Answer:
Carbon-14 is an isotope of carbon and differs in the number of neutrons in their nucleus.
Explanation:
all isotopes have the same number of protons and electrons, but differ in the number of neutrons. They have identical chemical behaviour but with different atomic masses and physical properties
Butane: It is an organic compound belongs to class of alkane having molecular formula .
Butane consist of four carbon and ten hydrogen atoms attached by single covalent bond. Carbon and hydrogen atoms are attached in such a way that the valency of carbon that is four and valency of hydrogen that is one is completely satisfied and thus, results in the formation of stable compound.
The structure of butane with hydrogen atoms is shown in the image.
In a food chain we arrange the energy in the form of a pyramid.
The producers are on the base of pyramid and then consumers are towards peak.
in the given food chain grass is being eaten by grasshopper which are food of birds.
Grasshoppers are also eaten up by Hawks. so both brids and hawks are feeding upon grasshoppers thus the amount of energy transferred from the grass to the grasshopper is the same as the amount of energy transferred from the grasshopper to the bird.
The answer sould be Component of Thyroxine, Thyroxine contains iodine and are formed from thyronines, which are composed of two molecules of the amino acid tyrosine. Thyroxine contains four iodine atoms, and triiodothyronine contains three iodine atoms.
Each scientist could be working on the problem for different reason. Or, each scientist could be focused on different elements of the problem, concluding in different conclusions between the scientist.
