and living organisms originate from specific acts of divine creation, as in the biblical account, rather than by natural processes such as evolution.
The theory of evolution is based on the idea that all species are related and gradually change over time. Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism.
Answer:
Creationists believe that natural selection is a God ordained process. Evolutionists believe that natural selection is a scientific process.

Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
:How does the height of an object affect the amount of mechanical energy it contains?
1:Variables What is the test variable?
Answers
The height of an object is crucial to the amount of energy something has because the higher up it is the most potential energy it has and kinetic energy it could have.
For example, if the height of a basketball was just a couple inches off the ground, it would not have a large amount of potential energy because because there is not much of a fall between the ball and the ground. However, if the ball was higher, there would be more potential energy because there is more room to fall.
---
"What is the test variable?"
The test variable, or independent variable in this case would be the height, as the scientist is changing the height in order to get different results in the total mechanical energy, which would be the dependent variable.

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.
