What does the chemical elemental basis of life say? A question of the dialectics of nature

Man was born of heaven and earth, nature created man, man knew nature, man learned the knowledge given by nature, man used this knowledge to transform nature.

Basic elements: c, h, o, n, s, p

The main elements are the front four.

A large number of elements are: C, H, O, N, S, P, FE, CA, NA, K, MG, I will not change the above answer.

The main elements are carbon, hydrogen, oxygen and nitrogen, because sugars and proteins are composed of these elements, while sugars provide energy, and proteins make up carriers, tissues, and ......

Basic elements: hydrocarbons, hydrogen, oxygen, nitrogen, sulfur, phosphorus, phosphorus is the element that makes up DNA (genetic material).

Macroelements: hydrocarbon, oxygen, nitrogen, sulfur, phosphorus, iron, calcium, sodium, potassium, magnesium. These are abundant in individuals, so they are called macroelements.

There are no boundaries between these definitions, and you can see that the first few are the same, but I don't know why the biology books are so tangled. The question asks you about the basic elements, and you answer that it is enough for hydrocarbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. - You said you were in junior high school, so I don't have to answer such complicated ......Sorry to confuse you. ）

The basic elements of life - security, diversity, value presence, relationship, extension, sharing.

Carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, zinc, iron, bismuth, copper, molybdenum, calcium, sodium, potassium, magnesium.

This statement is absolutely true. This is because living organisms are composed of organic and inorganic matter, and the chemical elements that make up organic matter ultimately come from inorganic nature.

All the nutrients that organisms need for growth and development ultimately come from inorganic nature.

Life itself evolved from inorganic nature. Inorganic, organic, lower organisms, higher organisms.

All the chemical elements that living organisms possess are found in nature; There are chemical elements that nature has, but living organisms do not necessarily have.

Yes. The biological and inorganic worlds are united. Elements in any living organism can be found in the inorganic kingdom.

1. Under natural conditions, more or less more than 90 kinds of elements can be found on the earth, according to the grasp of the situation, most scientists have a more unanimous opinion, that there are 29 kinds of essential elements for life, including hydrogen, boron, carbon, nitrogen, oxygen, fluorine, sodium, magnesium, silicon, phosphorus, sulfur, chlorine, potassium, calcium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, selenium, bromine, ranium, molybdenum, tin and iodine.

2. Among the 29 essential elements for life, they can be divided into macro elements (macro elements) and trace elements according to the content in the body.

What is called the element of life is ().

Correct answer: Nitrogen; n

Answer]: C Knowledge Points] This question tests the knowledge of the elements and compounds that make up the cell.

Answer] c. Analysis] The monomer of polysaccharides is monosaccharide, the monomer of protein is reed amino acid, and the monomer of nucleic acid is nucleotide (4 kinds of deoxyphore calendar nucleotides and 4 kinds of nucleoides or sugar nucleotides), so a and d are correct; The proportion of carbon and hydrogen content in fats is higher than that in sugars, and more oxygen is required for complete oxidative decomposition, so b is correct; Carbon is the living element of living organisms, and inorganic compounds do not necessarily contain carbon, such as water does not contain carbon elements, so c is false.

Life comes from non-living matter, which is explained by () Shou Brother Suixian.

a.Reddy. b.Miller.

c.Obacha Teasewood.

d.Pasteur envied the revival.

Correct answer: c
