Answer:
Passive transport
Explanation:
In Passive transport the energy is not essential in other for transportation to take place.it is in active transport where you see the need of energy for the process to take place.Passive transport involves the action of facilitated diffusion and osmosis.
Answer:
sulphuric acid and ammonium hydroxide
Explanation:
They are different types of batteries. there are zinc carbon batteries, alkaline batteries, lithium carbon batteries, lead-acid batteries.
lithium is used for high performance devices such as smartphones, digital cameras and even electric cars.A variety of substances are used in lithium batteries, but a common combination is a lithium cobalt oxide cathode and a carbon anode
lead-acid batteries: This is the chemistry used in a typical car battery. The electrodes are usually made of lead dioxide and metallic lead, while the electrolyte is a sulfuric acid solution.
zinc carbon batteries; The anode is zinc, the cathode is manganese dioxide, and the electrolyte is ammonium chloride or zinc chloride.
alkaline batteries;The cathode is composed of a manganese dioxide mixture, while the anode is a zinc powder. It gets its name from the potassium hydroxide electrolyte, which is an alkaline substance.
Heat can be transferred from one object to another in 3 different ways.
1) Conduction : This is the mode of transfer of heat through solid medium.
Example : A metal rod getting hot when hold over a flame.
2) Convection : This is the mode of transfer of heat through liquids
Example : Boiling of water.
3) Radiation : This type of heat transfer does not require any medium.
Example : When we stand close to a campfire, we feel warmer. Here the heat travels through air.
In the given problem, when a person gets into a car with hot black leather, his skin comes in contact with the hot object. Here the heat gets transferred through the skin which is a solid medium.
Therefore this is an example of conduction.
Soil retains water and nutrients.
Several rocks rest in a stream.
Clouds create shade that changes temperatures
Abiotic factors are non-living components in the environment, or rather components in the environment that are not derived from life.
Explanation:
Abiotic factors interact with biotic factors to create ecoystems. An example of biotic factors interacting with abiotic factors include plants utilizing sunlight for photosynthesis and a wild beast drinking water form a watering hole in the middle of the savanna.
