Use the principles of diffusion to explain why oxygen molecules in the tissues of the lung go into the blood
Keith_Richards [23]

Answer:

Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.

Explanation:

Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.

Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.

Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.

Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.

The production and consumption of atp during photosynthesis and cellular respiration. be detailed in where atp is made, and wher
Reika [66]
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide in the process of respiration, which is then used in photosynthesis. While water is broken down to form oxygen in photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.  ATP is manufactured as a result of several processes including fermentation, respiration and photosynthesis.

Which option is a balanced equation for photosynthesis? A. CO2 + H2O &gt; C6H12O6 + O2 B. 6C6H12O6 + 6O2 &gt; 6CO2 + H2O C. C6H1
Karolina [17]

The answer is; D

A balanced equation is one that observes the law of thermodynamics on the conservation of matter and energy. Matter or energy cannot be created or destroyed but can only be transformed.

In this equation, therefore, the number of elements on the right side of the equation should match those of the left side. Of the choice equations, this is a balanced one; 6CO2 + 6H2O --> C6H12O6 + 6O2 and one that reflects the process of photosynthesis.

Bacterial conjugation
lord [1]

Answer:

Yes, these are correct.

Explanation:

  • Bacterial conjugation is the bacterial counterpart of sexual reproduction. Also known as horizontal gene transfer, it involves the transfer of genetic material from one F+ or Hfr bacterium to another F+ or F- bacterium.
  • The F or fertility factor is a crucial component of the bacterial plasmid and it accounts for the development of sex pili which are important for conjugation. An F+ cells contains the F-factor incorporated into its plasmid, whereas an F- cell lacks the F-factor and therefore cannot participate in conjugation.
  • Conjugation between an F+ and F- cell can result in the transfer of the F-factor to the F- bacterium.
  • An Hfr bacterium contains F-factor incorporated into its circular genome.
