1. the diagram below represents a cell process. which statement regarding this process is correct? 1) cell B contains the same genetic information that cells A and C contain 2) cell C has DNA that is only 50 % identical to cell B 3) cell A has DNA that is only 75% identical to cell B 4) cells A, B & C contain completely different genetic information [correct choice : choice 1] Why??? the correct choice is A because it displays the process of mitosis which results in 2 identical daughter cells. Why you might get it wrong??? Because of the diagram it looks like B&C might have 50% genetic info from A because they are split in 2

2. A science researcher is reviewing another scientist experiment and conclusion. The review of the most likely consider the invalid if 1) the sample size produced is a great deal of data 2) other individuals are able to duplicate the results 3) it contains conclusions that are not explained by the evidence given 4) the hypothesis is not supported by the data obtained [correct choice: choice 3] Why??? the correct choice is 3 because in an experiment your conclusion must be supported by the data you received Why you might get it wrong??? because some people may think that your experiment is invalid if the data doesn't support the hypothesis section 13.1 pg 339

3. 1) 1 2) 2 3) 3 4) 4 [correct choice: choice 3] why? because amino acids are the building blocks of protein and enzymes are proteins why might you get it wrong? because you might not know the building blocks of substances
 * row || building blocks || substance synthesized using the building blocks ||
 * (1) || glucose molecules || DNA ||
 * (2) || simple sugars || protein ||
 * (3) || amino acids || enzyme ||
 * (4) || molecular bases || starch ||

4. Hereditary information is stored inside the 1)ribosomes, which have chromosomes that contain many genes 2) ribosomes, which have genes that contain many chromosomes 3) nucleus which has chromosomes that contain many genes 4) nucleus which have genes that contain many chromosomes [correct choice: choice 3] Why? genes are located on the chromosomes which is in the nucleus why you might get it wrong? you don't where the information is located

5. Every single-celled organism is able to survive because is carries out 1) metabolic activities 2) autotrophic nutrition 3) heterotrophic nutrition 4) sexual reproduction
