Answer: Dinosaurs
Many forms of plants, invertebrates, and fishes evolved during the Mesozoic Era. Since the dinosaurs were the dominant animals on land then, the Mesozoic Era is called the Age of Reptiles. Dinosaurs, however, became extinct even before the end of the Era.
Plants absorb carbon dioxide from the air, combine it with water and light, and make carbohydrates, the process known as photosynthesis.
Answer:
Climatology
Explanation: Climatology is the study of climate and how it changes over time. This helps people have a better understanding of the atmospheric conditions which can cause weather patterns and temperature changes over time.
Answer: Receptor protein.
Explanation:
The receptor protein on the cell surface would enable a cell to respond to glucagon. The glucagon binds to the GPCR on the liver and muscle cells and is known as glucagon receptor.
This receptor then stimulates cells to release glucose into the blood stream. Another hormones involved during this process is glucagon like peptide 1.
It works by binding to another GPCR which is GLP-1 receptor found on the pancreatic cells.
