which shape is both a rectangle and a square
Rectangles are squares too, but not all squares are rectangles. When all four sides of a rectangle are not congruent, that is, when all four sides are not the same length, then a rectangle is NOT a square. Instead, a rectangle will have two pairs of sides, with each pair having two sides that are opposite each other, parallel to each other, and congruent to each other while, at the same time, NOT congruent to the other.
In conclusion, a rectangle is not a square if all four of its sides are not congruent, or if all four of its sides do not match.

Enzymes break apart molecules during digestion by a chemical process known as __________.
Enzymes break apart molecules during digestion by a chemical process known as Enzymatic hydrolysis.
Enzymatic hydrolysis is a procedure in which water molecules are used to help hydrolase-type enzymes break a substrate into reaction products. Each enzyme requires a certain set of reaction conditions (temperature, pH, etc.) for optimum activity.Enzymes are proteins that catalyze chemical processes. They start the reaction, speed up its development, and guarantee that the outcome is consistent. Since the enzyme is unaltered after the reaction, it can catalyze another one.The substrate might be any one of a variety of complex proteins, sugars, or lipids. The interaction of the enzyme with its substrate is fluid and dynamic. Like a lock and key, every enzyme has a specificity for its substrate; this specificity is the enzyme's main function. Enzymes also have secondary activities, or the ability to cleave substrates outside those that were first mentioned, in addition to this well-known activity.Learn more about the Enzymatic hydrolysis with the help of the given link:

One function of the hcl secreted in the stomach is to convert pepsinogen into the active enzyme pepsin. why dont stomach cells simply secrete pepsin instad?
Cells would break down their own cellular proteins if they produced active pepsin.
Cellular Protein- The collection of proteins inside a cell determines its state of health and how well it works. Proteins are responsible for the shape and internal structure of cells, the synthesis of products, the elimination of waste, and routine maintenance.
Pepsin- An enzyme in the stomach called pepsin is utilized to digest eaten food's proteins. The primary cells of the stomach generate pepsin as pepsinogen, an inactive zymogen. The parietal cells in the stomach's lining release hydrochloric acid, which lowers the stomach's pH. At a pH of 1.5 to 2, pepsin is activated.

The best description of the bonds that form polypeptides and the difference between polypeptides and proteins is.
Answer:
Explanation:
A peptide is two or more amino acids joined together by peptide bonds, and a polypeptide is a chain of many amino acids. A protein contains one or more polypeptides. Therefore, proteins are long chains of amino acids held together by peptide bonds.
hope this helps :)
Polypeptides are collections of amino acid chains linked by what are known as peptide bonds. The carboxyl group of one amino acid and the amino group of another amino acid condense, forming these peptide bonds and releasing a water molecule in the process.
The size and complexity of polypeptides and proteins primarily differentiate them from each other. Polypeptides are amino acid chains that are usually less than 50 amino acids long.

Why have more groups within the archaeplastids not developed complex multicellularity?.
More groups within the archaeplastids not developed complex multicellularity due to the fact that evolution is not goal-oriented, complex multicellularity has developed, and each group is successful with its current morphology.
Archaeplastids comprised of many more groups which have no developed multicellularity in complex structures. From fungus to people, every multicellular organism first evolved from a single cell. Before assembling to create multicellular groups, these cells were able to exist on their own for billions of years.
The majority of archaeplastids are single-celled algae. The name “archaeplastid” refers to early plastids. Given that they may have ingested cyanobacteria and acquired chloroplasts through endosymbiosis, this is supported by evolutionary evidence.
In the course of evolution, other eukaryotes may have swallowed up archaeplastids to acquire chloroplasts. Some of the members of this group later developed multicellularity. Therefore, it’s merely a random event that could proceed in any way. The only difference is that Archaeplastida evolved in accordance with their environment and demands.

A protein with a high percentage of aspartate and glutamate residues would be best purified and concentrated with which type of column?.
Anion-exchange chromatography would best purify and concentrate a protein with a high percentage of aspartate and glutamate residues.
Anion-exchange chromatography separates chemicals based on their charges by utilizing an ion-exchange resin with positively charged groups, such as diethyl-aminoethyl groups (DEAE). The resin is covered with positively charged counter-ions in solution (cations). Anion exchange resins attach to charged molecules and dispense the counter-ion negatively. At higher pH levels, anion exchange chromatography is often used to filter proteins, amino acids, sugars/carbohydrates, and other acidic compounds having a negative charge. The intensity of the substance's negative charge determines the binding's tightness between the substance and the resin.
