Reading the passage, answer the questions below : (28-30)
Three major types of nutrients – carbohydrates, proteins and fats – make up most of the food you eat.

The different versions of a gene are called alleles. When two different alleles occur together, one is
often expressed while the other has no obvious effect on the organism’s appearance. The expressed
form of the trait is dominant. The trait that was not expressed when the dominant form of the trait was
present is called recessive. Imagine a plant that has both purple and white alleles for flower color. If the
plant blooms purple, then purple is the dominant form of the trait. Therefore, white is the recessive
form.

Read the passage below to answer questions 169-171.
A marine biologist scuba dives to study organisms in the ocean. During a dive on a coral reef, she found
an interesting organism. When she studied the organism with a hand lens, she found that it looked like
a bag pierced by numerous tiny openings. As she observed the organism, she discovered that water
entered it through tiny openings called pores. Water left the organism through a large opening called
an osculum. The central cavity was lined with cells with whiplike structures that beat back and forth.
These cells moved water through the organism and trapped food particles. The biologist also found that
she needed to handle the organism with care because it was covered with tiny spikes.
169. How does the organism rely on spikes?
A. They capture prey
B. They develop into new organisms
C. They support the body and provide protection
D. They digest food.
170. How does the organism obtain food?

209. A student wanted to test how temperature affects the sprouting of alfalfa seeds. She set up
five dishes and placed ten alfalfa seeds on a moist paper towel in each dish. Each of the five
dishes was kept at a different temperature – 10 degrees Celsius, 15 degrees Celsius, 20 degrees
Celsius, 25 degrees Celsius, and 30 degrees Celsius. Which of these is the independent or
manipulated, variable in this experiment?

217. A group of New Jersey science students were working in a garden as a part of a botany unit.
They were having difficulty keeping their plants alive. They formed a hypothesis that a nearby
fir tree sapling was causing the soil to become highly acidic, and that the acid soil was
preventing other plants from growing. The students tested their idea by growing similar plants
in a container with a fir tree sapling. At the end of 12 weeks, they discovered that the pH of the
soil was highly acidic. The fir sapling was thriving. However, all but one of the other plant
samples were either dead or dying. What conclusion could the students draw from the data
given?
A. The plant that survived caused the problem.
B. The cause is unknown, but acid soil is not responsible for the death of the other
plants.
C. Acid soil could be responsible, but further testing, using controls, needs to be done.
D. The plants themselves appear to be causing the problem, and not the pH or other
factors in the soil.
