Answer:

1) The main difference between Fats and Oils is that, fats are usually derived from animals, whereas oils are usually derived from plants.

Fats and oils are very important for every human body. It is mainly essential for daily dietary plan. Fats and oils are totally different from each other. In simple terms, fats are animal fats whereas oils are vegetable oils. The other difference is fats tend to be solids at room temperature; on the other hand, oils tend to be liquid at room temperature. Remember, on the daily basis the two terms can be used interchangeably because both, fats and oils contain 9 calories per grams.

2) Phospholipids are similar to triglycerides, but they do vary slightly in form and function. While triglycerides have glycerol and three fatty acids, phospholipids have glycerol, two fatty acids and a phosphate. Phosphates are molecules with charges and have oxygen and phosphorus. ... Fat cells do not store phospholipids.

3) Thoracic cavity, also called chest cavity, the second largest hollow space of the body. It is enclosed by the ribs, the vertebral column, and the sternum, or breastbone, and is separated from the abdominal cavity (the body’s largest hollow space) by a muscular and membranous partition, the diaphragm. It contains the lungs, the middle and lower airways—the tracheobronchial tree—the heart, the vessels transporting blood between the heart and the lungs, the great arteries bringing blood from the heart out into general circulation, and the major veins into which the blood is collected for transport back to the heart. The heart is covered by a fibrous membrane sac called the pericardium that blends with the trunks of the vessels running to and from the heart. The thoracic cavity also contains the esophagus, the channel through which food is passed from the throat to the stomach.

4) An organelle (think of it as a cell's internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

5) Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. Many organs working together to accomplish a common purpose is called an organ system.

6) Absorption: The process of absorbing food in the form of nutrients into the blood stream of the body. Assimilation: The process of nutrients being absorbed by each cell of the body in the form of energy. Egestion: Secretion of waste, unwanted and excess substances from the body after food the as been digestion

Rama09 [41]
<h2>Urea </h2>

Explanation:

Urea is a small nitrogenous compound which is the main end product of protein catabolism in mammals

  • Urea is a nitrogen-containing substance normally cleared from the blood by the kidney into the urine
  • It is made predominantly in the liver from ammonia and bicarbonate and is one of the main components of urine
  • The rate of synthesis varies from 300 to 600 mmol/day depending on the protein intake
  • All of this urea eventually finds its way into the urine
  • Because urea makes up a large part of the obligatory solute excretion, its osmotic pressure requires significant volumes of water to carry the urea
  • Urea passively crosses biological membranes, but its permeability is low because of its low solubility in the lipid bilayer
  • Some cells speed up this process through urea transporters, which move urea by facilitated diffusion
  • Urea is passively reabsorbed in the proximal tubule, but its route of transport is not clear
  • Urea transporters have not yet been identified for the proximal tubule
