Classifying things by observation can best be done by using a : Taxon
Taxon divided organisms into different groups based on their unique similarities, and these similarities can be recognized by observing parts and behavior of the organisms. For example, Organisms generally divided into two groups. Those who have a backbone (vertebrata, such as mammals and reptiles ) and those who don't have backbones (such as arthropoda)
This is the best way to classifying the organisms because the similarities between them do not exist in their backbones alone. This give more room/possibilities for the classification. For example, The organisms could also be classified by other similarities (such as how they obtain food, their body structure, how they reproduce, etc)
The correct answer is Taxon.
Taxon - a unit of classification; element taxonomy group classification level taxonomic rank used in the biological classification. The concept is used mainly in biological taxonomy, where the group of organisms taxon understand, united on the basis of generally accepted methods of classification, interconnected by a degree of kinship, and sufficiently isolated from other groups that it could assign certain taxonomic category ( taxonomic rank) - species, genus, family, and so on.
B) Each element in the periodic table has a different number of valence electrons.
C) Valence electrons may be lost or gained by an atom when bonding occurs with another atom
D) When atoms collide with other atoms, they bond automatically
Answer: Option (C) is the correct answer.
Explanation:
Electrons present in the outermost shell of an atom are known as valence electrons.
For example, atomic number of calcium is 20 and its electronic configuration is 2, 8, 8, 2. This means that there are 2 valence electrons in a calcium atom.
These valence electrons can be lost or gained by an atom according to the octet rule and ability to gain stability.
Hence, we can conclude that the statement valence electrons may be lost or gained by an atom when bonding occurs with another atom, is True for valence electrons.
Valence electrons may be lost or gained by an atom when bonding occurs with another atom. The correct option is C.
Valence electrons are the electrons in the outermost energy level, also known as the valence shell, of an atom. These electrons are involved in the bonding behavior of atoms, determining how they interact with other atoms to form chemical compounds.
When atoms come into contact and form chemical bonds, valence electrons can be shared, transferred, or rearranged between the atoms.
This process occurs to achieve a more stable electron configuration for each atom involved.
In some cases, atoms may lose valence electrons to become positively charged ions.
This occurs when an atom has fewer valence electrons than the stable, full outer electron shell configuration. These positively charged ions are called cations.
Thus, the correct option is C.

The element is found in nucleic acids but not in proteins are the Phosphorous.
Nucleic acids are polynucleotides, which are long chainlike polymers made up of essentially identical nucleotide building components. Each nucleotide is made up of a nitrogen-containing aromatic base that is linked to a pentose (five-carbon) sugar, which is then linked to a phosphate group.
Proteins are composed of hundreds or thousands of smaller units known as amino acids that are linked together in lengthy chains. A protein is made up of 20 different types of amino acids that can be mixed. The sequence of amino acids determines each protein's distinct three-dimensional structure and function.
Thus, Phosphorous is the element which is found in nucleic acid but not in proteins.
