Mutation is needed for evolution to occur to ensure that strong species will dwell within the environment. Though this has little effect on allele frequencies, mutations still ensure the biodiversity of species. The theory of natural selection in a way proves this.
Answer:
Since hot water has more kinetic energy, any particles that are suspended in it move at a faster rate than in cold water.
Explanation:
Answer:
yes, sexual reproduction leads to the selection of better individuals for a particular environment
Explanation:
Natural selection can be defined as a mechanism associated with the survival and reproduction of individuals better adapted to their environment. Sexual reproduction is able to increase genetic variation, which is the primary source on which natural selection works. In consequence, individuals that exhibit an evolutionary adaptive phenotypic variant will have more chance to survive and to reproduce than those individuals with other less adaptive traits, thereby leading to evolution of the population and tending to optimize phenotypic variants for particular environmental conditions.
The main property of water that helps sustain life on earth is that water has. a high specific heat. This causes water to gain heat very slowly.
Specific heat is the amount of heat required to raise the temperature of water by one degree Celsius. Specific heat of water is 4, 186 joules /gram Celsius, and it is higher than that of a metal and of any other common substance.
Due to this, water resists tendency to evaporate or to vaporize and therefore plays the crucial role of stabilizing temperatures on earth for terrestrial life and at the same time enabling aquatic organisms to maintain relatively constant internal temperatures.
