Amoebas can adjust their metabolic rate to survive in different temperatures. In extreme heat, they may form protective cysts to prevent dehydration, while in cold temperatures, they may become dormant until conditions become more favorable. Rapid temperature changes can stress amoebas and affect their motility and feeding behavior.
When a cold pack is broken, it initiates a chemical reaction between the substances inside the pack. This reaction absorbs heat from the surrounding environment, causing the pack to feel cold. Breaking the pack allows for the substances to mix and react, resulting in the release of cold temperatures.
Nerves carry messages to the muscles to react. Nerves help us feel pain, heat, and cold.
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
Amoebas respond to stimuli through a process called chemotaxis, where they move towards or away from chemical signals in their environment. When an amoeba encounters a food source, it extends pseudopods towards it, engulfs the food through phagocytosis, and then digests it internally. Additionally, amoebas can sense changes in temperature, light intensity, and pH levels in their surroundings to navigate and survive.
Cold is the absence of heat. No doubt about it . . . take away enough heat, and you can make anything cold.
Cobalt does not react with cold water. With extreme heat, CoO can form.
Cold causes matter to contract. Heat causes matter to expand.
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.

Breaking the pack allows for the substances to mix and react, resulting in the release of cold temperatures.
Metals like copper, silver, and gold do not react with cold water because they are less reactive. This is due to their position in the reactivity series, where they do not displace hydrogen from water.
alkali metals react violently in cold water
Nerves carry messages to the muscles to react. Nerves help us feel pain, heat, and cold.
Zinc reacts with steam to form zinc oxide and hydrogen gas because steam provides the necessary heat to initiate the reaction. Cold water does not provide enough energy to break the bonds in the zinc and water molecules for the reaction to occur.
Mg does not react with cold water while Ca, Sr, and Ba react with cold water to form metal hydroxide and hydrogen gas.
Amoebas are classified as protists.
