Plant stems are often stiff. They provide support for the plant. They hold the leaves up so that they can get sunlight. What is another role of the plant stem?
getting rid of waste as oxygen gas
making sugars for the plant to use as food

Some stars in the picture look bigger and brighter than others. What reasoning explains why a star might look bigger or brighter than another star?
The star is hotter.
The star is closer to Earth.
The star has more planets around it.
The star is closer to the center of the group.
During the daytime, a desert can be very hot. At night, the temperature is much cooler. What reasoning explains what causes the difference in day and night temperatures in a desert?
The sun gives off more heat energy during the day than it does during the night.
Winds that blow only at night take any heat energy that the desert stored during the daytime.
Any heat energy absorbed by the desert sand during the day is stored by the desert sand at night.
During the day, the sun heats the desert, and that heat is lost during the night after the sun has set.

Light travels in straight lines and does not bend around the moon.
Light travels in curves that bend to hit only one side of the moon.
When your hands feel cold, rubbing them together very quickly can make the skin feel warm briefly. What reasoning explains why rubbing your hands together makes them warm?

Movement causes potential energy to produce heat.
Rubbing hands together can cause a fire that produces heat.
Activity causes the heart rate to speed up and warm the blood.
What process is shown in the picture?
breathing
evaporation
photosynthesis

The sun is a star that is at the center of our solar system. Like other stars, it is a bright ball of hot gases. During the day, the sun appears much larger in the sky than other stars do at night. Which reasoning tells why the sun looks so much bigger than other stars?

Stars become larger during the day than they do at night.
The gases in the sun burn hotter than those of other stars.
Stars give off more light during the day than they do at night.
Jenny wants to test whether plants grow in the direction of a light source. She sets up two covered boxes, each with a plant in it. She cuts a hole in the right side of the first box and places a lamp so the light shines through the hole. She cuts a hole in the center top of the second box and places a lamp so the light shines through the hole. She waters each plant daily and checks their growth after 4 weeks. What results would provide evidence that plants grow in the direction of a light source?
Both plants are exactly the same.
The plant in the first box grows to the right, while the plant in the second box grows straight up.
The plant in the first box does not grow at all, while the plant in the second box grows normally.
The plant in the first box grows normally, while the plant in the second box does not grow at all.
