Answer:
The force that causes most of the movement is thermal convection, where heat from the Earth's interior causes currents of hot rising magna and cooler sinking magna to flow
Explanation:
Its classified under cell regulation
Answer:
C. lack the enzymes to reduce N2 and NO3- to NH4+
Explanation:
Nitrogen fixation is a process by which atmospheric nitrogen (N2) is converted into ammonia (NH3) so that can be used in metabolic pathways (e.g. biosynthesis of macromolecules). Nitrogen fixation is performed by Archea and bacteria such as Azotobacter (usually in symbiosis with Leguminosa plants).
Nitrogen assimilation is a process in which organic compounds are made from inorganic nitrogen.
One-third of all waste in landfills are waste products. They are of no use. The rest of them is methane and other waste. Time to time methane is removed, for using it for different purposes. In landfills, the waste is buried and fresh waste is added to it every day. By anaerobic process, the waste is broken down into methane and other products.
Answer:
Most of the training of animals is learned from <u>conditioned response</u>.
Explanation:
A conditioned response is a learned response to a previously neutral stimulus. This is achieved by pairing a neutral stimulus with an unconditioned stimulus, which doesn't require any conditioning to cause a reaction.
For example, the smell of food is an unconditioned stimulus that causes the feeling of hunger. This type of response to food is an unconditioned response. If we paired another stimulus, for example, the sound of a whistle, with the smell of food, this stimulus on its own would eventually start causing hunger. This makes the sound of the whistle the conditioned stimulus and feeling hungry after hearing the sound of the whistle the conditioned response.
Most of the animal training is based on this principle.
