Answer:
The difference in function and properties of polysaccharides such as starch, glycogen, celluose and chitin is due to the differences in their recurring monosaccharide units, the types of bonds linking these units and the degree of branching in the molecules.
Explanation:
Polysaccharides are large molecules of carbohydrates which are made up of recurring monosaccharide units. Examples of polysaccharides are starch, cellulose, glycogen and chitin. Each of these polysacccharides show differences in structure, properties and function. The difference in function and properties of polysaccharides such as starch, glycogen, celluose and chitin is due to the differences in their recurring monosaccharide units, the types of bonds linking these units and the degree of branching in the molecules.
Starch is the storage carbohydrate in plants and is composed of two types of glucose polymers, amylose and amylopectin. Amylose is composed of unbranched chains of D-glucose units linked to each other by (α1→4) glycosidic bonds. Amylopectin is a branched glucose polymer linked to each other by (α1→4) glycosidic bonds and (α1→6) at the branching points.
Glycogen is the storage polysaccharide in animals which is highly branched and compact. It is composed of (α1→4) linked glucose subunits with (α1→6) at the branching points.
Cellulose is a fibrous, tough and water-insoluble substance found in plant cellwalls. It is is a linear unbranched polysaccharide made up of D-glucose units linked together by (β1→4) glycosidic bonds.
Chitin is is the main component of the exoskeletons of athropods. It is a linear molecule composed of N-acetylglucosamine units linked together by (β1→4) glycosidic bonds.
What is the basic building block of all living things?
Answer:
[tex] \huge \boxed{ \mathbb{ \bold{ \purple{ \: cell}}}}[/tex]Explanation:
All the living organisms on this Earth are made up of microscopic units called cells. It is basic structural unit for all the organisms. The cells are the building block of all the living organisms. Our body is composed of trillion of cells. They carry out the functional activities of our life. A cell can be defined as a basic , structural and functional unit of life capable of independent existence. The cell was first discovered by Robert Hooke in 1665 AD. As we know that all the living organisms are made up of cells. These cells are developed as a result of a division of pre-existing cells. All the cells are same in chemical composition and metabolic processes. The function of an organism as a whole is the outcome of combined activities and interactions of the constituent cells. The cell is known as the fundamental , structural and functional unit of life.

O AtRNA template is used to create an mRNA strand.
O An mRNA template is used to create an amino acid chain.
Answer:
[tex]\huge\boxed{Option \ 4}[/tex]
Explanation:
In translation process, the messenger RNA (mRNA) template is used to create amino acid chain by which a protein is formed. Translation is the process of synthesis of proteins from amino acids which the help of mRNA.
The option that best describes something that occurs during translation is an mRNA template being used to create an amino acid chain.
Translation, also known as protein synthesis, is one of the steps in gene expression. It involves the translation of genetic codes in an mRNA molecule to their respective amino acids in the ribosome.
The first step in gene expression is the transcription of genetic information on DNA into codes in the form of an mRNA. The mRNA then undergoes some processing before the genetic codes are translated, with the help of the tRNA which carries the anticodons, in the ribosome.
The codes are not just translated to their respective amino acids but the latter are joined together by peptide bonds to form the primary structure of proteins.

Proteins can buffer a drop in pH by their _____ side groups and can buffer an increase in pH by their _____ side groups.
Answer:NH2 side group and COOH side group.
Explanation:
Proteins can buffer a drop in pH by their NH2 side groups and can buffer an increase in pH by their COOH side groups.
What are Proteins?Large, intricate molecules known as proteins play a variety of vital functions in the body. They are crucial for the structure, operation, and control of the body's tissues and organs and carry out the majority of their job inside cells.
Many thousands of amino acids, which are smaller building blocks of proteins, are linked together in lengthy chains to form proteins. To create a protein, 20 distinct kinds of amino acids can be mixed. Each protein's precise function and distinctive 3-dimensional structure are determined by the order of the amino acids.
Combinations of three DNA building units (nucleotides), which are dictated by the order of genes, are used to code for amino acids.
Therefore, Proteins can buffer a drop in pH by their NH2 side groups and can buffer an increase in pH by their COOH side groups.

water to move to the atmosphere fewer clouds and less
precipitation, which can lead to
Answer:
Increased evaporation and transpiration dries out the ground leaving less water to move to the atmosphere fewer clouds and less precipitation, which can lead to drought conditions.
In some areas evaporation and transpiration from plants can be so high that the amount of water available to move to the atmosphere is significantly reduced. This is usually the case in areas that are lacking in open water resources.
As there is less water moving to the atmosphere, there will be less water condensing into clouds and thus less rain. If this persists, it can lead to a drought.

