The carbon dioxide carried in the blood is actually combined with water and carried in the red blood cells in the form of carbonic acid, which has a dissociation constant:
H₂CO₃ ↔ H⁺ + CO₃⁻
When the pH of the blood decereases, the concentration of H⁺ ions in the blood becomes high. This causes the equilibrium to shift backwards, as per Le Chatelier's principle. The H⁺ ions are converted back to carbonic acid and the pH is increased. The opposite occurs when the pH is too high.
Answer:
c
Explanation:
active transport does move nutrients to areas with concentraition they do this and its called active transport because the body is activly moving it to a different part
Phytoplankton refers to the microscopic marine species that thrive at the bottom of the food chain. They obtain their energy from carbon dioxide via photosynthesis, like plants and thus are very essential in carbon cycling.
Phytoplankton forms the base of almost every ocean food web. Thus, it can be stated that they make the majority of other ocean life possible. They are the source of food for zooplankton and small fishes, as well as for larger animals like jellyfish and whales.
Thus, if the population of phytoplankton gets declined, it will indirectly affect other species in the aquatic ecosystem. It can also be said that with the decrease in the population of phytoplankton, the population of other major species in the ecosystem also gets a decline.
Answer:
The correct answer is option B.
Explanation:
On seeing the question, it is clear that it is based upon the concept of semi-conservative theory for the replication of DNA. It is mentioned that when the bacteria were grown on N-15, the mass was 55 fg. Now, after two generations, the DNA would comprise N-14 and the mass of them will be 5.4 fg.
The average mass would be = 5.4 + 5.5 / 2 = 10.9 / 2 = 5.45 fg. The mass of the bacteria isolated from the culture would possibly contain both the masses. That is, the mass of DNA with N-14 only would be 5.4 fg, and the mass of DNA with both N-15 and N-14 would be the average, that is, 5.45 fg.
yes carbohydrate and fats are the main source of energy in all living things almost.
as we know plants store food in form of starch and animals in the form of glycogen both are carbohydrates. they can easily be formed and also broken down to give instant energy in the form of ATP.
Fats are another source which is used as a long term storage and used when there is a need of ATP in fast or starvation.
