    Name the oxygen-transporting protein found in red blood cells.  - ProProfs

    Name the oxygen-transporting protein found in red blood cells. 

    • Wbc

    • Dna

    • Gene

    • Hemoglobin

    Correct Answer
    A. Hemoglobin
    Explanation
    Hemoglobin is the correct answer because it is the oxygen-transporting protein found in red blood cells. It binds to oxygen in the lungs and carries it to the body's tissues, ensuring that oxygen is delivered to where it is needed. Hemoglobin also helps in the transport of carbon dioxide, a waste product, from the tissues back to the lungs for exhalation. This protein is essential for the proper functioning of the respiratory system and plays a crucial role in maintaining the body's oxygen balance.

    Which is a biological macromolecule? - ProProfs

    Which is a biological macromolecule?

    • Amino acid

    • Salt

    • Sand

    • Ion

    Correct Answer
    A. Amino acid
    Explanation
    An amino acid is a biological macromolecule because it is a building block of proteins, which are essential macromolecules in living organisms. Proteins perform a wide range of functions in the body, including structural support, enzymatic activity, and cell signaling. Amino acids are linked together through peptide bonds to form polypeptide chains, which then fold into functional proteins. In contrast, salt, sand, and ion are not biological macromolecules but rather inorganic substances or particles.

    Which is a biological macromolecule? - ProProfs

    Which is a biological macromolecule?

    • Organic

    • Acid

    • Nucleic acid

    • Base

    Correct Answer
    A. Nucleic acid
    Explanation
    Nucleic acid is a biological macromolecule. It is composed of nucleotides and plays a crucial role in storing and transmitting genetic information. Nucleic acids include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), which are essential for the functioning and development of all living organisms.

    Alterations in structures affect _________________.  - ProProfs

    Alterations in structures affect _________________. 

    • Form

    • Life

    • Functions

    • Works

    Correct Answer
    A. Functions
    Explanation
    Alterations in structures can have a direct impact on the functions of a system or organism. When the structure of something changes, it can lead to changes in how that thing operates or performs its intended tasks. For example, if the structure of a protein is altered, it may no longer be able to carry out its specific function in the body. Therefore, alterations in structures can affect the functions of the system or organism.

    An analytical technique that sorts ions based on their mass to charge ratio is called ___________________.  - ProProfs

    An analytical technique that sorts ions based on their mass to charge ratio is called ___________________. 

    • Abstract

    • Ionization

    • Mass spectrometry

    • Chagrin

    Correct Answer
    A. Mass spectrometry
    Explanation
    Mass spectrometry is an analytical technique that sorts ions based on their mass to charge ratio. It involves the ionization of molecules, followed by the separation and detection of the resulting ions. By measuring the mass to charge ratio of ions, mass spectrometry can provide valuable information about the composition, structure, and abundance of molecules in a sample.

    Structural biology is concerned with the molecular structure of ______________.  - ProProfs

    Structural biology is concerned with the molecular structure of ______________. 

    • Life

    • Macromolecules

    • Physics

    • Biology

    Correct Answer
    A. Macromolecules
    Explanation
    Structural biology is a field that focuses on studying the molecular structure of macromolecules. Macromolecules are large and complex molecules that are essential for various biological processes. By understanding their structure, scientists can gain insights into their functions and mechanisms, which can be crucial for developing new drugs and therapies. Therefore, macromolecules are the main subject of study in structural biology.

    A structure could also be termed as ________________.  - ProProfs

    A structure could also be termed as ________________. 

    • Erect

    • Organization

    • Construction

    • Heading

    Correct Answer
    A. Organization
    Explanation
    A structure could also be termed as an organization because both terms refer to a system or arrangement that is designed to achieve specific goals or objectives. Just like an organization, a structure has various components or elements that work together in a coordinated manner to fulfill its purpose. Additionally, both terms imply a sense of order, hierarchy, and purposeful design. Therefore, it is appropriate to describe a structure as an organization.

    A structure is an arrangement of _________________. 

    • Ions

    • Places

    • Structures

    • Parts

    Correct Answer
    A. Parts
    Explanation
    A structure is an arrangement of parts.

    Which is a method of determining the structure of biomolecules? - ProProfs

    Which is a method of determining the structure of biomolecules?

    • Enlargement

    • Staining

    • Proteolysis

    • Writing

    Correct Answer
    A. Proteolysis
    Explanation
    Proteolysis is a method of determining the structure of biomolecules. It involves the enzymatic breakdown of proteins into smaller fragments, allowing for the identification and characterization of their amino acid sequences. This technique is commonly used in protein research and structural biology to gain insights into the composition and organization of biomolecules.
