Which phrase best defines a prototype?
the final product, which has undergone extensive testing and redesign
a model that has been redesigned and retested several times
the criteria established to help solve a problem
O a model from which later versions are developed
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.

What is the difference between a eukaryote and a prokaryote in terms of what they have within in them?
Answer:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.
Two cars with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time to stop?
F- The car with the smaller mass will require less force to stop than the car with the larger mass.
G- The car with the larger mass will maintain its velocity while traveling down the hill.
H- The car with the smaller mass will take longer to stop than the car with the larger mass.
J- The car with the larger mass will have less inertia than the car with the smaller mass.
Please mark answer and Give explanation
Answer:
F
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.
What is law of inertia?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.

What is the job of proteins in the plasma membrane?
Answer:
distribution of drugs
Explanation:
Proteins in the cell membrane play a role in many other functions, such as cell signaling, cell recognition, and enzyme activity. Carbohydrates. Carbohydrates are also found in the plasma membrane; specifically, most carbohydrates in the membrane are part of glycoproteins, which are formed when a carbohydrate attaches to a protein.
Answer:
Transport nutrients
Explanation:
For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location
Which organisms synthesize carbohydrates, and in which cell organelle(s) does this synthesis occur?
a. animals in mitochondria
b. plants in mitochondria
c. plants in chloroplasts
d. animals and plants in mitochondria

plz help im dumb lol also i know it might be an easy awnswer its just i dont know for sure
Answer: it reproduces by cell division
the answer should be ..............
D. uses mitosis
Explanation: here is the Wikipedia explanation im not good at explaining
Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other conditions) are called dimorphic fungi.
Answer:
Is very fast
Explanation:
First of all, you're not "dumb"!
Yeast reproduction happens relatively quickly (in a matter of hours, not a matter of days). It CAN occur by mitosis, but most often occurs by a process called budding.
Humans have a "slow" reproduction - it takes 9 months just to produce a single organism!

Which would probably have the greatest effect on a protein's function—a change to the primary, secondary, or tertiary structure? Explain your answer.
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.
The primary structure of a protein refers to the linear sequence of amino acids within a polypeptide chain.A change in the protein primary structure will change protein properties and likely will also alter their functions.The secondary structure of a protein refers to the specific arrangement of groups of amino acids. The most common types of secondary structures in proteins include alpha helix and beta sheets.The tertiary structure refers to the three-dimensional shape of the protein. There are two major main classes of protein tertiary structure: fibrous and globular.The quaternary structure refers to the association of different protein subunits to form a multimeric protein.In conclusion, a change to the PRIMARY structure WILL HAVE the greatest effect on a protein's function.

what are acquired traits why are the streets generally not inherited over generation explain
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.
