Celery stalks are inflated by pure water flowing through them, similar to how Lysol is sprayed in one area and gradually detected in another.
What is Lysol's mode of action?EDTA acts on Mg++ to disrupt the membrane. The cell wall becomes more permeable as a result. Since bacteria's cell walls are negatively charged, positively charged cations such as quaternary ammonium compounds are "attracted" to them (QAC). QACs diffuse through the cell wall after adhering to the cell surface.

What is the major organs and structures of the integumentary system?
The major organ of the body that physically separates the internal environment it protects and maintains from the exterior environment is the integumentary system. The epidermis, dermis, hypodermis, related glands, hair, and nails are all a part of the integumentary system.
The largest organ in the body is the skin. The integumentary system is made up of the skin and its byproducts, including the hair, nails, perspiration, and oil glands. Protection is one of the skin's primary roles. It shields the body from environmental dangers like temperature, toxins, and pathogens.
The hair, skin, nails, and exocrine organs are the integumentary system's organs (e.g. sudoriferous, sebaceous, ceruminous glands). In addition to other functions, these organs play a critical role in the protection of many bodily parts.

Why scientists concluded that the instructions for species characteristics were carried in dna
Answer:
Explanation: Deoxyribonucleic acid is said to contain instructions for species characteristics because it carries the information that characterizes an individual.
DNA is made up of Nitrogenous bases that are unique codes specified by an individual and no two people have the same DNA.
Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains a gene that helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.
Several lines of evidence from various fields of biology and genetics have led scientists to the conclusion that the instructions for species characteristics are carried in DNA.
To begin with, it has been discovered that the offspring of living organisms resemble their parents in many ways. This is true for traits like eye color, hair color, height, and many others. This observation implies that some kind of information or instructions must be passed down from generation to generation.
Second, research into inheritance patterns in plants and animals has revealed that certain traits are passed down in a predictable manner from generation to generation. This resulted in the development of Gregor Mendel's laws of inheritance in the nineteenth century, which established that genetic traits are carried on discrete units known as genes.
Third, using advanced microscopic techniques, scientists discovered that the nucleus of a cell, which contains the genetic material, is made up of thread-like structures known as chromosomes. Further research revealed that chromosomes were made of a chemical substance known as DNA (deoxyribonucleic acid).

Explanation:
which member of kingdom protista is the closest relative to the land plants? A) dinoflagellates B) diatoms amoeba spp. C) rhodophytes D) chlorophytes
The member of Kingdom Protista that is the closest relative to the land plants is:
D) Chlorophytes
Chlorophytes, also known as green algae, are thought to be the most closely related to land plants. This is due to the fact that they share many characteristics with terrestrial plants, such as the presence of chlorophyll a and b, the ability to perform photosynthesis, and the use of cellulose as a structural component of their cell walls.
In fact, some green algae species are so similar to land plants that they are referred to as "proto-plants" at times. It is thought that land plants evolved from a type of green algae, possibly via endosymbiosis, a process in which one organism is taken up by another and they evolve together to form a new organism.
While other Kingdom Protista members, such as dinoflagellates, diatoms, and rhodophytes, perform photosynthesis, they are not as closely related to land plants as chlorophytes.

phospholipids in the cell membrane could be separated experimentally according to their differences in: charge, mass
Why is there a difference only in charge and mass?Amphipathic molecules with a hydrophilic head and a hydrophobic tail make up phospholipids. They arrange themselves in a bilayer in the cell membrane, with their hydrophilic heads towards the aqueous environment and their hydrophobic tails facing one another. It is not possible to effectively separate phospholipids because of the small changes in charge and mass between them. Nevertheless, phospholipids can be separated using a method known as thin-layer chromatography in accordance with changes in their solubility (TLC). TLC divides molecules based on how differently they can interact with stationary and mobile phases. In TLC, distinct components in a mixture are interacted with using a stationary phase coated on a plate, and they are moved along the stationary phase using a mobile phase.

A. Koshland
B. Pauling
C. Pasteur
D. Monod, Wyman and Changeux E. All of these
The sequential model for allosteric enzymes was proposed by: Koshland option A
According to this paradigm for allosteric control of enzymes, multimeric protein subunits have two conformational states. Ligand binding triggers conformational changes in the multimeric protein's other subunits.
Although the subunits undergo conformational changes individually (as contrast to the MWC model), the switch of one subunit increases the likelihood of the other subunits changing by lowering the energy required for following subunits to undertake the identical conformational shift.
The binding of a ligand to one subunit in elaboration modifies the structure of the protein, making it more thermodynamically favorable for the other subunits to flip conformation to the high affinity state.

The blood carries lipoproteins, which are spherical particles consisting of lipids and proteins, to the cells all over your body. Two lipid types that can be present in lipoproteins are triglycerides and cholesterol. These lipoproteins are essential for the small intestine's ability to absorb and transport dietary lipids, as well as for the movement of lipids from the liver to peripheral tissues and from those tissues back to the liver and gut (reverse cholesterol transport).

To precisely regulate the pH levels of blood and other fluids, your body is always at work. The acid-base or acid-alkaline balance is another name for the pH balance of the body. For optimal health, the appropriate pH values are required. The pH range of your blood is typically 7.35 to 7.45. In other words, blood is naturally somewhat basic or alkaline. If the pH of your blood falls below 7.35 and it becomes excessively acidic, you are in acidosis. Alkalosis occurs when your blood pH rises above 7.45 and becomes excessively alkaline. Lungs and kidneys are the two primary organs that assist in maintaining blood pH equilibrium.

It can be affected during ER stress (1) and severe hypoxic states (3).
What is ribosomal protein synthesis?Ribosomal protein synthesis is the process by which ribosomes, the cellular structures responsible for protein synthesis, synthesize their own constituent proteins using instructions encoded in messenger RNA (mRNA) molecules.
During ER stress, the unfolded protein response (UPR) can be activated, which may lead to a decrease in global protein synthesis, including ribosomal protein synthesis. This is because the UPR is designed to reduce the load of protein folding in the endoplasmic reticulum (ER), where ribosomes are located, in order to alleviate ER stress.
During severe hypoxic states, there may be a decrease in ribosomal protein synthesis due to reduced oxygen availability, which can impact the function of ribosomes and their ability to synthesize proteins.
