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

When do your lungs work the hardest
Alisiya [41]
When exercising is when the lungs work the hardest because you're using a lot of muscles and are running around and are using force in your body so the lung works really hard to make sure the body gets enough air while working out.

Explain how an oil spill devastates marine life when animals get covered by the toxic sludge.
vekshin1
Oil sticks to birds preventing them from flying. Whales and dolphins and other creatures that use blow holes can get oil into their respiratory system, making it difficult to breathe. Animals can also ingest the oil. This can be fatal and/or deadly in the short or long term.
