Answer : The correct option is, (B) Germanium

Explanation :

As we know that the material are divided into three categories which are conductors, insulators and semiconductors.

Conductors : It is a type of substance which conduct electricity that means it allow the electrons to flow through them.

Example of conductors are, iron, aluminium, gold, etc.

Insulators : It is a type of substance which does not conduct electricity that means it does not allow the electrons to flow through them.

Examples of insulators are, glass, rubber, ceramics, etc.

Semiconductors : It is a type of substance which conduct electricity under certain conditions that means it allow the electrons to flow through them. The conductivity level of semiconductors lie between the conductors and the insulators.

The good examples of semiconductors are silicon, germanium, gallium, and selenium.

In the given options, aluminium, gold are the metals which conduct electricity and concrete is an insulator which do not conduct electricity while the germanium is the good semiconductor.

Hence, the correct option is, (B) Germanium

Once a protein is made, its biochemical and structural properties play a role in producing ________.

nasty-shy [4]

Answer:

(D) mutant

Explanation:

Translation occurs at the ribosome, which consists of rRNA and proteins. ... Then, rRNA helps bonds form between the amino acids, producing a polypeptide chain. After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein. Learn how their functions are based on their three-dimensional structures, which ... bonds are formed by a biochemical reaction that extracts a water molecule as it joins to protein structure because these side chains can bond with one another to these stable folding patterns make up the secondary structure of a protein. A genotype is an organism’s set of heritable genes that can be passed down from parents to offspring. The genes take part in determining the characteristics that are observable in an organism, such as hair color, height, etc. An example of a characteristic determined by a genotype is the petal color in a pea plant. Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.

All of the following are major functions of proteins except 1.control of biochemical reactions. 2.support for organs or tissues.

Galina-37 [17]

Answer:

<h2>5.storage of energy</h2>

Explanation:

Proteins are important biomolecules that are a type of macromolecule.
This macromolecule is made up of a monomer that is called amino acid.
There are many functions of the protein molecules in living organisms.
They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
They also play an important role in the immune system.
The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.
