The diagram below represents what occurred when an onion cell and a red blood cell were placed in distilled water. The best explanation for why the onion cells do not burst, while red blood cells often do, is that

the red blood cells have only a cell membrane, which does not protect them from bursting

the onion cells do not have a cell wall that could protect them from bursting

the onion cells have a cell membrane, which can protect them from bursting

the red blood cells have a cell wall, which does not protect them from bursting

After two hours, the color of the liquid in the beaker did not change. This shows that

glucose moved from the artificial cell into the beaker

starch did not pass out of the artificial cell

starch was digested to glucose in the artificial cell

glucose molecules combined to produce starch in the artificial cell

Identify the color of the contents of the artificial cell after two hours.

Amber brown

Blue/black

Clear

White

A model cell setup is represented in the "Initial State" diagram below. Which diagram indicates the area where each of these substances would be located after 20 minutes?

This laboratory setup would most likely be used to demonstrate

carbohydrate synthesis

active transport

diffusion

dehydration

What is one relationship between temperature and the rate of bubbles released in yeast, that is supported by the table?

The higher the temperature, the less bubbles released.

There is no relationship between temperature and number of bubbles released.

The lower the temperature, the less bubbles released.

The lower the temperature, the more bubbles released.

A student wants to bake the biggest loaf of bread in the local baking contest. Each contestant must use the same amounts of flour, sugar, and yeast, but is allowed to vary the type of sugar. Yeast is a microorganism that carries out cellular respiration, which produces carbon dioxide, making the bread rise. The student designs an experiment using the setup below to determine which sugar source (glucose, sucrose, or fructose) will cause the yeast to produce the most carbon dioxide and therefore,the biggest loaf of bread. What is a possible hypothesis for this experiment?

If glucose is the sugar that is used, it will produce the most carbon dioxide.

Which sugar will produce the most carbon dioxide?

Glucose and fructose both produced a balloon circumference of 10 cm.

The dependent variable is the amount of carbon dioxide produced.

What group is missing from this experimental setup?

An experimental group with double the amount of glucose.

An experimental group with glucose, sucrose, and fructose.

A control group with glucose, sucrose, and fructose.

A control group with just water and yeast solution.

Part of a laboratory procedure is shown in the diagram below. This setup would most likely be involved in a procedure to

stain specimens while making a wet mount

test for the presence of glucose using an indicator

separate pigments in a mixture

determine the pH of solution

Which substance is a suitable indicator for detecting the presence of starch in a plant cell?

Fehling's solution

pH paper

bromthymol blue

iodine solution

14.

Some organs in the human body, such as the kidney, help to carry out the function of excretion. Where do these organs get the cellular energy that is directly necessary to carry out these functions?

water that is eliminated by the organs

ATP that is produced in the mitochondria during cellular respiration

glucose that is produced in the chloroplasts during photosynthesis

blood flowing through the organs

15.

During the process of cellular respiration, energy is released from

carbon dioxide

oxygen atoms

water molecules

chemical bonds

16.

Which of the following is unable to diffuse through the cell membrane?

Water, because it is too small

Glucose, because it is too big

Starch, because it is too big

Oxygen, because it is too small

17.

How can we best describe the nature of science, and the discoveries made by different scientists throughout history?

Science remains static, unaffected by new discoveries.

Science adapts slowly to new information.

Science is a dynamic process, constantly evolving as new discoveries are made.

Science only changes when a groundbreaking discovery is made.

18.

In an appropriately designed experiment, a scientist is able to test the effect of

a single variable

multiple variables

the hypothesis

scientific observations

19.

Which process is represented by the diagram below?

diffusion

passive transport

active transport

cellular respiration

20.

How are single celled organisms able to carry out the same complex processes as multicellular organisms?

They are not, because single celled organisms are not actually living.

Single celled organisms contain structures called organelles that carry out functions similar to organs in multicellular organisms.

Single celled organisms contain structures called organs that carry out functions similar to organelles in multicellular organisms.

Single celled organisms are as complex as multicellular organisms

21.

What are the building blocks of this molecule?

Amino Acids

Nucleic Acids

Simple Sugars

Fatty Acids

22.

How does the body respond when more oxygen is required?

Decreasing heart rate

Increasing heart rate

Decreasing blood pressure

Increasing blood pressure

23.

According to the model, what would happen if the pancreas did NOT detect rising blood glucose (sugar) level?

Glucagon would be released in order to maintain homeostasis

Blood sugar would still decrease because pancreas function is not necessary

Blood sugar would stay above normal, resulting in an imbalance in homeostasis

Blood sugar would stay above normal, resulting in maintenance of homeostasis

24.

Which organelle does aerobic cellular respiration happen in?

Nucleus

Mitochondria

Chlorophyll

Chloroplast
