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.

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!

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

4. Root cells of plants take in some minerals from the surrounding soil by spending
energy. After the plant obtains enough minerals to maintain health, the plant will
continue to absorb minerals from the soil. Which reason best explains why root cells
need to spend energy in order to transport some minerals into cells?
Answer:
i know its 3
Explanation:
yes buddy
After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil.
This is because Mineral concentration is higher in root cells than in the surrounding soil. Thus option D is correct.
What are the effects of minerals do plants growth ?
For a better growth plants need minerals, can be absorbed through the roots by active transport in the form of mineral ions.
Minerals have a major role in electron transport, enzyme activation, development, maintenance of structural components etc.
The two most essential minerals are magnesium ions and nitrate ions needed for proper growth of plants.
Beside this various fertilizer are used like Nitrogen fertilizers which increase the growth as well as high yield of the crops.
Excess use of mineral cause mineral toxicity, for example eutrophication happens when excess nitrate enters into aquatic system causes the death of aquatic animals.

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.
