The correct answer is B
In he process called the central dogma of molecular biology information about the protein production is translated from the DNA molecule to a functional protein.
In the first step, the mRNA is transcribed from a gene on the DNA. The mRNA conians the information about the sequence of amino-acids that will build the protein.
In the ribosomes, amino acids are bound together bu the halp of ribosomal and transport RNA. After additional changes a protein is formed.
Answer:
b
Explanation:
chitin helps build natural structures like exoskeletons and cell walls
Inside a water molecule, hydrogen and oxygen are connected by polar covalent bonds. This results from oxygen's higher electronegativity, causing the shared electrons to spend more time near the oxygen atom, creating a polarity. Hydrogen bonds, although not found within single water molecules, exist between different water molecules and contribute to water's overall properties.
The bonds found inside a water molecule between hydrogen and oxygen are polar covalent bonds. A covalent bond is established when electrons are shared between atoms. In a water molecule (H2O), electrons are shared between hydrogen and oxygen. However, oxygen has a greater electronegativity than hydrogen, causing the shared electrons to spend more time closer to the oxygen atom, hence creating a polarity.
Sometimes, a weaker bond known as a hydrogen bond, which is a type of dipole-dipole interaction, can be found between water molecules. Although these are not found inside a single water molecule, they are crucial for the properties of water as a whole.

A molecule is a fundamental concept in chemistry that represents the smallest unit of a chemical compound that retains the properties of that compound. It's formed when two or more atoms come together and bond with each other.
Atoms are the basic building blocks of matter. They consist of a nucleus composed of protons and neutrons, surrounded by a cloud of electrons. Atoms can combine with each other through chemical bonds to form molecules. One of the most common types of chemical bonds is the covalent bond. In a covalent bond, atoms share electrons to achieve a more stable electron configuration.
In ionic bonding, atoms transfer electrons to each other, resulting in the formation of ions with opposite charges. These ions are attracted to each other, creating an ionic bond. The arrangement of atoms within a molecule is crucial to its properties and behavior. The type and arrangement of bonds determine the molecule's shape and how it interacts with other molecules.

Explanation:A special case of polar forces occurs in what is called the hydrogen bond. In many situations, when hydrogen forms a covalent bond with another atom , electrons move toward that atom, and the hydrogen acquires a slight positive charge. The hydrogen, in turn, attracts another atom, thereby forming a kind of bridge between the two.

3)compound
4)element
ELEMENT
A pure substance is one that is composed of only one type of material.
This material may not necessarily be made from only one type of element, but can be composed from different elements yet be pure. An example of this is water. Water is made up of oxygen and hydrogen. Water that is free of contamination is termed as pure.
Examples of pure substances are:
1.Gold
2. Iron
3. Carbon
4. Sugar
5. Nitrogen gas
6. Oxygen gas
7. Salt
