1. Which form of fermentation is used to produce beer?

• A. Lactic acid fermentation
• B. Acetic acid fermentation
• C. Propionic acid fermentation
• D. Ethyl alcohol fermentation

Correct answer: D

Rationale: The correct answer is D, Ethyl alcohol fermentation. During beer production, yeast metabolizes sugars in the wort to produce ethanol (ethyl alcohol) and carbon dioxide, which are responsible for the alcohol content and carbonation in beer. Choices A, B, and C are incorrect because lactic acid fermentation produces lactic acid, acetic acid fermentation produces acetic acid, and propionic acid fermentation produces propionic acid, none of which are used in the production of beer.

2. Select the cell parts that are present in plant cells but not animal cells (there may be more than one answer):

• A. Cell membrane
• B. Cell wall
• C. Ribosome
• D. Chloroplast

Correct answer: B

Rationale: Plant cells have a cell wall (B) which provides structural support and protection for the cell, a feature that is not present in animal cells. The cell membrane (A) is found in both plant and animal cells. Ribosomes (C) are present in both types of cells and are responsible for protein synthesis. Chloroplasts (D) are unique to plant cells and are responsible for carrying out photosynthesis. Therefore, the correct answers are B and D because the cell wall and chloroplast are specific to plant cells, while the cell membrane and ribosomes are found in both plant and animal cells.

3. If a test has poor internal consistency, which statement is true?

• A. The test produces different results at different times.
• B. The items do not correlate or measure similar things.
• C. The test produces different results depending on the researcher.
• D. The items never vary even when the test environment changes.

Correct answer: B

Rationale: Correct answer: If a test has poor internal consistency, it means that the items do not correlate or measure similar things. This lack of correlation indicates that the items in the test are not measuring the same underlying construct or concept, leading to unreliable results. Choice A is incorrect because poor internal consistency is not about producing different results at different times but rather about the lack of correlation among items. Choice C is incorrect because the issue lies within the test itself, not with different researchers. Choice D is incorrect because poor internal consistency implies that the items do vary in their measurement, contributing to the unreliability of the test.

4. In an example of a male with hemophilia and a female carrier, what ratio of the offspring is predicted to have the disease?

• A. 0 female : 2 males
• B. 1 female : 0 males
• C. 1 female : 2 males
• D. 2 females : 1 male

Correct answer: C

Rationale: In this scenario, the male offspring will inherit the hemophilia trait from their mother due to the sex-linked inheritance pattern. The female offspring will inherit one X chromosome from their mother, becoming carriers of hemophilia. Therefore, the predicted ratio of offspring with the disease would be 1 female as a carrier and 2 males with hemophilia. Choice A is incorrect because there would be male offspring with the disease. Choice B is incorrect as there would be male offspring with hemophilia. Choice D is incorrect as it does not reflect the inheritance pattern of hemophilia.

5. What type of cell is an animal cell?

• A. Prokaryotic
• B. Eukaryotic
• C. Plant Cell
• D. Bacterial Cell

Correct answer: B

Rationale: The correct answer is B, eukaryotic. Animal cells are classified as eukaryotic cells because they contain membrane-bound organelles such as the nucleus, mitochondria, and endoplasmic reticulum. Choice A, prokaryotic, is incorrect as prokaryotic cells lack membrane-bound organelles. Choice C, Plant Cell, is incorrect as the question specifically asks about animal cells. Choice D, Bacterial Cell, is incorrect as bacteria are prokaryotic cells.