Desmosomes
*act as rivets to hold adjacent cells together when epithelial tissue moves
Gap junctions
*allow movement of cytosol, ions, and small molecules between animal cells
Plasmodesmata
*openings through the cell walls of plant cells that allow adjacent cells to share materials
Answer:
Tight junctions - prevent liquid from seeping between cells
Desmosomes - act as rivets to hold adjacent cells together when epithelial tissue moves
Gap junctions - allow movement of cytosol, ions, and small molecules between animal cells
Plasmodesmata - openings through the cell walls of plant cells that allow adjacent cells to share materials
Explanation:
1) Tight junctions are one of the cell junctions found in animal cells. Tight junctions function to prevent the flow of liquid materials between cells.
2) Desmosomes are another type of cell junctions whose function is to form a connection between two adjacent cells. The structure formed by this connection confers strength upon the tissues involved.
3) Gap junctions are the most commonly found cell junctions found in animal cells that connects adjacent cells allowing the passage of cytosol, ions and other small molecules in them from one adjacent cell to another.
4) Plasmodesmata is a cell junction found in plant cells. They are small openings lying across the cell wall of plant cells whose function is to connect the cells and facilitate the movement of materials from one cell to another.

In a nutrient medium that lacks histidine, a thin layer of agar containing around 10^9 Salmonella typhimurium histidine auxotroph produces around 13 colonies over a two day incubation period at 37 degrees centigrade. How do these colonies arise in the absence of histidine? The experiment is repeated in the presence of 0.4 micrograms of 2-aminoanthracene. The number of colonies the number of colonies produced over 2 days exceeds 10,000. What does this indicate about 2- anthracene? What can you surmise about its carcinogenicity?
Answer:
Reverse mutations in the colonies enabled to recover the ability to synthesize histidine. The 2-aminoanthracene is a chemical agent that induce mutations and therefore it is potentially a carcinogen.
Explanation:
A reverse (suppressing) mutation is a type of mutation capable of restoring the activity of previously mutated genes. On the other hand, 2-aminoanthracene is an aromatic amine carcinogen capable of inducing hepatic and skin tumors. In this case, 2-aminoanthracene has been used to induce reverse mutations at loci responsible for the synthesis of histidine.

What is 0.55 hectometers expressed in decimeters?
550 dm
b. 5.5 dm
c. 55 dm
d. 0.00055 dm
Answer:
A 550
Explanation:
0.55 hectometers is equivalent to 550 decimeters.
Since 0.01 hectometers and 10 decimeters (1 meters) are both equal to one meter, :550 decimeters (55 meters) are equal to 0.55 hectometers. Thus, option A is correct.
What are hectometers and decimeters?
The International System of Units (SI) defines the hectometer (International spelling as used by the International Bureau of Weights and Measures; SI symbol: hm) or hectometer (American spelling) as a unit of length that is equal to 100 meters and one tenth of a kilometer.
The ruler, which is 12 inches (0.3 m) (in) or 30 centimeters (cm) long and equals one foot or slightly under one-third of a meter, is visible. 100 meters make up a hectometer.
To produce one hectometer or 328 feet (99.97 meters), that would need about 328 rulers. That is a lot of rulers, I must say. Here is a simpler method for recalling a hectometer's length.
Decimeter measurements are uncommon in everyday life. It is simpler to use 0.1 m or 0.5 m when the length is less than a meter because one meter is not a particularly length.
Therefore, 550 decimeters (55 meters) are equal to 0.55 hectometers.
