Please solve this lab reportJohn had a science fair project that he needed to do. He wanted to test the effects that organic and

chemical fertilizers had on plant growth. John predicted that the organic fertilizer would make the plants grow taller. He used three pots, three of the same type of seed, soil, organic fertilizer, chemical fertilizer, water, and a ruler. John put soil in the pots. He added chemical fertilizer to the first pot, organic fertilizer in the second pot, and no fertilizer in the third pot. He then planted one seed in each pot. John had to water the pots daily. He also checked for growth and took measurements for a period of 10 days. He measured the height of the plants.

Answer:

This question is incomplete; the complete part is: what are the independent, dependent, and controlled variables?

Independent variable: ORGANIC AND CHEMICAL FERTILIZERS

Dependent variable: HEIGHT OF PLANT

Controlled variable: Same type of seed, water

Explanation:

Independent variable is the variable that is changed or manipulated by the experimenter. In this question, John wanted to test the effects that organic and chemical fertilizers had on plant growth. Hence, the independent variable is the ORGANIC AND CHEMICAL FERTILIZERS used.

Dependent variable is the variable that responds to changes made to the independent variable. The dependent variable is the variable that is measured in an experiment. In this case, the HEIGHT OF PLANTS MEASURED is the dependent variable.

Controlled variable or Constant is the variable that is kept unchanged throughout the experiment in order not to influence the experimental result or outcome. In this case, the controlled variable is the SAME TYPE OF SEED USED, WATER.

How important is your skin for the functioning of the nervous system?
White raven [17]

Answer:

The skin is very important for the functioning of the nervous system, this is because, it serves as the sensory organ, which transmit the sense of touch to the brain for interpretation. The skin acts as the receptors of stimuli that are coming from outside of the body. For instance, if one mistakenly touch an hot pot with a bare hand, one will quickly remove the hand immediately. This is because the skin was able to sense the touch of hotness and send the information to the brain for the correct interpretation of the stimuli. Therefore, without the skin, the functioning of the nervous system will be impaired.

Explain: What conditions exist in space that are not suitable for humans or delicate machines?
natali 33 [55]

Answer:

First of all, The average temperature of outer space near Earth is 283.32 kelvins (10.17 degrees Celsius or 50.3 degrees Fahrenheit). In empty, interstellar space, the temperature is just 3 kelvins, not much above absolute zero, which is the coldest anything can ever get. Also, space is a vacuum, which means that you would suffocate. Space's environment is also very radioactive. Also, there is no pressure in space, So you would boil, fry, suffocate, and explode at the same time. Suits must be provided to create a safe environment in space.

Why don’t eclipses occur during any other moon phases besides the new and full moon?
Bad White [126]

Answer:

There's no eclipse at every full moon and new moon because the moon's orbit is inclined to Earth's orbit by about five degrees. Most of the time, the sun, Earth and moon don't line up precisely enough to cause an eclipse.

Explanation:

During a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface.

A young man develops skin cancer that does not spread to any other tissues. The mutation responsible for the cancer arose in a s
schepotkina [342]

Answer:

4. None of the man's children will inherit the mutation

Explanation:

This is because the mutation is somatic. that is it only affect  single  skin tissues  and not  carried in the sex-cells,that is not germinal.

Only Germinal mutation that are carried in the sex-cells of either sperm or  egg , and transmitted during fertilisation can be  be inherited by the offspring.

However, had it mean it was no localized, but metastasis,( spread through the blood stream to the  sex-cells,) then it can be inherited by the children. Besides the wife is also negative there is no chance of the kids inheriting  the mutation
