Answer:
Explanation:
These are the two basic forms of energy. The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
Energy from the sun reaches Earth by way of radiation.
The sun cannot conduct heat to the Earth directly because the two bodies are not in contact with each other. Convection is also impossible, as no medium connects the two bodies to facilitate heat flow. Instead, the sun radiates much of its energy as light of various wavelengths. Some of this radiated light is in the infrared part of the spectrum and reaches Earth as heat.
Light in the visible part of the spectrum also has the effect of warming the Earth. It does this by penetrating the atmosphere and being absorbed by the land and water. Once the Earth has absorbed all of the energy it can hold, it begins to radiate energy back toward space. This terrestrial radiation is primarily in the infrared band of the spectrum, which is absorbed by aerosols in the atmosphere. These greenhouse gases trap heat and store up the surplus energy of the Earth's allotment of solar radiation. Eventually, even the atmosphere reaches thermal saturation and radiates waste energy back out into space.

Answer:
The given statement is false.
A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.
The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).
The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.
Construction of roads inside a forest has resulted in fragmentation of natural habitat.
<h3>What is Fragmentation?</h3>
This is the process of breaking down larger particles into smaller bits known as fragments.
When it happens to a large population of organisms there is a decreased the chance that an individual would find an unrelated mate.

Answer:
78%
Explanation:
Air is a mixture of nitrogen 78%, oxygen 21%, argon 0.9%, carbon dioxide 0.04% and other gases. Nitrogen is an element that makes up 78% of the air. It is essential to plants for protein synthesis. Though present in large quantities as free nitrogen gas in the atmosphere, it is taken up by plant roots only in the form of ions, such as nitrates and nitrites. Nitrogen is continually recycled in the ecosystem through biological processes involving bacteria.
