Answer:
d) The enzyme changes shape and can no longer speed up the reaction
Explanation:
Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.
Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
The reason that natural selection is important is that it's the central idea, stemming from Charles Darwin and Alfred Russel Wallace, that explains design in nature. It is the one process that is responsible for the evolution of adaptations of organisms to their environment.

Answer:
Forms of fossils and there arrangement with layer of rock.
Explanation:
- The seashore is a significant place for the depositional work of waves and it's also one of the significant places for the erosion and weathering of rocks.
- The presence of sedimentary rocks along the cliffs are essential for the discovery of fossils of plants and animals. Fossils of shells and other creatures that were of marine origin are mostly discovered near excavation sites. Fossil helps to prove the age of rocks and strata.
Alfred Russel Wallace, a biologist, naturalist and anthropologist who studied life in the tropics of Indonesia came up with the same idea of natural selection as Charles Darwin and prompted Darwin to publish his Origin of Specie sooner rather than later. He also studied the geographic distribution of species and as as well he was a social activist who criticized capitalism and warned of damage to the environment from man's economic activities.
