Which property is shared by the cells of all living things?

• The cells are surrounded by a phospholipid bilayer and a cell wall made of cellulose

• The cells contain DNA composed of adenine, thymine, guanine, and cytosine.

• The cells have chromosomes that are located inside a membrane-bound nucleus.

• The cells rely on mitochondria to carry out aerobic cellular respiration.

A segment of DNA is shown in the diagram. Which of these identifies the part of the DNA segment labeled X?

• Hydrogen Bond

• Phosphate Group

• Nucleotide

• Deoxyribose

Snowshoe hares can be found living in the Rocky Mountains of New Mexico. During the summer months, when there is no snow on the ground, the snowshoe hare’s coat color is typically brown. During the winter months, when the mountains are covered in snow, the snowshoe hare’s coat is typically white. Which statement describes the genetic basis for the seasonal changes in coat color?

• The snow causes mutations in the genes that regulate coat color so that snowshoe hares are adapted to their environment during the winter months.

• The genes that control coat color are regulated by hormone signals that are altered by changes in environmental factors.

• Sunlight causes cancer cells to develop in the bodies of snowshoe hares, resulting in an apparent brown-colored coat as a result of hair loss

• The genes that control coat color in snowshoe hares are deleted from the genome during the summer months.
