• It can reflect light

• It can refract light

• It can increase the intensity of light

• It can increase the wavelength of light

How can the behavior of light be described as it leaves the vacuum of space and enters the Earth’s atmosphere?

• Light waves slow down as they enter the Earth’s atmosphere from space.

• Light waves continue at the same speed as they enter the Earth’s atmosphere from space.

• Light waves speed up and then slow down as they enter the Earth’s atmosphere from space.

• Light waves slow down and then speed back up as they enter the Earth’s atmosphere from space.

Which of the following best explains why both plants and animals cells have mitochondria?

• The sugar is created in the mitochondria by both animal and plant cells.

• The sugar found in the food they both eat is broken down by the mitochondria in animal and plant cells.

• The sugar formed from photosynthesis is broken down by the mitochondria in the animal cell, and the sugar plants get from the food they eat is broken down by the mitochondria in the cell.

• The sugar formed from photosynthesis is broken down by the mitochondria in the plant cell, and the sugar animals get from the food they eat is broken by the mitochondria in the animal cell.

Which statement below best describes a cell structure found in plants and NOT in animal cells?

• This cell structure supplies energy to the cell.

• This cell structure pads and supports organelle inside the cell.

• This cell structure allows for materials to move in and out of the cell.

• This cell structure is made of cellulose to protect and support the cell.

Jorge made a mistake when creating the table and needs to correct the function of one organelle.

• cell wall

• vacuole
