Question 2
2.
The diagram represents the relationship between photosynthesis and cellular respiration. Drag the appropriate gas that used and produced in this diagram
Other Answer Choices:
oxygen
carbon dioxide

Question 3
3.

Select the level on the energy pyramid that has the most energy.

Question 4
4.

In which way are photosynthesis and cellular respiration different?

Question 5
5.

Base your answer to the following question on the passage below which describes an ecosystem in New York State and on your knowledge of biology.

The Pine Bush ecosystem near Albany, New York, is one of the last known habitats of the nearly extinct Karner Blue butterfly. The Karner Blue butterfly's larvae feed on the wild green plant, lupine. The larvae are in turn consumed by predatory wasps. The four groups below represent other organisms living in this ecosystem.


The Karner Blue larvae belong in which group?

Question 6
6.

Select the bond that holds the maximum amount of energy.

Question 7
7.

How can ADP be transformed into ATP?

Question 8
8.

Which statement is supported by the diagram?

Question 9
9.

Which of the following is not a factor that affects photosynthesis?

Question 10
10.

A potted plant is placed inside a clear, sealed vacuum container where no gases can get inside. The container has water pumped into it on a regular basis. The container is placed in the sun and the plant's growth is monitored. Which statement best describes what will most likely happen to the plant over time?

Question 11
11.
Fill in the formula for photosynthesis below.

6__________ + 6CO2 -----> __________ + 6__________
Question 12
12.

Mike has four aquatic plants of the same size and same species. He submerged the plants in a separate beaker filled with 200 ml of water. He then sets each beaker under a different intensity of light. Mike observes that, of the four plants, the plant with the beaker under the most intense light gives off the most gas bubbles in a 20-minute period. Which of the following statements best explains Mike's observations?

Question 13
13.

Two test tubes were filled with a solution of bromothymol blue. A student exhaled through a straw into each tube, and the bromothymol blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow.


Which statement best explains why the solution in the test tube placed in sunlight returned to a blue color?

Question 14
14.

Which of the following organism(s) performs cellular respiration?

Question 15
15.

What process releases energy from food molecules by producing ATP in the absence of oxygen?

Question 16
16.

A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles.

Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?

Question 17
17.

Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces alcohol and CO2. Which conclusion can be made from these observations?

The graph below shows the rate of alcoholic fermentation for yeast at different temperatures.

  • Autotrophs and Heterotrophs
  • Occurs in the Mitochondria
  • Requires Light Energy
  • Occurs in the Chloroplast
  • Autotrophs Only
  • Creates ATP
  • Photosynthesis
  • Cellular Respiration
Question 21
21.

Muscle cells are responsible for obtaining energy so the body can perform voluntary and involuntary movements. Using your knowledge about organelles and muscles, how would a muscle cell be different from other types of animal cells?

Question 22
22.

Question 26
26.
Green onions that are left in a dish of freshwater for several hours become stiff and remain standing upright. Therefore, the freshwater is __________because water is entering the cells to make them turgid (stiff). Similar green onions left in a saltwater solution become soft and wilt. The salt water is __________ because water is exiting the cells to make them flaccid (soft).
Question 27
27.

A specific type of cell is being studied by a scientist. She notices the cell contains a nucleus, lysosomes, a cell membrane, and a cell wall. What is the correct classification of this cell?

Question 28
28.

What molecule is released when water is split during the light-dependent reactions in photosynthesis?

Question 29
29.

During cellular respiration, which reaction produces the most ATP?

Question 30
30.

An advertisement for a health supplement for dogs claims to build lean muscle and strengthen tendons and ligaments, as well as provide short-term energy. Which two macromolecules must the supplement contain to provide these benefits?

Question 18
18.

According to the graph, what is the relationship between the rate of fermentation and temperature?

Question 19
19.

Which statement could explain the data shown in the graph?

Question 23
23.

Based on the graph, which process is occurring between minute 5 and minute 10?

Question 24
