Which of the following are the large molecules that are broken down into smaller molecules during digestion?
Answer:
Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular 'building blocks' within the food together. For example, proteins are broken down into their 'building block' amino acids.
Explanation:
Fats, proteins, and carbohydrates are macromolecules that are broken down into smaller molecules during digestion.
What is digestion?The term "digestion" describes the process by which food is broken down into smaller pieces that can be absorbed into the bloodstream.
The breakdown of food into smaller bits, known as mechanical digestion, takes place in the mouth. Chemical digestion, on the other hand, takes place in the gastrointestinal tract when the meal is broken down into small molecules by digestive enzymes. Digestion begins from the buccal cavity.
Macromolecules such as fats, carbohydrates, and proteins, are broken down into their monomeric form. Thus, this four are the large molecules broken down into smaller molecules during digestion.

Explanation:
An engineer is developing a new prosthetic leg to help patients who have lost limbs to walk. The engineer is focused on making the best device possible to address this medical need. The current device design will cost $I0,000 to manufacture, but the cost ofthe item cannot exceed $8,000. How should the engineer approach this problem using the engineering design process?
Answer:
the engineer needs to consider alternatives for all of the areas of the design process that are considered costs
Explanation:
In order to accomplish this, the engineer needs to consider alternatives for all of the areas of the design process that are considered costs. This includes materials, marketing, manufacturing, etc. Many times the material that is being used alone can skyrocket the cost of making a specific product. Therefore changing to a new material may lack some of the wanted benefits but will reduce the overall cost. Manufacturing techniques can also drastically reduce costs by simplifying the process you save on electricity costs and worker wages, while still outputting the same amount of product, which in term reduces the overall costs of the item.

When placed in water, oil does not dissolve and stays separate. This means oil is_____ and ____.
Answer:
when placed in water, oil does not dissolve and stays separate. this means oil is immiscible and inorganic
Explanation:
When placed in water, oil does not dissolve and stays separate. This means oil is a non-polar and hydrophobic substance.
What are oils?Oils are organic compounds. They are nonpolar chemical substances that are made up of hydrocarbons. They're flammable, and they're extracted from vegetables plants, and animals.
Oils are not soluble in water because they are hydrophobic in nature, doubt a layer of oils is made of made up of a hydrophobic chain that is insoluble in water.
Substances are nonpolar substances are those substances which are insoluble in water. Oil is one of them. Polar substances are dissolved in water because they have hydrophilic ends.
Thus, oil does not dissolve in water and remains separate. Oil is a non-polar, hydrophobic substance, according to this.

A student wins a trophy. It is a metal cup on a black plastic base. The student cleans the trophy. She holds one of the metal handles and rubs the rest of the trophy with a dry cloth. Why the plastic base does becomes negatively charged? B) The metal cup does not become charged when she rubs the trophy. Suggest why the cup does not become charged.
Answer:
In this given statement , the plastic base becomes negatively charged because plastic is an insulator . And the metal cup does not become charged because metal is a conductor.
Explanation:
Reason behind , why plastic base becomes negatively charged -: When a plastic base is rubbed with a dry cloth in the metal trophy, electrons are shifted from one material to the other. Thus, the substance that gains electrons (which is the plastic base) becomes negatively charged. thus , the plastic is an insulator , which causes charge (negative ) by rubbing.
Reason behind , why the metal cup does not become charged -: The metal cup is a conductor, and the surplus charge on the metal flows to the person who charges the cup and to the ground so that it is not charged. Thus, rubbing a metal can trigger hand\finger injury because metals generate excess heat in rubbing .

Testosterone is a small steroid hormone that is important in cell signaling. Which of the following indicates where testosterone enters a cell and why it is able to cross at that point?
А
1, because testosterone is nonpolar and can diffuse through the membrane.
B
2, because testosterone covalently binds to a surface protein and transports into the cell.
C3, because testosterone dissolves in water and flows through the channel
D
4, because testosterone is filtered out of the extracellular fluid and taken into the cell by endocytosis.
<
Answer:
A
Explanation:
explanation is given in answer
Testosterone is a steroid hormone. It is a primary sex hormone. It plays key role in the development of male reproductive tissues such as testes and prostate.
Testosterone is lipophilic signaling molecule. The plasma membrane consist of lipid bilayer so testosterone diffuse through the lipid bilayer and enters the cell.
So, the answer is option A because testosterone is nonpolar and can diffuse through the membrane.
other options-
B because testosterone covalently binds to a surface protein and transports into the cell- incorrect. Testosterone doesn't binds to a surface protein and transports into the cell, it diffuses through the cell membrane.
C because testosterone dissolves in water and flows through the channel-incorrect. Testosterone is nonpolar.
D because testosterone is filtered out of the extracellular fluid and taken into the cell by endocytosis-incorrect. Testosterone is not filtered out of the extracellular fluid and it is not taken into the cell by endocytosis.

The monomer of DNA is a nucleotide. The monomer of glucose is carbon, hydrogen, and oxygen.
What are monomers and polymers?The simplest form of polymers is monomers. To create polymers, each monomer is combined. Usually, a double bond or triple bond holds the monomer together.
Typically, monomers contain two free electrons that pair together and create a double bond among themselves. The monomers of cellulose are an example of a monomer and contain glucose.
A monomer is a molecule that, when combined with additional monomers of the same kind, can create a polymer, such as glucose (C6H12O6). A biological polymer made of several -glucose units is cellulose, which serves as an illustration of this.
Therefore, the monomer of DNA is a nucleotide. The monomer of glucose is carbon, hydrogen, and oxygen. The monomer of their polymers is matched in the added picture.
