biology
What don't you understand? I'll take a guess. If the independent variable was various amounts of a drug being given, then this would need to be measured along with the dependent variable. If the independent variable was either the presence or absence of a variable, the...

biology
Yes to all. However, when the independent variable is changed, it might also be measured to compare to the changes in the dependent variable.

science
If scientists do not agree with each other, they may replicate experiments to check the conclusions.

Science
Animals and protozoa do not have cell walls.

Since this is not my area of expertise, I searched Google under the key words "sequence of the stop codon" to get these possible sources: https://www.google.com/search?client=safari&rls=en&q=sequence+of+the+stop+codon&ie=UTF-8&oe=UTF-8 In the future, you can find the...

Z score is your score in arms of standard deviations. Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability (.6140) related to the Z score. Are you assuming that the scores are equal...

An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable. A dependent variable is the response or measure of results. Extraneous variables — other than the independent ...

Science (?)
More information needed. Do the rabbits have the same parents? Are the genes for either color dominate or recessive?

Science
Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you. See your later post.

What figure?

Statistics

math
(2x + 4y) * 3y = 6xy + 12y^2 (2x + 4y) * 8x = 16x^2 + 32xy Combine.

Math (?)
Your information is not accurate. Online "^" is used to indicate and exponent, e.g., x^2 = x squared. 14 r^5 would not give a decimal.

statistics
Either-or probabilities are found by adding the individual probabilities. .23 + .05 = ?

statistics
If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events. .6 * (1-.6) = ?

Since both genes (dominant) from one parent are for normal development, the chances for any child are 50% to be a carrier, but none will have the disease.

An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable. A dependent variable is the response or measure of results.

An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable. A dependent variable is the response or measure of results. It sounds like a classical experiment.

In classical conditioning, the unconditoned stimulus (US) is one which reflexively causes a response. One example is putting something into your mouth causes salivation. In this case the unconditioned response (UR) is the response to a US presented alone, the salivation. A con...

From your description, I'm not sure what is being asked. If it is "either blue or green," you are right. If it is just green ("green notepad is selected"), then 1/4 is correct.
