Calcium and phosphorus are both essential for the proper growth of
a. bones
b. hair
C. fingernails
d. all of the above
Answer:
The real answer is A.
Explanation:
Calcium and phosphorus are both essential for the proper growth of Bones. So, the correct option is (A).
What are Bones?A bone is defined as the hard organ that forms part of the skeleton in most vertebrate animals and protects various other organs of the body that produce red and white blood cells, store minerals, provide structure and support for and enable mobility.
These come in a wide variety of shapes and sizes and have complex internal and external structures and are strong and rigid as well as being light weight and perform many functions.
Their functions include supporting the body's structure, protecting vital organs and allowing the body to move, and providing an environment for the bone marrow, where the body manufactures blood cells, and they store minerals, especially they act as storage areas for calcium. The skeleton accounts for about 15% of the body weight.
Thus, Calcium and phosphorus are both essential for the proper growth of Bones. So, the correct option is (A).

Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons
Complete question:
Knowledge of the amino acid sequences is important for several reasons. What is NOT one of those reasons
Amino acid sequences determine the three-dimensional structures of proteins. Knowledge of the sequence of a protein can help to prevent mutations. The sequence of a protein reveals much about its evolutionary history. The sequence of a protein is necessary to determine its function.Answer:
Knowledge of the sequence of a protein can help to prevent mutations.
Explanation:
Amino acids connect to each other by peptidic bonds to form a linear polymer. The number of amino acids composing the chain and the order in which they are arranged determines the primary structure of the protein.
The secondary structure is the folding that the polypeptide chain adopts thanks to the formation of hydrogen bonds between the atoms that form the peptide bond.
Protein functions depend on their aminoacids sequences. The primary structure of the proteins determines the three-dimensional one. Proteins with different functions have different sequences. And among species, proteins with similar functions have similar structures.
By knowing the sequence of amino acids, we can predict the function of the protein and we can classify them into different families. Integrants of these groups have at least 25% of their sequences identical to each other.
Also, the knowledge of the sequence allows establishing evolutionary and genetic relationships between different species.
When a mutation occurs in the sequence -an alteration in the primary structure- the protein function is modified. BUT knowing the sequence of a protein CAN NOT help to prevent mutations.
2. How does temperature describe motion?
Answer:
As the temperature increases, the kinetic energy of the molecules of the liquid increases. The movement of the molecules gradually overcomes forces of attraction between the molecules, with the result that they have greater freedom to move, over greater volumes.

What is the difference in the function of the glycoprotein structures of an HIV
virion and the cilia of an animal cell? *
Answer:
The glycoprotein structures are used for attachment, and the cilia are used to move fluids surrounding the cell.
The primary difference in the function of the glycoprotein structures of HIV and the cilia of an animal cell is that the glycoproteins are involved in the attachment of viral particles to the cellular membrane while cilia involve in the locomotion and sensory functions.
What are Cilia?Cilia may be defined as small, slender, hair-like projections present on the surface of animal cells. Such types of structures are involved in mechanoreception.
Glycoproteins mediate the function of attachment of viral particles to the host's cell membrane. Through this function, glycoproteins play an essential role in the replication cycle of the virus.
Cilia play an important in the locomotion of cells by migrating the body fluids that surround the cells. This process by cilia can significantly result in the cells migrating through the water.
Therefore, it is well described above.

which of the following is not part of the cytoskeleton?
Centrioles are not part of the cytoskeleton. Therefore, option D is correct.
What is the cytoskeleton?The cytoskeleton acts as a scaffold to define the form of the cell and the overall arrangement of the cytoplasm, giving the cell a structural framework. The cytoskeleton not only performs this structural function, but it also controls how cells move.
Actin filaments (also known as microfilaments), microtubules, and intermediate filaments are three primary structural elements of a cytoskeleton. A cytoskeleton is present in every eukaryotic cell, including those found in plants, mammals, fungi, and protists. Even prokaryotes have cytoskeletal proteins, but they differ from eukaryotic cells in terms of their constituent parts.
Centrioles are not part of the cytoskeleton. Therefore, option D is correct.

A

Interphase lasts for 98% of a cell's life. Thus option A is correct.
What are interphase?Interphase are defined as the G1, S, and G2 phases of the cell cycle, which are the parts of the cycle during which no changes can be seen under a microscope.
It can also defined as when a cell duplicates its DNA to get ready for mitosis during the cell cycle.
G1 phase (cell growth), S phase (DNA synthesis), and G2 phase are the phases of interphase (cell growth). After interphase, the mitotic phase, which includes mitosis and cytokinesis and results in the formation of two daughter cells, starts.
It is important because it enables the cell to develop, replicate its DNA, and finalize preparations for cell division, or mitosis, interphase is crucial for cell division. The cell expands physically and performs its function in the organism during G1. The cell replicates its DNA while it is in the S phase.
Thus, interphase lasts for 98% of a cell's life. Thus option A is correct.
