Biology Regents MIDTERM REVIEW Name _____________________________

Examine the diagram to the right. Use the information shown and your knowledge of biology to answer the following questions.

1. Name one substance in the diagram below that would have a net movement out of the cell. Explain.

2. Explain why the proteins will not diffuse into the cell.

Use the diagrams below and your knowledge of biology to answer the next two questions.

A student prepared a wet-mount slide of red onion skin and observed it under high power of a compound light microscope (view A). After adding a substance to the slide and waiting one minute, the student observed that there were changes in the cells (view B).

1. Identify one substance that could have been added to the cells on the slide in view A that would make them resemble the cells observed in view B.

2. Identify the specific substance that diffused to cause the change in appearance from view A to view B.

Base your answer to the next question on this diagram of the cell and your knowledge of biology.

1. Identify the cell as either a plant cell or an animal cell, and name two parts of the cell as evidence.

2. Is this cell prokaryotic or eukaryotic? Explain.

Base your answer to the following question on the diagram below and your knowledge of biology.

1. Identify the two body systems shown above and explain how they interact to maintain homeostasis.

A B

Use your understanding of dichotomous keys and the Key to Mosquito Genera determine the species of the insect below.

1. By using the key to the left, determine the gender (sex) of this mosquito.

2. By using the key above, determine the Genus to which this mosquito belongs.

1. What piece of lab equipment is this student using? Describe one proper usage technique that she should follow while using it.

The diagram to the right represents two cells next to a metric measuring device under the low power objective of a compound light microscope. What is the approximate length of a nucleus of one of these cells?

1) 100 μm

2) 500 μm

3) 1,000 μm

4) 1,500 μm

Use the information below and your knowledge of biology to answer the following questions.

Many people become infected with the chicken pox virus during childhood. After recovering from chicken pox, these people are usually immune to the disease for the rest of their lives. However, they may still be infected by viruses that cause other diseases, such as measles.

Discuss the immune response to the chicken pox virus. Explain the following:

1. The role of white blood cells in the body’s response to the virus

2. An explanation of why recovery from an infection with the chicken pox virus will not protect a person from getting a different disease, such as measles

An investigation was carried out and the results are shown below. Substance X resulted from a metabolic process that produces ATP in yeast (a single-celled fungus).

1. What metabolic process is being studied in this experiment?

2. What is substance X?

3. What piece of lab equipment is being used?

Base your answers to the next two questions on the diagram to the right and on your knowledge of biology.

1. Which statement best describes the diagram?

1) Nerve cell X is releasing receptor molecules.

2) Nerve cell Y is signaling nerve cell X.

3) Nerve cell X is attaching to nerve cell Y.

4) Nerve cell Y contains receptor molecules for substance A.

2. A drug is developed that, due to its molecular shape, blocks the action of substance A. Illustrate what this drug may look like.

Base your answers to the next two questions on the information and diagrams below and on your knowledge of biology.

The laboratory setups represented below were used to investigate the effect of temperature on cellular respiration in yeast (a single-celled organism). Each of two flasks containing equal amounts of a yeast-glucose solution was submerged in a water bath, one kept at 20°C and one kept at 35°C. The number of gas bubbles released from the glass tube in each setup was observed and the results were recorded every 5 minutes for a period of 25 minutes. The data are summarized in the table below.

1. State one relationship between temperature and the rate of gas production in yeast.

2. Identify the independent variable in this experiment.

Base your answers to the next two questions on the diagram to

the right and your knowledge of biology.

1. Identify the organ labeled X. What two body systems is it part of?

2. The dashed line in the diagram represents

(1) a digestive process

(2) a feedback mechanism

(3) cellular differentiation

(4) recycling of organic chemicals

Base your answers to the next 2 questions on the diagram below and your knowledge of biology.

Starches (or polysaccharides) provide the human body with energy. Before they can be transported to the body cells and used in the process of respiration, they must be digested. Please respond to the following:

1. Using the diagram above, where does the digestion of starches begin? Where does it end?

2. What enzyme breaks down starch?

3. What substance can be used as an indicator to determine if starch is present?
