<u>Answer:</u> The mass number of an element tells us about the number of particles present in the nucleus of an atom
<u>Explanation:</u>
Nucleons are defined as the sub-atomic particles which are present in the nucleus of an atom. Nucleons are protons and neutrons.
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
<u>For Example:</u> Taking an isotope of chlorine, Cl-35
Atomic number = Number of protons = 17
Mass number = Nucleons = 35
Hence, the mass number of an element tells us about the number of particles present in the nucleus of an atom
Answer:
The correct answer is - transitional fossil between fish and amphibian.
Explanation:
Transitional fossils is a fossil that remnant of an organism or life form that shows the characters of an ancestral species and current descendant of species. These fossils are use as the evidence and study of evolution of the descendant from the ancestral group.
In this case discovered fossil had scales, gills, fin, and neck bones which helps in the proping itself out of the water. These characteristics are common in the fish and amphibian that suggested that it is a transitional fossil between fish and amphibian.
Thus, the correct answer is - transitional fossil between fish and amphibian.
The majority of signal molecules are peptides and small proteins. Both are made of a chain of amino acids, the difference being the number of amino acids that make up the molecule. Generally, if the signal molecules has fewer than 50 amino acids it is considered a peptide. If it has more it is considered a protein.
The answer to the question is Carbon dioxide
