What elements make the tissues of the animal body?
Organs are composed of tissues, which are in turn composed of cells. Plants have three tissue types: ground, dermal, and vascular. Animals have four: epithelial, connective, muscle, and bone….Terms | Back to Top.
| Adipose tissue | myosin |
|---|---|
| actin | Nervous tissue |
| axon | neurons |
| bone | Platelets |
| Cardiac muscle | sarcomere |
Does animal tissue contain carbon?
Animal soft tissue has an effective atomic number of about 7 and consists mainly of hydrogen, carbon, nitrogen and oxygen, which substances are bound chiefly as water and proteins.
What is the chemical composition of most animals?
IT is customary to express the results of an ultimate analysis as mass percentages, thus: oxygen, 65 per cent; carbon, 18–25 per cent; hydrogen, 10 per cent, and so on.
What are the major chemical elements found in living systems?
In all living systems we can always find 4 basic elements: carbon, oxygen, nitrogen and hydrogen. Carbon is the basic building unit contained in living matter. The percentage of carbon in the mass of living matter is 19.4 %. Oxygen and hydrogen are present in almost all organic compounds which create living organisms.
What elements do humans need to survive?
Scientists believe that about 25 of the known elements are essential to life. Just four of these – carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) – make up about 96% of the human body.
What are the 10 most important elements?
- Oxygen.
- Hydrogen.
- Helium.
- iron.
- sodium.
- titanium.
- nitrogen.
- chlorine.
What’s the most useful element?
Life demands a huge variety of molecules, with chains and rings and branches and cages—tricks that iron rarely attempts. And so we are left with carbon, the most versatile, most adaptable, most useful element of all. Carbon is the element of life.
What is the most unique element?

What is the most beautiful metal on earth?
vanadium
What is the least known element?
The rarest of rare elements (at least in the everything-below-uranium category), astatine has never been found in nature, and less than 28 grams of the highly radioactive stuff are thought to be found on earth at any point.
What are the 6 unknown elements?
When Mendeleev proposed his periodic table, he noted gaps in the table and predicted that then-unknown elements existed with properties appropriate to fill those gaps. He named them eka-boron, eka-aluminium, eka-silicon, and eka-manganese, with respective atomic masses of 44, 68, 72, and 100.
What is 91 on the periodic table?
Protactinium
What are the unknown elements?
Above hassium (108), only copernicium (112), nihonium and flerovium (114) have known chemical properties, and copernicium is the only one that has been conclusively categorised. The rest remain elements with unknown chemical properties, for now.
Is there a 119 element?
Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. It is the lightest element that has not yet been synthesized.
