20. A research company wants to design a new type of artificial heart valve that will be less likely to be rejected by a person's immune system. Which step in the design process should the company perform before building a prototype of the heart valve?
A. Find test subjects for the new heart valve.
B. Conduct research on existing artificial heart valves.
C. Determine how to manufacture the new heart valve.
D. Evaluate the performance of the artificial heart valve.​

Answers

Answer 1

Answer:

C. Determine how to manufacture the new heart valve.

I think it seems a little obvious (I'm probably wrong)because obviously before doing something important your going to think about how to do it first.

Answer 2

The step in the design process that should the company perform before building a prototype of the heart valve is to determine how to manufacture the new heart valve. Thus, the correct option for this question is C.

What is meant by a Prototype?

A prototype may be defined as a sample, model, or liberation of a product that is significantly built in order to test a concept or process. This term is used in a variety of contexts, including semantics, design, electronics, and software programming.

A prototype is typically utilized in order to determine a new design to increase precision by system analysts and users. If an organization or individual wants to design any type of structural and functional unit, they must require to know its actual mechanism of it.

Then they are allowed to manufacture the concept with regard to their discovery. So, a research company requires to demonstrate how to manufacture the new heart valve with the help of a prototype.

Therefore, the correct option for this question is C.

The four classes of macromolecules are carbohydrates, proteins, nucleic acids, and lipids. These biomolecules can also be referred to as polymers. In turn, we will discuss how these four classes of macromolecules are synthesized in the cell from their constituent building blocks or monomers.

Explanation:

Antibody Classes. Antibodies can be divided into five classes—IgM, IgG, IgA, IgD, IgE—based on their physiochemical, structural, and immunological properties. IgGs, which make up about 80 percent of all antibodies, have heavy chains that consist of one variable domain and three identical constant domains.

Answer:

Antibodies are proteins. An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shape protein produced by plasma cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses

It is not the number of different nucleotides, but the ________________ that is important in the ability of DNA to code for all the variability of organisms.

What are two ways in which cells use the energy temporarily stored in ATP?

Answers

Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways

The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.

What is Active transport?

Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.

ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.

Answer: All substances are built from

oxygen

Explanation:

All substances are built from atoms as atoms are the basic building blocks of matter and are the smallest units of a chemical element. The correct option is D.

Atoms form the basis of all compounds. The fundamental building blocks of matter, atoms are the smallest units of a chemical element that nonetheless retain that element's chemical characteristics.

Atoms from various elements combine chemically to produce compounds, however compounds themselves are not the basic building blocks.

Although oxygen is an element that is present in several substances, it is untrue to say that oxygen is the primary component of all substances.

Although metals are a specific kind of element, not all substances are made of metals. Thus, the most correct response is that all substances are composed of atoms.

What is nucleotide?

It is the sub units and buIlding blocks of DNA. It is made up of a five-sided sugar, phosphate group and then a nitrogen base.

These groups make the backbone of the DNA helix. If you look at a DNA helix, they make the side of the ladder or the side portion. They connect to a nitrogen base which make the steps of the ladder.  The type of sugar that is used in a DNA helix is called deoxyribose.

Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.

Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine. Purines on the other hand make 5-sided and 6-sided rings.

building blocks, how can there be so many different types of proteins with different
functions?

Answers

Answer:

The basic building blocks of proteins are called amino acids. In proteins, amino acids are arranged into a linear molecule called a polypeptide chain. Some proteins only consist of a single polypeptide chain while more complex proteins are made out of multiple polypeptide chains bonded together.

Explanation:Proteins are formed out of long linear molecules of amino acids called polypeptide chains. The identity and function of a protein are determined by its sequence of amino acids and the 3-D structure of its polypeptide chains. Amino acids are stored in DNA in the form of sequences of nucleotide bases.
