All cells have the same genetic information, but do not express the same genes. how is this possible? question 10 options: the differences are due to gene expression, which can be turned on and off. genetic material in a muscle cell is completely different from genetic material in a skin cell. genetic material is the same in all cells in the human body, except for reproductive cells. differences are due to major changes in genetic information from cell to cell.

Out of the seven main animal groups (fish, mammals, birds, insects, reptiles, amphibians, and arachnids), how many contain members with internal backbones? a. 5 b. 3 c. 7 d. 1

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
