Glucose is a building block of carbohydrates. Which of these best describes glucose?
A. nucleotide
B. protein
C. monosaccharide
D. lipid
Answer:
monosaccharide
Explanation:
Glucose is called a simple sugar or a monosaccharide because it is one of the smallest units which has the characteristics of this class of carbohydrates.
Glucose is the simplest monosaccharide which cannot be broken down further. Thus, option C is correct.
What is Glucose?Glucose is the primary component of carbohydrates. Glucose is a monomer made up of carbon, hydrogen and oxygen. Molecular formula of glucose is C6H12O6.
The functional group in glucose is an aldehyde present at the first carbon atom.
Glucose is called monosaccharides because it cannot be hydrolysed further. It is the simplest carbohydrate also referred as simple sugars.
Glucose molecules are chiefly linked together forming a glycosidic bond by removal of water molecule and form a disaccharide.
Glucose is chiefly produced by plants during the process called photosynthesis.
Glucose is the key component in metabolism. It provides energy to the body cells to carry out physiological activities. Glucose is found in blood.
Excess of glucose in the blood results in a medical condition called diabetes. It can be life threatening if not managed on time.

Describe the difference in how a monosaccharide and polysaccharide are digested
Answer:
polysaccharides from cells walls make up the fiber humans eat, while monosaccharides provide the sweetness in food. As humans eat, chewing breaks down polysaccharides into smaller particles that eventually, through digestion, yield up the simple monosaccharides that can pass into the bloodstream

Which toy car had the greatest applied force?
A 1
B 2.
с 3
D4
Answer:
the answer is 4
Explanation:
i dont know how to explain it but i took the test and it was right.
The car with the greatest applied force is : ( D ) Car 4
Given that :
Force applied is calculated as : Mass * acceleration
Calculating the force applied on each carFor Toy car 1
mass = 0.19
acceleration = 0.15
Force = 0.19 * 0.15 = 0.0285 N
For Toy car 2
mass = 2.0
acceleration = 1.5
Force = 2 * 1.5 = 3 N
For Toy car 3
mass = 0.25
acceleration = 0.21
Force = 0.25 * 0.21 = 0.0525 N
For Toy car 4
mass = 2.5
acceleration = 3
Force = 2.5 * 3 = 7.5 N
From the answers above the car with the greatest applied force is car 4 with a force of 7.5 N
Hence we can conclude that The car with the greatest applied force is : ( D ) Car 4

What term best describes region “B” of the phospholipid model above?
Answer:
Hydrophobic
Explanation: The phospholipid has a chagred head (Phosphate region) and hydrophobic tails. Lipids are usually nonpolar and hydrophobic. That is why the tails are oriented towards the interior of the membrane.
The two parts 3 and 4 in the region B of the phospholipid model are 3- saturated fatty acids and 4- unsaturated fatty acids.
What is phospholipid model ?
Phospholipids are a class of lipids having significant role in the construction of cell membranes. It is composed of a hydrophilic head with a phosphate group and a hydrophobic tail with fatty acids end.
The fatty acids present in the phospholipid bilayer , are of two types, Saturated and unsaturated. Fatty acids chains without any double bonds or triple bonds are called saturated fatty acid.
Whereas, fatty acid chain with double bonds or triple bond are called unsaturated fatty acids. These two fatty acids chain creates the hydrophobic tail of the phospholipid bilayer.
Hence the region marked as B is saturated and unsaturated fatty acids.

Explanation:
If your hair is long enough, it could easily drift into the flame and catch on fire.
Answer:
D. Loose hair
Explanation:
Loose hair would be the most likely to cause an accident with an open flame.
Especially if the hair is long, it can dip down into the flame and catch on fire.
The other objects would not be interacting with the flame because they would be far away, while loose hair can reach into the area where the flame is.

A researcher observes the enzymatic polymerization of an organic molecule in a cell. Which enzyme is
MOST likely responsible for catalyzing the reaction?
A. a protein
O B. a nucleic acid
O C. a lipid
D. a carbohydrate
Answer:
A. a protein
Explanation:
Proteins function as enzymes in most of the catalyzing reactions, that increases the rate of reaction within cell.
Proteins are consist of multiple numbers of amino acids and the twisting and folding amino acids provide a unique identity to enzymes. Not all the proteins are enzymes but all the enzymes are proteins.
For example: Trypsin, Pepsin, and Lipases.
Hence, the correct option is "A. a protein".

What would happen to a plant cell if it placed in water?
Answer: It really depends on if the water solution is hypotonic, hypertonic, or isotonic. If it is hypotonic (water with less salt or other dissolvent in it than the cell), you can expect the cell to take in water and expand. If the water is isotonic (about the same amount of dissolvent in it as the cell) just about nothing will happen, or if the water is hypertonic (more dissolvent in the water than the cell) the water can seep out of the cell, and into the water.
