Data Collection: Pinky’s science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder. Fun Fact: There are free “cricket chirp calculators” online you can explore, which didn’t exist freely online when Pinky was in junior high. Consider if data was collected consisting of the average number of cricket chirps at different temperatures in her backyard. 10. Which variable would be an independent variable?
Answer:
Different temperatures in her backyard
Explanation:
The independent variable would be the different temperatures in Pinky's backyard.
The independent variable is a variable whose value is not affected by another variable during research. It is a variable that directly affects the actual variable that is measured - the dependent variable. The independent variable is usually varied in order to see the kind of effect it will produce on the dependent variable.
In the case of Pinky, the different temperature at the backyard affects the number of cricket chirps. Hence, the temperature is considered the independent variable while the number of cricket chirp is considered the dependent variable.

Answer:
Group A
Explanation:
Answer:
C. Group A
Explanation:
First, let's define accuracy and precision.
Precision: the measurements are all close to each other
Accuracy: the measurements are close to the true value.
Let's examine the answer choices.
A. Group C: 32.1 g, 35.0 g, 25.0 g
This is not accurate or precise. The measurements are far from each other and only one is close to 25 g.
B. Group D: 20.0 g, 25.0 g, 30.0 g,
The measurements are relatively accurate and precise. They are within 5.0 grams of each other and the true value.
C. Group A: 28.5 g, 28.4 g, 28.5
The measurements are the most precise. They are all within 0.1 gram of each other. They are also somewhat accurate.
D. Group B: 25.5 g, 25.0 g, 24.8 g
The measurements are not precise or accurate. There is one measurement that is far from the true value and the other measurements.
Therefore, the most precise measurements are from Group A.

Imagine that you wish to compare two different diets that will be fed to tadpoles raised in a lab. One diet is a meat-based fish food, and the other is the traditional diet of boiled lettuce. You want to see if the meat-based diet will be associated with an increase in the average weight of the tadpoles. In your experiment you keep all other factors, such as tadpole density per pan, temperature, pH, and the amount of food the same. The only difference between your control and experimental groups is the type of food the tadpoles receive. What is the independent variable for the tadpole diet experiment?
Answer:
TYPE OF DIET
Explanation:
Independent variable of an experiment is that variable that is subject to manipulation or changing by the experimenter in order to effect a response in the dependent variable.
According to the experiment in this question, the type of diet is changed for different groups of tadpoles in order to see the effect on their average weight. Based on this, the independent/manipulated variable is the TYPE OF DIET administered to each group of tadpole while the growth (average weight) of the tadpoles is the dependent variable.

A solution of one part of egg albumen mixed with two parts of water in a test tube is used to test for what?
Answer:
It is a test to check the protein's solubility.
Explanation:
Proteins have varying levels of solubility and it is necessary to carry out tests that prove in which aqueous media the proteins are more likely to have high levels of solubility. This facilitates the execution of scientific works that develop products that work with proteins.
The level of solubility of proteins depends on the distribution of the polar and nonpolar groups of this molecule.
The most common test is done by adding water and protein to a beaker. An example of this is done by adding part of egg albumin mixed with two parts of water.

1. For each missing word or phrase, circle the choice that correctly completes the sentence. The three main gases that trap heat in Earth's atmosphere are (carbon dioxide / oxygen / nitrogen / hydrogen), methane, and water vapor. They contribute to the (climate / ecosystem / greenhouse / biosphere) effect, which makes Earth's temperatures warmer than they would be otherwise.
Answer:
Carbon Dioxide; Greenhouse
Explanation:
Carbon dioxide, methane, and water vapor all trap heat in the Earth's atmosphere. Because they are trapping the gasses in the atmosphere, they are contributing to the Greenhouse effect, which makes Earth's temperatures hotter/warmer. The "Greenhouse" part is saying that everything underneath the Earth's atmosphere is "housing" the heat and keeping the heat in.
In nature, mutation rates are usually ______ to maintain alleles that are not favored in a population by natural selection.
In nature, mutation rates aren't usually high enough to maintain alleles that are not favored in a population by natural selection.
While in the wild, many populations are led by natural selection. This means that favorable traits are passed down through generations, while unfavorable traits are not. Traits that are best suited for the environment of the organism will prevail to help the chance of survival.
Mutation rates usually aren't high enough to create traits that are unfavorable to an organism. While mutations are still possible, it is still unlikely. The traits that are chosen by natural selection are most likely to be passed onto organisms and their offspring.

What is a stimulus? What is homeostasis? How are irritability and homeostasis related? Describe an example of homeostasis, response and adaptation in a living organism.
Answer:
All is in order.......
stimulus is a thing or event that evokes a specific functional reaction in an organ or tissue.
homeostasis is the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.
Irritability is that characteristic of living organisms in being aware of, and being able to respond to, a stimulus which tends to disturb the steady state or homeostasis which all organisms prefer for maintaining life.
Humans' internal body temperature is a great example of homeostasis. When someone is healthy, their body maintains a temperature close to 98.6 degrees Fahrenheit (37 degrees Celsius). Being warm-blooded creatures, humans can increase or decrease temperature internally to keep it at a desirable level.

The nucleolus __________. The nucleolus __________. assembles ribosomes synthesizes ATP stores chromatin synthesizes proteins
Answer:
The correct answer is: assembles ribosomes.
Explanation:
The nucleolus is the largest structure in the nucleus of a cell body, granular, and round structure. The nucleolus is made up of components like RNA and proteins In the center of the nucleus of a cell.
This is associated with the synthesis of ribosomes and the formation of the rRNA or ribosomal RNA. The ribosomal RNA and proteins combine together to form subunits of the ribosomes that are move out of the nucleus to the cytoplasm in order to perform their function.
Thus, the correct answer is: assembles ribosomes.

PLZ HELP :) The light dependent and light independent reactions of photosynthesis work together. The light-dependent reactions trap the energy from sunlight to form ATP and NADPH molecules, giving off oxygen gas. The light-independent reactions use that chemical energy and carbon dioxide to build stable long-term energy storage in the form of:
Group of answer choices
glucose
ATP
water
proteins
The answer is A. Glucose.
Short answer, I had the same question on a quiz.
Long answer, the second phase, AKA the light-INdependent or Calvin Phase, uses that ATP & NADPH from the light-dependent phase & forms glucose to provide long-term energy for the cell to use.
Hope this helps! :)
The light-independent reactions of photosynthesis use the chemical energy in the form of ATP and NADPH, produced by the light-dependent reactions, along with carbon dioxide to build stable, long-term energy storage in the form of glucose. Therefore, the correct option is (A).
What is light-independent reactions?The light-independent reactions, also known as the Calvin cycle, is the second stage of photosynthesis that takes place in the stroma of the chloroplasts in plants. It is named light-independent because it does not require light energy directly, but it does depend on the products of the light-dependent reactions, which are ATP and NADPH.
In the light-independent reactions, carbon dioxide from the atmosphere is fixed into organic molecules using the chemical energy in ATP and NADPH. The first step of the cycle is carbon fixation, where carbon dioxide is combined with a 5-carbon molecule called ribulose-1,5-bisphosphate (RuBP) to form a 6-carbon intermediate, which immediately breaks down into two 3-carbon molecules called 3-phosphoglycerate (3PG). The second step of the cycle is reduction, where ATP and NADPH are used to convert the 3PG into G3P (glyceraldehyde-3-phosphate). Some of the G3P molecules are used to regenerate RuBP, while the remaining G3P molecules can be used to make glucose, sucrose, or other organic molecules.
