What causes oxygen to diffuse from the lungs into the capillaries?
malfutka [58]

Answer:

Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.

what is the significance of diffusion and osmosis in living organism ?give one example in support of your answer​
olasank [31]

Answer:

Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).

Examples of where diffusion is important;

In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.

Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.

Which organisms have the least amount of stored energy in an ecological pyramid
Alenkinab [10]
<h2>Answer</h2>

Tertiary Consumers get least amount of the energy.

<h2>Explanation</h2>

In an ecological pyramid less energy is available to organisms in the upper level because each organism releases some of the chemical energy as food and to the air as thermal energy .Therefore primary consumers get almost 10% of autotrophs prduced energy. The second consumers in the pyramid get 1% from primary consumer. In the case of tertiary consumers, they get only 0.1%. Hence the top consumer of a food pyramid receives the least energy.

Sunny_sXe [5.5K]

Answer: A (ATP only)

Explanation:

Both NADH and pyruvate are energy store. NADH and pyruvate can not directly be used to drive biological reaction.The metabolism of pyruvate releases energy in the form of ATP. NADH produces ATP through the electron transport chain (ETC). Adenosine Triphosphate (ATP) is referred to as the energy currency of the cell. ATP is used directly as energy to drive endergonic and exergonic biological reaction.

Answer is ATP only
