Answer:

the oxygen should be concentrated in the alveoli

Explanation:

Diffusion: The movement of molecules from a region og higher concentration to a region of lower concentration.

So when the Oxygen is concentrated in the alveoli only then it can move towards the blood

Diffusion is a passive transport system which means it doesnt need energy in the form of atp molecules

if the molecules move from a region of lower concentration to a region of higher concentration it needs atp molecules which is energy and is called active transport system

If the hawks are increased in this model, the grass will increase in the food chain.

<h3>What is a Food chain?</h3>

This is defined as the sequence of transfers of matter and energy in the form of food from one organism to another.

When hawks are increased, the primary consumers will decrease which are the ones who eat the grass. This will therefore lead to an increase in the grass population.

Describe the chemistry, major food sources, and roles of phospholipids and sterols
lesya692 [45]

Phospholipids and sterols are very important for human diet.

  • Phospholipids are molecules connected to fat that include phosphorus, fatty acids, and a base that contains nitrogen.
  • They have a glycerol backbone similar to triglycerides, but instead of three fatty acids, it is joined to two fatty acids and a phosphorus group.
  • Phospholipids are crucial molecules since they make up a crucial part of cell membranes. They support the flexibility and lack of rigidity of organelle and cell membranes. 
  • As the majority of a cell's membrane, phospholipids are crucial for cells.
  • Sterols have a distinctive four-ring structure with carbon and hydrogen atoms as its main building blocks.
  • The most well-known sterol is cholesterol, which is essential for cell membrane formation and the building block of many significant chemicals in the body.
