Compare and contrast the two types of bonds

Biology
1 answer:
stepan [7]3 years ago
8 0

Answer:

An ionic bond is formed between a metal and a non-metal. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.

Explanation:

There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.

<h3>What is called Parenchyma?</h3>

The term "parenchyma" refers to the tissues that are employed for function in both plants and animals. Unlike "structural" tissues like wood in plants or bone in animals, this tissue is "functional," carrying out activities like photosynthesis in plants or information stored in the human brain.

A specific kind of ground tissue with thin cell walls and the capacity to expand and divide is referred to as parenchyma in plants. The majority of the cells in leaves, flowers, and fruits are parenchyma. In these formations, "structural" rather than "parenchymal" tissue makes up the hard, structural elements including bark, outer coatings, and major veins.

Theophrastus , Carl Linnaeus , Aristotle, charakan . Find the odd one
serious [3.7K]

Answer:

Charakan

Explanation:

The odd one out would be Charakan.

Theophrastus, Carl Linnaeus, and Aristotle are all <u>scientists that contributed to the science of classification of living organisms (taxonomy)</u>.

<em>Aristotle was the first scientist to classify living organisms into plant and animal kingdoms based on the artificial system of classification.</em>

<em>Theophrastus was a student of Aristotle and he wrote a book, De Historia Plantarum,  classifying about 480 plants.</em>

<em>Carl Linnaeus invented the binomial system of naming living organisms in which organisms are given two names - the species and the genus name. </em>

Charakan has no known contribution to taxonomy. Hence, the name is the only odd one.
