SC.8. N.1.1
As part of an investigation, one set of 10 bean seedlings were grown in the dark, while another set of 10 seedlings were grown in the sunlight. All other growth conditions were kept the same in both setups. The seedlings grown in the dark were white with long, slender stems. These seedlings eventually died. The seedlings grown in the sunlight were green and healthy. Which hypothesis was most likely being teste in this investigation?
A. Plants grown in the dark cannot perform the process of respiration.
B. Sunlight is necessary for the normal growth of bean plants.
C. Light is necessary for the germination of bean seeds.
D. Light is necessary for proper mineral absorption by plants.
SC.8. N.1.1
An experiment was carried out to determine whether drinking sodas with sugar increase the pulse rate. The pulse rate of two groups of people at rest were measured. Group A was sodas with sugar and group B was given sugar-free soda. One hour after drinking the soda, the pulse rates were measured. The participants in the experiment were all the same age, and they were given the same amount of soda.
What is the outcome variable (dependent) in this experiment?
A. a. type of soda given to each group
B. amount of soda given to each group
C. pulse rate of each group.
D. age of participants of each group

A. experimental group
B. limiting factor
C. control
D. indicator

C. Tropical plants grew in the South Pole during the summer.
D. The ocean currents carried the fossilized remains

A. The object will sink because it is less dense than isopropyl alcohol.
B. The object will float because it is less dense than isopropyl alcohol.
C. The object will sink because it is more dense than isopropyl alcohol.
D. The object will float because it is more dense than isopropyl alcohol.

A. Some of the heat from the lemonade transferred to the ice cubes and causes them to melt.
B. The temperature of the ice cubes remains the same as the temperature of the lemonade drops.
C. The cold from the ice cubes is transferred to the lemonade causes the ice cubes to warm up and melt.
D. Heat is transferred between ice cubes and the lemonade, which causes the temperature of the lemonade to increase.
