Answer:
hemoglobin, hemoglobin carries oxygen in the blood and it is made up of four subunits, two each of the α and β types.
Explanation:
Protein can have varying structures namely primary, secondary, tertiary and quaternary. An example of protein with a quaternary structure is hemoglobin.
What are different structures of protein?The function of protein is completely dependent on its folding. Protein can be folded into many types.
The macromolecule protein can have the following structural classification:
Primary structure: It is a linear chain of amino acids.Secondary structure: The linear chain folds to form secondary structure.Tertiary structure: it involves further folding of protein chain.Quaternaty structure: it is the spatial arrangement of the folded protein.Hemoglobin is one of the proteins that exhibits quaternary structure.
Thus, hemoglobin is an example of a protein that has quaternary structure.

Additional vascular tissue produced as secondary growth in a root originates from which cells?.
Answer:
The vascular cambium produces new vascular tissue and is responsible for most of the radial expansion of stems and roots.
Explanation:
Does this answer your question???
Additional vascular tissue produced as secondary growth in a root originates from Vascular cambium cells.
What is secondary growth?
Secondary growth happens in the vascular cambium of those plants, that is a skinny layer of tissue containing actively dividing cells. The vascular cambium is a meristematic tissue that develops among the stem's number one xylem and number one phloem.
The Vascular Cambium and Secondary Growth. The vascular cambium and cork cambium are secondary meristems which can be fashioned in stems and roots after the tissues of the number one plant frame have differentiated. The vascular cambium is accountable for growing the diameter of stems and roots and for forming woody tissue.

Which statement BEST describes what happens during the S-phase of the cell cycle?
A.Protein synthesis needed for spindle formation and mitosis.
B.DNA replication where the amount of genetic material is doubled.
C.The cell partitions the two copies of genetic material into the two daughter cells.
D.Cell division occurs and two cells are left; thus the cell cycle begins again.
Answer:
B
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Proteins that use energy from ATP hydrolysis to change the locations and compositions of nucleosomes are called ATP-dependent___complexes.
Answer:
Chromatin-remodeling
Explanation:
In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling.
Chromatin-remodeling complexes use energy from ATP hydrolysis to alter the arrangement of nucleosomes, making the DNA more accessible to other proteins.
How does the carbon dioxide necessary for photosynthesis enter plants? a. through their roots b. through openings in the leaves called stomata c. the plants produce their own complete supply d. none of the above please select the best answer from the choices provided a b c d
The process by which plants make their own food is called photosynthesis. The raw materials of it are carbon dioxide coming from stomata, water and sunlight.
What is stomata?Stomata is the opening for gaseous exchange and transpiration, present in epidermis of leaf.
Stomata are provided by two guard cells, which shrink and swell in order to open or close the stomatal pore respectively.
The carbon dioxide necessary for photosynthesis enter plants through these openings called stomata.

How many oxygen molecules can one hemoglobin carry.
Answer:
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
Answer:
Oxygen binds reversibly to harem, so each hemoglobin molecule can carry up to four oxygen molecules. Hemoglobin is an allosteric protein; the binding of oxygen to one harem group increases the oxygen affinity within the remaining harem groups.
