Answer:

Each of the reaction must take place three (3)times

Explanation:

The Calvin cycle occurs in the stroma of the chloroplast using the energy generated during the light dependent phase of photosynthesis.

In the stroma, Ribulose -1,5 bisphosphate carboxylase catalyses the addition of one carbon dioxide molecule to ribulose -1,5- bisphosphate to form an unstable hexose compound of 2-carboxy 3-keto 1,5 -bisphosphoribotol which breakdown to form 2 molecules of 3-phosphoglycerate. The latter is them phosphorylated by phosphoglycerate kinase using two ATP and finally glyceraldehyde 3- dehydrogenase enzyme catalyses NADPH reduction of 1,3bisphosphoglycerate to glyceraldehyde 3-phosphate. 3 molecules of carbondioxide yielded 6G3P and five is used to generate RuBP and one molecule of G3P left.

Explanation:

Rats and mice are both rodents, so look similar - the biggest difference is their size. Rats are larger and heavier while mice have smaller slender bodies. Mice also have long slender tails (for their body size) covered in hair compared to rat tails which are shorter, thicker and hairless

Classify each of these statements as always true, at; sometimes true, st; or never true, nt. 11. the rate at which a solute diss
photoshop1234 [79]
It is always true that the rate at which a solute dissolves can be increased by grinding. The smaller the solute the easier it will dissolve in the solvent, while other facts play into the rate at which a solute dissolves in a solvent, a major part of this is also how small the solute is. You can think of how rock salt is harder to dissolve in water compared to finely ground salt.

It is sometimes true that as the temperature of a solvent decreases, the solubility of a solute increase. The reason for this is that for liquids and solids as temperature increases the solubility increases but for gasses, as the temperature increases the solubility decreases.

It is always true that stirring a solute when adding it to a solvent should increase the rate of its dissolving. however, this will not increase the amount that is able to be dissolved in the solution.

It is never true that Henry's law states that the solubility of a gas in a liquid is a function of temperature. Henry's law is a gas law that was determined by William Henry in 1803. The law dictates that when in constant temperature the amount of gas that dissolves in a given volume of a liquid is proportional directly to the partial pressure of the gas at equilibrium with the desired liquid. In simpler terms, the solubility of the gas in a certain liquid is proportional to the partial pressure of the gas above the liquid.

It is always true that two liquids that dissolve in each other are miscible. Miscibility is described as the property of liquids and other substances to mix in all proportions and forming homogeneous solutions.

Compounds with high melting points have _____
solong [7]

Answer:

C) Ionic bonds

Explanation:

The ionic bonds are the strongest bond, it occurs when a metal donates electrons and a nonmetal gain these electrons. They'll be together by electrostatic force.

Metallic bonds it the second strongest bond, it occurs between metals, which loses electrons. It's an electrostatic force, but weaker than the ionic compound because it occurs between the cation and the electron.

Covalent bonds are the weakest bond. It happens between metals and nonmetals, or nonmetals and hydrogen or between atoms of hydrogen. The force that joins the atoms depends on the polarity of the molecule. Polar molecules have dipole forces, nonpolar molecules, induced dipole forces. Also, hydrogen makes special dipole forces with nitrogen, oxygen, and fluorine, called hydrogen bond.

As the stronger is the force, as difficult it will be to break it. So, ionic bonds will demand more energy to become gas, and have high melting points.

3.200 x 109 has how many sig figs?
emmasim [6.3K]

Answer:

It has 4 significant figures

Explanation:

Notice the use of scientific notation to indicate that there are two zeros which should be significant. If this number were to be written without scientific notation (3,200,000,000) the significance of those two zeros would be lost and you would - wrongly - say that there were only two significant figures.
