Unicellular organisms are able to move towards and away from heat just like animals can. So if the temperature is too severe then the organism can move away. However most unicellular organisms like to live in severe temperatures.

How do unicellular organisms meet their basic needs?

Unicellular organisms meet their basic needs by metabolism (eating, drinking, breathe, and excrete) , growth (how big do they grow), Reproduction, irritability (how do they react to heat and cold, how do they react to danger), adaptation (how do they compete for food and space to survive) and movement (how do they move).


What's the reaction of colbalt with cold water?

Cobalt does not react with cold water. With extreme heat, CoO can form.


Why do large organisms live in cold climates but small organisms can't?

Larger organisms are required to consume and give off lots energy to survive. But, smaller organisms do not consume and release as much energy than larger ones. This energy, when given off, is represented by heat. Therefore, larger organisms produce more heat than smaller organisms, and this extra heat is required in cold climates.


How is the absorption of heat is important to aqauatic organisms?

It is important for organisms that live in the deep ocean to absorb heat, since it is very cold in that region of the ocean. Without the heat, they would die. Some organisms absorb heat from ocean vents, which provide a large amount of heat.


How does matter react to cooling?

Cold causes matter to contract. Heat causes matter to expand.

Why does zinc react with steam and cold water?

Zinc does react with cold water - it just does so very slowly. Steam is water that is very hot and thus as with any chemical reaction, the heat gives the molecules more energy and so they react faster.


Why does zinc react with steam and not cold water?

Zinc does react with cold water - it just does so very slowly. Steam is water that is very hot and thus as with any chemical reaction, the heat gives the molecules more energy and so they react faster.


How can our body react with heat and cold?

Our bodies are perfectly normal with heat and cold at the same time. Heat increases the flow of blood while cold decreases the flow of blood, so when they are both together reacting at the same time, basically the flow of blood is going at a normal rate


How does the environment of cells differ for a unicellular and multicellular organism?

Unicellular and multicellular environments may vary. Multicellular organisms are able to do more functions, and unicellular is one-cell, so their functions are limited, although some unicellular ones such as thermophiles and photosynthetic bacteria can thrive in any environment with sun or heat. Multicellular ones like animals, can be found anywhere active, although different types exist in different places.
