What point of action can stop the communication between neurons? Other than NA+
Explain
Helpppp please
Answer:
Your brain is a hotbed of electrochemical activity. About 100 billion neurons are each firing off 5-50 messages (action potentials) per second. This activity allows you to process your environment, move your muscles, and even keep your balance! If you touch something slimy, that information goes from your fingertips to your brain, and then your brain says “eww, no!” and sends information to your fingertips telling them to move away. The same thing happens when you trip and you’re about to fall, or a bright light flashes in your eyes. Your brain receives information about where you are in space, or the brightness of the light, and responds accordingly. And it’s in our best interests that this action-reaction process goes quickly – so that we can catch ourselves as we fall, or shut our eyes tight. The process of sending these signals takes place in two steps: along the cell (action potential) and between cells (neurotransmitters).

Which formula is an ionic compound?
NaF
N2
NO2
CO2
Answer:
NaF I took the test, hope this helps. :)
Explanation:
NaF is an ionic compound. Ionic compounds have ionic bonds between the molecules.
What is ionic compound?Because each atom contains a particular combination of protons, neutrons, and electrons, each atom is singular. An atom typically has the same number of protons and electrons.
And while the number of protons in an atom can never vary because doing so would result in the presence of an entirely other element, the number of electrons can occasionally shift.
Adding or taking away electrons from an atom alters the charge of the atom since electrons have a net negative charge by themselves. This is due to an imbalance between the number of protons, which have a positive charge, and the number of electrons.
Therefore, NaF is an ionic compound. Ionic compounds have ionic bonds between the molecules.

What is the initial velocity of the reaction catalyzed by the wild-type enzyme when the substrate concentration is 10 mM?
Answer:
50 micro mol/min
Explanation:
So, we have the following parameters which are going to help us in solving this particular Question or problem;
=> For the wild type enzyme, the value for the Maximum velocity = 100 micromol/min.
=> For the mutant type enzyme, the value for the Maximum velocity = 1 micromol/min.
So, we can determine or calculate the value for the initial velocity for each of the enzyme type by using the formula below;
Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.
Therefore, for the wild type enzyme; the Initial velocity = (substrate concentration × maximum velocity) / substrate concentration + Km.
Initial velocity =( 10mM × 100micromol/min) ÷ ( 10mM + 10 mM ) = 50 micro mol/min.
Initial velocity for the wild type enzyme = 50 micro mol/min.

HURRY PLEASE. List the four types of organic compounds found in all living things and explain why they are important.
Answer:
Explanation:
Four organic molecules make up all of the life on Earth. Organic molecules contain carbon and hydrogen chemically linked to one another in long chains, with carbon as the backbone and hydrogen atoms attached to the carbon atoms. These atoms' ability to attach to one another allows for the creation of innumerable compounds conducive to life. All organisms need four types of organic molecules: nucleic acids, proteins, carbohydrates and lipids; life cannot exist if any of these molecules are missing.
Nucleic Acids
The nucleic acids are DNA and RNA, or deoxyribonucleic acid and ribonucleic acid, respectively. They make the proteins that are present in almost every structure and perform almost every function in your body. DNA has a twisted ladder-like form, while RNA has many different shapes, depending on its function. DNA typically remains within the center, or nucleus, of a cell; RNA can travel throughout the cell to where it is needed. The backbones of both substances consist of alternating molecules of phosphate and sugar. Nucleotide bases make up the "rungs" attached to the backbone. Of the two types of nucleic acids, DNA is more stable, making it less likely to be broken down than RNA. Your genes are made up of DNA, and each gene provides the code for making a specific protein. RNA helps DNA to make these proteins.
Proteins
Proteins are probably the most versatile of all the organic molecules, making up many structures and executing various functions within organisms. Building blocks called amino acids make up proteins. About 20 different amino acids combine to form all of the various types of proteins on Earth. These amino acids all have almost the exact same composition; the only difference is the R group, which differs in each of the amino acids and gives them their uniqueness. When a protein is made, the protein comes together one amino acid at a time within the ribosome -- a structure that houses protein synthesis. Proteins have four levels of structure: The primary structure is the bonding of amino acids to one another; the secondary structure refers to the folds in certain areas within the protein; the tertiary structure is the ultimate three-dimensional look of the protein; and the quaternary structure consists of smaller protein subunits chemically bonded together to form a larger protein.
Carbohydrates
Carbohydrates comprise the largest number of organic molecules in organisms. Basically, carbohydrates are sugars; their origin can be traced to photosynthesis, the process by which organisms such as plants use sunlight to transform carbon dioxide and water into food. The simplest sugar is glucose, a molecule used to provide fuel for many types of organisms, including humans. The sugars found in foods include: fructose in fruits, galactose in milk, maltose in vegetables and sucrose in table sugar. The starch found in whole grains and vegetables is a complex carbohydrate made of chains of simpler glucose molecules. Your body contains an enzyme called amylase, which breaks down carbohydrates in the food you eat into glucose, which your cells can use as energy.
Lipids
Lipids, perhaps better known as fats, come in different forms in your body and contain the most energy of all the organic compounds. When your body burns lipids for fuel, you get more energy than if you burned the other organic molecules. In your body, fats perform many functions, taking the form of phospholipids and cholesterol, both important components of cell membranes; waxes that provide plants and animals with a protective layer; hormones that signal different functions in your body; vitamins that aid in different cell functions; and steroids, which are important in a number of physiological processes. Fats from animals tend to be more viscous than fats from plants.

