When dissolved in water, hydrogen ions are released from acids and hydroxyl ions are released from bases Good luck!
Mutations can be both harmful and helpful. It is helpful because it could help breed or sustain more species for better production or consumption. It is harmful because it could cause genetic disruption to a living organism that may impair its functioning as a whole.
hope this helps
Answer:
Water and temperature
Explanation:
Water and temperature are the two most important factors that regulate the distribution of organisms in terrestrial habitats. Water is required for survival by living beings. The availability of water is limited in many habitats such as desert habitats. In such land habitats with water scarcity, the organisms adapted to withstand the limited water availability are found.
Likewise, temperature also affects the distribution of organisms in terrestrial habitats. The presence of temperature conditions below and above the tolerance range of the organisms restricts their geographical distribution. Temperature regulates the enzyme kinetics. Metabolic pathways are catalyzed by enzymes that function under optimal temperature conditions only. Water serves as a medium for metabolic reactions and also regulates body temperature.
True.
People began to settle Sumer around 4500BCE. The Sumerians were in control of the area by 3000BCE. Their culture was comprised of cities such as Eridu, Nippur, Lagash, Kish, Ur, and Uruk.
