2. I Love Popcorn!
Jason wanted to find out how he could increase the number of popcorn kernels that pop when
1
cooked. He hypothesized that more kernels would pop if he used more oil. To test this, he placed
100 kernels of "Pop Rite' popcorn into a popcorn popper that contained different amounts of oil. He
used the following amounts of oil: 5 ml, 10 ml, 20 ml, and 30ml. He used 5 ml of oil as the control.
Header
He conducted the test 3 times for each amount of oil. He then counted the number of kernels that
had popped. Each time he heated the oil for 2 minutes and cooked the popcorn for 4 minutes.
Hypothesis: I think the popcorn with the most oil will have the most popped kernels because the hotter
all the oil gets and the more oil there is in it, then the kernels will be able to pop faster. What are the:
Independent Variables:
Dependent Variables:
Controlled Variables:

Answers

Answer:

Independent: amounts of oil

Dependent: amounts of popped kernels

Controlled variables: Kernel brand, cooking time, popping time

Explanation:

Independent variables are what are changed in the experiment. The dependent variables depend on the independent so they are what is affected each time. Usually this is what is being tested for. Controlled variables are those that aren't being tested and are kept the same each time to make sure it doesn't change the outcome.

What would happen if a plant cell is placed in a solution of salt?

Answers

If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it. The loss of water from this movement causes plant cells to shrink and wilt. This is why salt can kill plants; it leaches the water from the cells.

Which is the most complete list of the parts of an experiment presented in this scenario? independent variable, dependent variable control group, experimental group, dependent variable independent variable, control group, experimental group control group, experimental group

Answers

Answer:

The answer is the second option: Dependent variable, experimental group and control group

Explanation:

Let's list out all possible variables/groups in the option

Independent variable: This is a variable that is intentionally (directly or indirectly) altered by the one doing the experiment but is not affected by any variable/group during the course of the experiment. No Independent variable was mentioned.

Dependent variable: This is a variable that is affected by another variable and is usually the variable been tested during the course of an experiment. The dependent variable here is the effectiveness of a new nutrient supplement.

Experimental group: This is the group that is being treated during the course of an experiment. The experimental group here is the group of identical mice given the supplement.

Control group: This is a reference group that is not given any treatment during the course of an experiment. The control group here is the group of identical mice not given anything.

From the above description, it can be deduced that the parts of the experiment described in the scenario in the question is dependent variable, experimental group and control group.

1. Was the restoration project effective? Explain why or why not, supporting your answer with information from your data tables and graphs. 2. Why was counting the number of species in the area important? In your answer, consider the effect a mangrove habitat has on biodiversity. 3. After five years, the average height of each mangrove species was also measured. Did this information help you better evaluate the success of the restoration project, or did it change your mind? Explain your reasoning.

Answers

Answer:

1-  Yes the restoration was effective because the north beach seeds were replant and in 5 years there was almost 100% regrowth of mangroves. After five years, the average height of each mangrove species was also measured.

2- Yes the counting the number of species in the area was important because it helped figure out how much the storm damaged each beach and it showed how the animals were affected. The effect a mangrove habitat has on biodiversity is by giving animals a home, a place to sleep and shelter.

3- Yes, after five years, the average height of each mangrove species was also measured which helped realize that the restoration project was a success.

What is aerobic respiration?

Answers

Explanation:

The respiration which uses oxygen is called aerobic respiration. In aerobic respiration, the glucose food is completely broken down into carbon dioxide and water by oxidation. Aerobic respiration produces a considerable amount of energy for use by the organism which gets stored in the ATP molecules.

Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. Most eukaryotes and prokaryotes use aerobic respiration to obtain energy from glucose.

6. Alex wanted to find out what toothpaste made teeth the cleanest. Everyday she brushed her teeth with a different product and then took a plaque test to see how much plaque was left. She used Crest, Colgate, Close-up, and water. a. Independent Variable (IV): ______________________________________________ b. Dependent Variable (DV): ______________________________________________ c. Control: _____________________________________________________________ d. Constants:__________________

Answers

Answer:

Independent variable: Different products of toothpaste

Dependent variable: Amount of plaque left in her teeth

Control group: Water

Constant: Same amount of time for product to have an effect

Explanation:

Independent variable is the variable that is subject to manipulation or change by the experimenter in order to effect a measurable response. The independent variable in this experiment is the DIFFERENT PRODUCTS OF TOOTHPASTE USED.

The dependent variable is the variable that is measured during the experiment. In this experiment, the dependent variable is the AMOUNT OF PLAQUE LEFT IN ALEX'S TEETH.

The control group in an experiment is the group that does not receive the treatment/independent variable. In this case, the usage of WATER is the control.

The constant is the variable kept the same for all the groups in the experiment. In the case, the Same amount of time for each product to have an effect on her teeth is the CONSTANT.
