Answer:

A model from which later versions are developed.

Explanation:

A prototype is the rough draft of something in a sense, it is not yet complete and is often only the most basic idea to be expanded on in later versions.

The best definition for a prototype is a model from which later versions are developed. Therefore option D is correct.

A prototype is an early or preliminary version of a product, system, or design that is created to test and evaluate its functionality, features, and feasibility. It serves as a proof of concept and helps in identifying any flaws or areas that require improvement before the final product is developed.

The final product, which has undergone extensive testing and redesign, does not accurately define a prototype because a prototype is not the final product but rather an initial version created for testing and refinement.

Therefore, the most accurate definition, emphasizes that a prototype is a model or early version of a product or system that serves as a foundation for the development of subsequent versions based on testing and feedback.

Answer:

electron and nuetrons

The molecules NADH and FADH₂ will carry the electrons to the electron transport chain.

These electron carrier molecules (NADH and FADH₂) are produced during the breakdown of glucose and other energy-rich molecules in the preceding steps of cellular respiration. They carry the high-energy electrons derived from these molecules to the electron transport chain, which is embedded in the inner mitochondrial membrane in eukaryotic cells.

The electrons passed through the electron transport chain ultimately combine with molecular oxygen to form water, which is the final electron acceptor in the chain.

Answer:

Acquired traits are due to changes in the life style, injury, loss of body parts, disuse of some body parts. These are the traits which occur in the somatic cells. Changes in the somatic cells are not passed on to the offspring belonging to next generation. Hence acquired traits cannot be passed on to next generation.

Explanation: The car with the smaller mass will require less force to stop than The car with the larger mass that is it

The car with the smaller mass will require less force to stop than the car with the larger mass.

The law of inertia or Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.

This law is called the law of inertia because it depends on mass of the object.

The object with more mass will required more force to be stopped while the object with less mass will require less force to be stopped.

Thus, the car with the smaller mass will require less force to stop than the car with the larger mass.

D. Krebs Cycle

Explanation:

Hope this helped.

The answer to this question is Krebs Cycle.  

Krebs cycle. A series of chemical reactions that occur in most aerobic organisms and are part of the process of aerobic cell metabolism, by which glucose and other molecules are broken down in the presence of oxygen into carbon dioxide and water to release chemical energy in the form of ATP.

Overview of the Krebs or citric acid cycle, which is a series of reactions that takes in acetyl CoA and produces carbon dioxide, NADH, FADH2, and ATP or GTP.

The Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate). This produces citric acid, which has six carbon atoms. This is why the Krebs cycle is also called the citric acid cycle.May 15, 2020

D it is The Grassland

Answer:

There are 20 different standard L-α-amino acids used by cells for protein construction. Amino acids, as their name indicates, contain both a basic amino group and an acidic carboxyl group. This difunctionality allows the individual amino acids to join in long chains by forming peptide bonds: amide bonds between the -NH2 of one amino acid and the -COOH of another. Sequences with fewer than 50 amino acids are generally referred to as peptides, while the terms, protein and polypeptide, are used for longer sequences. A protein can be made up of one or more polypeptide molecules. The end of the peptide or protein sequence with a free carboxyl group is called the carboxy-terminus or C-terminus. The terms, amino-terminus and N-terminus, describe the end of the sequence with a free α-amino group.

The amino acids differ in structure by the substituent on their side chains. These side chains confer different chemical, physical, and structural properties to the final peptide or protein. The structures of the 20 amino acids commonly found in proteins are shown in Figure 1. Each amino acid has both a one-letter and three-letter abbreviation. These abbreviations are commonly used to simplify the written sequence of a peptide or protein.

figure1-Protein-Structure

Depending on the side-chain substituent, an amino acid can be classified as being acidic, basic or neutral. Although 20 amino acids are required for synthesis of various proteins found in humans, we can synthesize only ten. The remaining 10 are called essential amino acids and must be obtained in the diet.

The amino acid sequence of a protein is encoded in DNA. Proteins are synthesized by a series of steps called transcription (the use of a DNA strand to make a complimentary messenger RNA strand – mRNA) and translation (the mRNA sequence is used as a template to guide the synthesis of the chain of amino acids which make up the protein). Often, post-translational modifications, such as glycosylation or phosphorylation, occur which are necessary for the biological function of the protein. While the amino acid sequence makes up the primary structure of the protein, the chemical/biological properties of the protein are very much dependent on the three-dimensional or tertiary structure.

A change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.

In conclusion, a change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.