How do genetic factors, environmental factors, and pathogenic agents affect both individual and public health?
Ans:
genetic factors:
Many conditions and diseases are related to genes in some way. Some mutations may be in a single gene, although most disorders are more complex. Many diseases, such as heart disease and diabetes, are caused by issues with multiple genes in combination with lifestyle and environmental factors.
environmental factors:
Many things in the environment can affect our health. Hazardous substances found in the air, soil and water can originate from a variety of sources, such as agricultural and industrial activities, mining operations, landfills and leaky underground storage tanks
pathogenic factors:
Sometimes bacteria multiply so rapidly they crowd out host tissues and disrupt normal function. Sometimes they kill cells and tissues outright. Sometimes they make toxins that can paralyze, destroy cells' metabolic machinery, or precipitate a massive immune reaction that is itself toxic.

4. Which energy resource, once depleted, is essentially nonrenewable?
O A. Coal
O B. Solar
O C. Biomass
O D. Wind
Help :(
Answer:
The answer would be A. Coal
The energy resource that, once depleted, is essentially nonrenewable is coal, which is present in Option A, as coal is a fossil fuel that takes millions of years to form from the remains of plants and animals.
what is coal?Coal is a fossil fuel that is formed from the remains of plants and animals that lived millions of years ago, and these organic materials were buried under layers of sediment and rock, and over time, heat and pressure caused the organic material to transform into coal. This is a finite resource because the process of forming coal takes millions of years, so the rate at which coal is consumed far exceeds the rate at which it is formed, which means that once coal is depleted, it cannot be replenished within a human timescale.
Hence, the energy resource that, once depleted, is essentially nonrenewable is coal, which is present in Option A.

The diagram below shows the formation of the disaccharide maltose, which occurs when two molecules of glucose undergo a dehydration reaction.
a. Describe the result if a molecule of fructose became bound to glucose instead.
b. Explain how the properties of the molecule that forms might differ from maltose.
Answer:
A. If a molecule of Fructose bonded with Glucose, it would become Sucrose, or Table Sugar, and release a water molecule.
B. It may have the same chemical make-up, but fructose is a pentagonal ring instead of a hexagonal ring.
I know this is almost a year late, but clicking on this question helped me answer the same question.
A water molecule would be released if a fructose molecule joined forces with a glucose molecule to form sucrose, sometimes known as table sugar. Despite having a similar chemical structure, fructose has a pentagonal ring rather than a hexagonal ring.
What are different properties of sucrose and maltose?When two simple sugars are combined, maltose and sucrose are both produced. The primary distinction between maltose and sucrose is that the former is made up of two molecules of glucose.
While the latter is made up of glucose and fructose. Furthermore, sucrose is a non-reducing sugar, whereas maltose is a reducing sugar.
Most sugars are composed of short chains of smaller sugar molecules that act as the building blocks.
Maltose is produced when two molecules of glucose interact. Table sugar, often known as sucrose, is composed of one glucose and one fructose. Maltose can be created during the breakdown of starch, a lengthy chain of many glucose units.
Therefore, both maltose and sucrose differ in their properties.
