In a randomized trial, scientist try to make sure that there is only one difference between the two groups. What do we call all the things that are the SAME Between the two groups?

A. Predictions
B. Controls
C. Constant
D. Variables

Answers

Answer 1

Hey there! I'm happy to help!

A. Predictions are guesses you make about the result of a trial. Let's say that you want to test what will happen if you put less eggs into a cookie recipe. You could make a prediction that the cookies will be more crumbly. This is not the term for things that are the same between two groups, so this is incorrect.

B. Controls are a type of variable that isn't influenced in a unique way as part of the experiment. This is to be able to compare the things you change to a thing that hasn't changed. With our cookie example, a control group would just be a cookie recipe with the normal amount of eggs. Then we can compare a normal cookie to one with less eggs. We see that a control is a type of group, and not a specific thing that is similar or different between the groups, so this is incorrect.

D. Variables are things that  can change or vary in your experiment. There are independent variables, which are things that you change, such as the number of eggs in the recipe. Then, you have dependent variables such as color, texture, taste, etc. However, these can change depending on the group because the number of eggs could switch, so this is the wrong term and incorrect.

C. Constants are things that you do not change as part of your experiment. You do not change these variables. In our case, the constants will be all of the other ingredients like the amount of flour, milk, water, sugar, etc. If we have a control group and a group with less eggs, these things will remain constant in both of them. So these things are the same between the two groups, so this answer is correct.

We call the things that are the same between the two groups C. constants.

Have a wonderful day and keep on learning! :D

what is Monosaccharide?

Answers

Answer:

A Monosaccharide is just the simplest form of sugar. It's general term applied to a sugar that cannot be broken down into anything 'simpler'. A great example of this is glucose. Glucose cannot be hydrolized to form anything else, but there are more complex forms of glucose like glycogen. Glycogen is basically a bunch of glucose molecules bonded together and used as "stored glucose", but glycogen can be hydrolized to form individual glucose molecules (monosaccharides).

Monosaccharides, also called simple sugars, are the simplest form of sugar and the most basic units of carbohydrates. The general formula is C ₙH ₂ₙO ₙ, or [Cnn] or { CH2O}n albeit not all molecules fitting this formula are carbohydrates. They are usually colorless, water-soluble, and crystalline solids.

Which of the following is not a testable hypothesis that this data could be used to support or disprove?

Answers

Answer:

b

Explanation:

this is because babies needs certain nutrient to grow faster which includes tallness

The statement that is not a testable hypothesis based on the given data is: being taller is always better than being shorter. Therefore option A is correct.

The given data provides information about the average height of females and males in different age groups. Let's analyze each statement to determine whether it is a testable hypothesis or not:

A. All men who are married are taller than their wives.

This statement cannot be tested using the given data because it only provides average heights for different age groups, but it doesn't provide any information about marital status or the specific heights of individual men and women.

Therefore, we cannot determine whether all married men are taller than their wives based on this data.

B. Height is affected by childhood nutrition.

This statement can be tested using the given data. By examining the average height changes across different age groups, we can infer whether childhood nutrition has an impact on height.

If there is a noticeable trend of increasing height from birth to older age groups, it could suggest a correlation between childhood nutrition and height.

C. Being taller is always better than being shorter.

This statement is subjective and cannot be tested using the given data. It is a matter of personal opinion and values, rather than something that can be objectively measured or proven.

D. All females are taller than males at age 12.

This statement can be tested using the given data. By looking at the average heights of females and males at age 12, we can determine whether females are, on average, taller than males at that specific age.

On a graph, the vertical axis is
the y-axis and the horizontal
axis is the x-axis. Onəwhat axis
should the INDEPENDENT
VARIABLE be placed?
A
on the vertical or y-axis
B
on the horizontal or x-axis

Answers

Answer:

x-axis

Explanation:

you control those values/variables

On a cartesian plane, the independent variable belongs on the x-axis.

What are coordinates?

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

The independent variable is the variable that is being manipulated or controlled in an experiment, and its values are typically plotted along the horizontal or x-axis.

The dependent variable, which is the variable being measured or observed in response to changes in the independent variable, is usually plotted on the vertical or y-axis.

This convention allows us to easily visualize and analyze the relationship between the two variables.

therefore, The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

how the consumers in one level of the pyramid obtain energy from the organisms at the previous level of the pyramid

Answers

Answer:

by feeding on the organism on the previous level, the consumers at each level will receive energy. However, most of the energy is lost at each trophic level and very little gets transferred from one trophic level to another. Approximately, 10% of the energy is transferred from one trophic level to another.

Explanation:

hence, when a level takes energy from a previous level, the engery transfers but slowly gets less, so some levels get less energy depending on where the engery was located.
