An atom of hydrogen and an atom of carbon are known as hydrocarbons Or hydrogen atom bonded to carbon backbone.
Hydrocarbons are defined as an atom of hydrogen and an atom of carbon are known as hydrocarbons Or hydrogen atom bonded to carbon backbone. Carbon has been known as the element which has a chemical by nature and it has been represented by C and the atomic number of carbon has been 6. The atomic mass of carbon would be 12.011 u and the carbon contain 2, 4 electrons per shell with its electronegativity of 2.55 .
The main function of the carbon compounds has to maintain earth's atmosphere and temperature and to supply energy that must works as the fuel for our economy.The atomic structure of the carbon has been designed in such a manner that it must contain 6 number of electron, 6 number of protons, and 6 number of neutrons.
Therefore, An atom of hydrogen and an atom of carbon are known as hydrocarbons Or hydrogen atom bonded to carbon backbone.

Answer:
C. pteriodophyte
Explanation:
The imagen shows the life cycle of a pteriodophyte, also known as fern. In the enves of the leaves there are structures called sporangia. They release the spores. the spores germinate and become a gametophyte. Then the anterozoids fertilize the ovocellula and form a protalo with embryo or sporophyte.
Answer: not B
Explanation:
experiment with phosphorus and nitrogen being added to the soil of a
growing plant. When the amount of added nitrogen is increased, the
growth is not affected. When the amount of added phosphorus is
increased, the growth speeds up. Which of these two nutrients is the
limiting nutrient in this situation?
Answer
A.phosphorus
B.nitrogen
C.There is no limiting nutrient in this situation.
D.More information is needed.
Minerals have the property of cleavage to split into different parts, particular colors to particular minerals, and magnetism due to presence of electrons. Thus, the correct option is D.
Minerals are the elements which are found in the Earth crust and in foods that our body need to undergo development and function. Some of the essential minerals for health of a living organism include calcium, phosphorus, potassium, sodium, chloride, copper, iodine, etc.
Minerals show the property of cleavage, through this large pieces of minerals breaks into smaller ones which can be further used in different processes.
Different minerals have different colors which can be changed due to environmental conditions and reactions.
Minerals show magnetism. It is property responsible for the magnetic behavior of minerals due to presence of electrons in the valence shells.
Therefore, the correct option is D.
