Transport of Na+ from a place of low concentration to a place of higher concentration Passive transport is an awesome methodology for moving particles into or out of a cell. It's shabby, it's simple, and all the cell needs to do is stay there and let the particles diffuse in. But...it additionally doesn't work in each circumstance. For example, assume the sugar glucose is more concentrated a cell than outside. If the cell needs more sugar in to meet its metabolic needs, how might it get that sugar in? Here, the cell can't import glucose with the expectation of complimentary utilizing diffusion, on the grounds that the regular inclination of the glucose will be to diffuse out as opposed to streaming in. Rather, the cell must get more glucose atoms through active transport. In active transport, dissimilar to passive transport, the cell consumes vitality (for instance, as energy) to move a substance against its concentration slope.

Molecular geometry is the shape of the molecule based on how the atoms are arranged. The shape of the molecule affects many different things including its color, how well it can magnetize thing, how it reacts, its polarity and the activity involving biology. Molecules do bond and this bonding has to do with its shape. The shape of the molecules is tetrahedral. A tetrahedron is shaped like a pyramid. It has four sides and is three-dimensional. It could also be called a triangular pyramid. However, tetrahedrons can include six edges and four vertexes which means that it has four points or corners. If you have a piece of paper, then you can make a tetrahedron. So, a molecule is shaped like a triangular pyramid.

The correct answer is FeO(s) + 2H (aq) → H2O(l) + Fe2(aq), with CIO4- as a spectator ion. For those who haven’t studied chemistry past what is offered in most American high schools, a spectator ion is pretty cool. The ion goes through the reaction, and comes out without a scratch. Therefore, it remains unchanged in the equation, and is often placed to the side of the final equation. In this instance, CIO4- is the spectator ion in our equation. As for getting the balanced net ionic equation, this is just another way to say that the equation has been balanced, and it shows the states of each ion. So, “s” would be a solid, “aq” would be aqueous, and “l” would be a liquid.

Myoglobin is an iron and oxygen binding protein that is found in the muscle tissue of vertebrates and in nearly every mammal. Myoglobin is closely related to hemoglobin which is the iron and oxygen binding protein that is found in blood. The function of myoglobin is to bind oxygen when the concentration of oxygen is very high in the lungs. There is still actually a lot that is unknown about the functions of myoglobin. Studies conducted with mice, for example, have shown that mice can make up for the loss of myoglobin and still function perfectly well. It is unknown if humans are exactly the same or not.

Water is a molecule that is found abundantly on Earth. It consists of two hydrogen atoms and one oxygen atom. Due to what water is made of, it can bond to other substances including acids. It can also separate other things due to its nature and consistency. The oxygen atom is interesting including that it is electronegative. This means that it attracts certain electrons. In order for the charges to attract, they must be opposite charges. Therefore, the water molecule has a positive and negative ends. Water is a liquid at room temperature and it freezes when it reaches 32 degrees Fahrenheit or zero degrees Celsius. Water boils at one hundred degrees Celsius or 212 degrees Fahrenheit. This is for fresh water.

The correct answer to this question is B. H2 is the molecular formula of Hydrogen, a colorless, odorless, highly flammable gas. One Hydrogen atom has one electron and is the first element on the Periodic Table of Elements. The molecular polarity of H2 is linear and nonpolar. An H2 molecule is made up of two hydrogen atoms, and they share the same electronegativity (or tendency to attract other electrons). A symmetical molecule looks the same no matter which way you turn it or look at it, hence the name. The symmetry of a molecule affects how it racts to light and other molecules.

Diluting with waterBy diluting the solution with water, it makes it more difficult for the enzyme and substrate to find each other. (There is more space for them to have to float through to find each other - for example, say you lose your binder. It would be much easier to find your lost binder if you know you lost it in your bedroom vs. if you lost it at school because the school campus is much bigger than your bedroom.)

NF3 is the chemical equation for nitrogen trifluoride. It makes a Y-shape if you diagram it out with the nitrogen in the middle and the three fluoride molecules around it. It is considered a polar molecule, with an asymmetrical distribution of charges. This is because fluoride is the most electronegative molecule on the planet! It will cling to any negative charge it finds. However, at a more basic level, a polar molecule has a charge while a nonpolar molecule has none at all because every atom in the molecule has an equal balance of protons and electrons. For example, water is a polar molecule, while something like table salt is nonpolar. There are, of course, other reasons for this, but there is not enough room to explain them here.

An acid can be determined using a pH scale. When the substance or element scores seven or less on the pH scale, then it is considered to be an acid. When the substance or element scores more than seven on the pH scale, then it is considered to be a base. An acid by definition is one in which it can donate a proton. A base is the opposite of the acid. It is the substance that can take a proton and not donate it. An acid base neutralization is one in which both the acid and base on a reaction do react equally. Both acids and bases in the equation are equal on both sides of the chemical equation.

Making an ester linkage that links the fatty acid carboxyl groups to the hydroxyl groups in glycerol. There are two distinct kinds of fatty acids, saturated and unsaturated. In a saturated fatty acid, it has the most extreme number of hydrogen ions plausible, in this manner there are no dual bonds. There are just single bonds. Since saturated fatty acids are just single bonds, it can pack all the more firmly together at room temperature and this makes it a strong at room temperature. A perfect description of fatty acid is spread. An unsaturated fatty acid has one all the more dual bond. These dual bonds make a crimp in the hydrocarbon tail, which consequently brings about looser pressing. At room temperature, it is a fluid. Phospholipids are found in natural membranes. The fatty acids give a hydrophobic boundary, though the rest of the molecule has hydrophilic properties. Phospholipids immediately shape lipid bilayers due to amphipathic nature of lipid molecules. Phospholipids are found in all cell membranes So the answer to this question is fat.

I do not understand how the answer is not all of the above, I calculated all of those answers.

Combustion is known to be the oxidation of an organic compound which means that the compound will turn into carbon dioxide and water molecules. Oxidation is almost the same but the main difference is the addition of oxygen with an element. You will know if combustion is taking place because of the presence of heat and the item may also ignite and show light. When oxidation takes place, there will be no heat. It should be noted that combustion and oxidation are not the same processes. They have differences that will make it easier for you to determine what process has taken place.
