Why does the mass of a substance remain the same after a chemical reaction

Answer:

Even in a chemical reaction when atoms interact and create new products, mass is conserved. This is because the new substances created are composed of atoms that were present in the reactants. The atoms from the reactants come apart, rearrange, and re-bond in a different arrangement to form the products.

A series of Hfr strains that have genotype m+ n+ o+ p+ q+ r+ are mixed with an F− strain that has genotype m− n− o− p− q− r−. Conjugation is interrupted at regular intervals and the order of the appearance of genes from the Hfr strain is
determined in the recipient cells.

a. The order of gene transfer for each Hfr strain is:_________
b. What is the order of genes on the circular bacterial chromosome? For each Hfr strain, give the location and direction of the F factor in the chromosome

The function of the liver in humans is to maintain the [glucose] circulating in the blood stream at reasonably constant levels. This is so organs like the brain that use primarily glucose as their carbon source to produce energy via ATP have a steady supply of glucose. It also ensures that the levels of glucose in the blood stream do not get too high. Using the plots from problem 6, discuss why it makes sense that glucokinase in liver would behave differently than the hexokinase in other cells.

Introduction : Scientists who study earth's layers are called geologists. Since they cannot see inside the earth, they use geological clues to help them. These clues are gathered from activities such as volcanoes and earthquakes. From these clues , geologists make inferences about what the inside of Earth actually looks like.
Question: Name the main layers of the Earth from the inside to the surface.
