Define gas exchange and distinguish between a respiratory medium and a respiratory surface

Biology
1 answer:
algol134 years ago
5 0

Answer: Hope this helps

GAS EXCHANGE: the intake of Oxygen and the expulsion of Carbon dioxide. In the capillaries of the alveoli, oxygen travels due to the concentration gradient into those capillaries. Carbon dioxide is then expelled from those capillaries.  

RESPIRATORY MEDIUM: is air for animals and water for fish. It is basically the substance through with living animals receive their oxygen.  

RESPIRATORY SURFACE: is where the gaseous exchange takes place. The oxygen and carbon dioxide move across the respiratory surface entirely by diffusion.

Vadim26 [7]

After absorption, long-chain fatty acids and monoglycerides inside intestinal cells are reformed into triglycerides.

<h3>What are triglycerides?</h3>

Triglycerides are lipids in the body composed of three fatty acids and one glycerol molecule.

Triglycerides are a fundamental lipid in the blood and they serve as a source of high-level energy.

In conclusion, after absorption, long-chain fatty acids and monoglycerides inside intestinal cells are reformed into triglycerides.

How do organic compounds differ from inorganic compounds?
Dennis_Churaev [7]

All the organic compound differs from inorganic compound by carbon composition.

Answer: Option A

<u>Explanation:</u>

An organic compound is a compound which is composed of one carbon particles binded with different components. Most generally, these carbon molecules are clung to hydrogen, oxygen and nitrogen particles. On the other hand,  an inorganic compound is not basically made out of carbon molecules.

There can be either carbon atoms present or missing. Thus it can be inferred that the presence and absence of carbon determines whether a compound is inorganic or organic.

In mitosis, when do the sister chromatids align with centrosomes in the cells?
USPshnik [31]

Answer:

The answer is probably B. Metaphase

Explanation:

In mitosis, the sister chromatids align in the "center" of the cell as the centrosomes are at the poles of the cell. They do this, moving on to the next phase Anaphase - where they will eventually split. Interphase isn't part of mitosis - it describes the period in which the cell is just growing and copying DNA.  If you textbook says it is, then thats ok, sometimes its included as part of it (even though technically its not).

What are the properties of clay, and what are the properties &amp; structure of loam soils.
pantera1 [17]

Answer:These properties include: cation exchange capabilities, plastic behaviour when wet, catalytic abilities, swelling behaviour, and low permeability. (clay)

f sand (particle size > 63 micrometres (0.0025 in)), silt (particle size > 2 micrometres (7.9×10−5 in)), and a smaller amount of clay (particle size < 2 micrometres (7.9×10−5 in)). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. (Soil)
