When water is evaporated heat is what?
When water is evaporated, heat is absorbed from the surroundings in order to break the bonds between water molecules. This absorbed heat causes the water molecules to gain enough energy to change from a liquid to a gaseous state.
What does food mix with in the somach and what is the semi dried liquid now caled?
The organ system that includes thegastrointestinal tract (GI tract) and its accessory organs. The digestive system processes food into molecules that can be absorbed and utilized by the cells of the body. Food is broken down, bit by bit, until the molecules are small enough to be absorbed and the waste products are eliminated.
What is the term for the chemical or mechanical breakdown of food into molecules small enough to be absorbed by cells?
digestion
The breakdown of food into molecules small enough to enter the bloodstream is primarily accomplished by the?
The breakdown of food into molecules small enough to enter the bloodstream is primarily accomplished by the process of digestion. This involves mechanical and chemical breakdown of food in the mouth, stomach, and intestines, with the help of enzymes, to break down macromolecules into smaller molecules that can be absorbed by the body.
What is the broken down product of lipids?
Lipids ARE basically fat. which are broken down by enzymes to tun into glucose aka energy fr the body above statement not fully correct thus this shall be suffice: Lipids are fats (which is correct) and they are broken down into free fatty acids by specific enzymes called Lipases. after being broken down into these small enough molecules it can then be absorbed into our blood plasma within the 'ileum' of the small intestine via the 'villi' (the finger like projectiles in which absorbs nutrients such as broken down molecules of fat further via the capillaries and arteries) However in saying so, the broken down fat molecules requires a specific absorbtion system called the 'Lymphatic system'- the fats after being initilally absorbed into the villi, it then specifically is further abosorbed by the 'Lactel' which is located in the middle of a single villi. Furthermore, in short hand, Lipids are fats, and they break down into small enough molecules of 'free fatty acids' through the process of chemical diegstion (in this particular digestion of this nutrient this occurs within the small intestine -the duodenum to be exact) by specific enzymes of lipases.
Why do food need to be digested?
The food that we eat needs to be digested, or broken down, so the particles are small enough to be able to be absorbed into our cells. The process of digestion has four parts. Ingestion, digestion (mechanical and chemical), absorption, and elimination.
Why do nutrients need to be broken down before they can be absorbed by the human body?
Nutrients need to be broken down into smaller molecules because the human body can only absorb these smaller molecules. Enzymes in the digestive system break down proteins into amino acids, fats into fatty acids and glycerol, and carbohydrates into simple sugars. This allows the nutrients to be absorbed through the wall of the small intestine and into the bloodstream for use by the body.
What is the process by which molecules at the surface of a liquid absorb enough energy to change to a gaseous state?
The process is called evaporation. Molecules at the surface of a liquid gain energy from the surroundings, typically heat, causing them to overcome the intermolecular forces holding them together. Once they have enough energy, these molecules transition to the gaseous state and escape from the liquid surface.
What is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called?
The process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state is called evaporation. This occurs when the kinetic energy of the molecules overcomes the intermolecular forces holding them in the liquid state.
How did water vapor form?
Water vapor forms when water molecules gain enough energy to break free from liquid water and become a gas. This process, known as evaporation, occurs when heat energy is absorbed by liquid water, causing the molecules to move faster and escape into the air.
What is the prosses when a gas changes to a liquid?
Evaporation occurs when the inter particular bonds are broken. Example: In water the molecules of water (particles) are held together by a type of dipole interaction called hydrogen bonding between molecules. When enough energy is added to the water these bonds are broken and the water evaporates. Evaporation can occur at any temperature but all the molecules have enough energy at the boiling point.
Why sugars can be absorbed by diffusion?
Any chemical (not just sugars) can be absorbed by diffusion if its outside concentration is higher than its inside concentration and the membrane between the outside is permeable to that chemical (either because it has pores large enough for molecules of the chemical to pass or it has a property called "semipermeability" which allows the molecules to effectively temporary "dissolve" in the membrane to pass through it).
