What is the substance inside the chromosomes that directs the cells activities?
The substance inside chromosomes that directs a cell's activities is called DNA (deoxyribonucleic acid). DNA contains the genetic instructions needed for the development, functioning, and reproduction of living organisms. It serves as a blueprint for the synthesis of proteins and is essential for the regulation of cellular processes.
What substance lowers the energy needed to start a chemical reaction?
A substance that lowers the energy needed to start a chemical reaction is a catalyst.
What is the name of the energy needed to change a substance from a liquid to a gas?
The energy needed to change a substance from a liquid to a gas is called the enthalpy (or heat) of vaporization.
What chemical substance in needed for photosynthesis?
Sugar and oxygen
What part of the cell is responsible for lipid synthesis?
The endoplasmic reticulum (ER) is responsible for lipid synthesis in the cell. Specifically, the smooth endoplasmic reticulum (SER) is the region where lipid synthesis occurs, involving enzymes and processes needed for lipid production.
What vitamin is needed for synthesis of prothrombin?
Vitamin K
What is the correct color tube for thrombin test?
The correct color tube for a thrombin test is typically a light blue tube. This tube contains sodium citrate as an anticoagulant, which is needed for coagulation studies.
What substance is needed for hemoglobin synthesis?
Hemoglobin is the protein that, along with water, makes up a red blood cell. Hemoglobin is made from two substances, heme and globin. In order for hemoglobin synthesis to take place, two chains of globin must connect to one another. Without these chains, hemoglobin synthesis cannot happen.
Which vitamin is essential for blood clotting?
Calcium is a very important vitamin involved in blood clotting because calcium ions are used in the thrombin. The thrombin is a product of prothrombin, calcium ions and thromboplastin. When thrombin is added with fibrinogen (which is inactive) it creates fibrin, which forms the clot.
What are ribosomes required for?
ribosomes are needed for protein synthesis.
What are the substance needed for photosynthesis what substance are produced during photosynthesis and?
CO2 and water is needed. Oxygen and glucose are produced

What affects purity of a substance?
The purity of a substance can be affected by factors such as the presence of impurities, the methods used for synthesis or extraction, storage conditions, and handling procedures. Impurities can lower the purity of a substance, and repeated purification steps or analytical techniques may be needed to increase purity.
Why does the iron present in the blood does not rust?
A substance or complex of substances called prothrombin activator is formed in response to rupture of vessels or damage to the blood itself. The detailed mechanism by which prothrombin activator is formed are still incompletely understood, however, both involves a series of plasma proteins, especially beta- globulins which along with other blood clotting factors like factor IV (calcium)enter into clotting process. 2.Prothrombin activator catalyzes the conversion of prothrombin into thrombin in the presence of calcium. 3.The thrombin acts as an enzyme to convert fibrinogen into fibrin threads that enmesh platelets, blood cells and plasma to form a hard blood clot. Citrates and oxalates which are commonly used as anticoagulants are effective because they remove calcium from the blood by formation of insoluble citrate or oxalate salts of calcium. If calcium is added in excess the clotting power of blood is restored. In formation of oxy-hemoglobin, oxygen does not combine with two positive valences of the ferrous iron in the hemoglobin molecule. Instead, it binds loosely with one of the six "coordination" valences of the iron atom. This is an extremely loose bond so that combination is reversible. Furthermore, the oxygen does not become ionic oxygen but is carried as molecular oxygen to the tissue where it is released into the tissue fluids in the form of dissolved molecular oxygen rather than ionic oxygen. This explains why blood does not rust despite having the all necessary substrates for the formation of the rust
What substance is needed for steel to rust?
Oxygen
