In what way would life be different if the element carbon is absent?
Without carbon, life as we know it would cease to exist because it is the main element in organic compounds that make up living things. The presence or absence of carbon determines whether an organism is organic or inorganic.
Which of the following is a trace element required by most living organisms which of the following is a trace element required by most living organisms?
Iron is required in living forms in trace amounts, which if increased causes toxic effects. Deficiency of iron leads to anemia.
Which of the following is a trace element that is required by all forms of life?
3.9. Iodine. Iodine is a vital trace element required at all stages of life especially during formative years. It is important to sustain the daily functions of human body and deficiency or excess can have significant adverse effects on the body.
Which of the following is a trace element that is required by humans and most other living organisms?
The correct answer is (C) iodine. (C) iodine. Iodine is an essential element in the body. When the body has an inadequate amount of…
What would happen if there was no carbon?
The Short Answer: Carbon is in carbon dioxide, which is a greenhouse gas that works to trap heat close to Earth. If it weren’t for carbon dioxide, Earth’s ocean would be frozen solid.
Is life possible without carbon?
It would be impossible for life on earth to exist without carbon. Carbon is the main component of sugars, proteins, fats, DNA, muscle tissue, pretty much everything in your body. As the most stable thing for an atom to have is eight electrons, this means that each carbon can form four bonds with surrounding atoms.
Which of the following is not a trace element in living organisms?
Mg is not a trace element. An element is absorbed by the plants in a small amount is termed as a trace element which is important for the correct growth, development, and physiology of the plants. Chromium, cobalt, copper, iron, manganese, magnesium, molybdenum, selenium, zinc all are the instances of trace elements.
Is carbon a trace element?
The human body is mainly composed of Hydrogen, Oxygen, Carbon and Nitrogen. These may be called Trace Elements or Ultratrace Elements. …
Which is not a trace element?
Mg is not a trace element. Chromium, cobalt, copper, iron, manganese, magnesium, molybdenum, selenium, zinc all are the instances of trace elements.
What is a trace element required by most living things?
Exact needs vary among species, but commonly required plant trace elements include copper, boron, zinc, manganese, and molybdenum. Animals also require manganese, iodine, and cobalt.
What is the atomic mass of carbon and oxygen?
Carbon has an atomic mass of 12 and an atomic number of 6; these values for oxygen are 16 and 8 respectively, for hydrogen 1 and 1, for nitrogen 14 and 7, for sulfur 32 and 16, for phosphorus 31 and 15. In the figure, how many electrons does nitrogen have in its valence shell?
Which is the most common isotope of carbon?
Carbon-12 is the most common isotope of carbon, and has an atomic mass of 12 daltons. A mole of carbon in naturally occurring coal, however, weighs slightly more than 12 grams. Why? A) The atomic mass does not include the mass of electrons. B) Some carbon atoms in nature have an extra proton.
Which is the most abundant element in living matter?
A) Carbon, hydrogen, oxygen, and nitrogen are the most abundant elements of living matter. B) Some trace elements are very abundant on Earth. C) Virtually all organisms require the same elements in the same quantities. D) Iron is an example of an element needed by all organisms.
What are the symbols for the elements in biology?
Each element symbol is provided by atomic number, mass number, and electron distribution diagram. The first row consists of hydrogen and helium from left to right. The second row consists of lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon from left to right.
