Which of the following would be considered a source of error in an experiment?A. Laboratory mice are similar but not identical to each other.
B. A student makes a mistake when measuring volume.
C. The hypothesis was unrelated to the research question.
D. Temperature readings are made late in the day, when everyone is tired and eager to go home.

Answers

Answer 1

Answer: D. Temperature readings are made late in the day, when everyone is tired and eager to go home.

Errors are what makes your measurement invalid and unreliable. There are two types of error which is called the systematic error and the random error. Each error has different sources. Words that were mentioned –invalid and unreliable are very important key aspects to determine that your measure is truly accurate and consistent. Some would recommend using the mean method, doing three trials in measuring and getting their mean, in response to this problem.

Which of the following is the correct matching nucleotide sequence for GATAC?

Answers

The correct matching nucleotide sequence for GATAC is CTATG.

What is nucleotide sequence?

The code for DNA is transcribed into mRNA, this process is called transcription. Nucleotide acid sequence is a succession of letters that indicate the order of nucleotides within a DNA.

DNA is a double stranded structure. The DNA is transcribed in mRNA this process is called transcription. DNA has base pairs. Adenine base pairs with thymine and guanine base pairs with cytosine.

In mRNA, G is replaces with C, A is replaced with T, T is replaces with A and A is replaces with T. When RNA forms protein is called translation. In biological system all the organisms transfer information in the form of nucleotides.

The correct matching nucleotide sequence for GATAC is CTATG.

How much sperm does it take to make a baby?

Answers

it just takes one sperm cell to go into the female egg to then produce a baby

Actually, only one sperm gets fertilised and develops into a baby. But a lot more sperms are required to carry out reproduction. This is because it is not sure if one sperm definitely gets fertilised. Some weaker sperms perish. The strongest sperm among the numerous sperms get fertilised while the others perish.
