The correct answer is D. House cats, lions, and tigers belong to the same class and family.
Explanation:
Taxonomy classifies animals using different levels such as kingdom, family, order, species, etc. that show the features of the organism and its relationship or similarities with others. In the chart presented, the only level that is different for the three animals is the last one, which is the species level because in this the cat is classified as Domesticus, the lion as Leo, and the tiger as Tigris. This implies the other levels including the class (Mammalia or mammal) or family (Felidae) is the name of the three animals. This makes the last answer correct and shows these three animals are closely related.

Explanation:
As each half hour passes, the colony of bacteria doubles. Initially, the numbers are fairly low, but the amounts become larger and larger as they compound.
Hour 0- 1
Hour 0.5- 2
Hour 1- 4
Hour 1.5- 8
Hour 2- 16
Hour 2.5- 32
By hour 10, the bacteria will have increased to 1048576. By hour 15, the number of bacteria will be 1073741824. By hour 24, the colony will contain 281474976710656 bacteria.
