Answer: False
Explanation:
Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.
It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.
It depends on the state of activity. It transports more oxygen to the tissue that require it the most.
Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .
Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.
Answer:
With decrease in pH of ocean water, the survival rate of corals, algae, and fish in coral reef reduces.
Explanation:
Coral reefs find difficulty in living in acidic ocean water. It is so because the coral’s shell that is made up of calcium carbonate is unable to sustain in acidic environment.
Not only this the skeleton of snails, clams, algae , fish etc is also made up of calcium carbonate. Increased acidity leads to death of these species.
Thus, the lower is the pH of ocean water, the higher is its acidity and hence the lower is the probability of survival of corals, algae, and fish in the coral reef
The mitochondria. An organelle with a very curious history....
Answer:
Metabolism is the sum total of all the chemical reactions that occur inside the cells.
a) Catabolic pathway: release energy
b) Anabolic pathway: consume energy
c) Anabolic pathway: build up larger molecule
d) Catabolic pathway: break down molecules
e) Uphill: Anabolic
f) Photosynthesis: Anabolic
g) Cellular respiration: catabolic
Explanation:
All the chemical reactions that occur inside the cells are collectively termed as metabolism. There are two types of metabolic reactions. The reactions that break down the large molecules into the smaller ones and release the energy stored in the chemical bonds of the larger molecules are the catabolic reactions. Cellular respiration breaks down glucose into CO2 and H2O to release the energy stored in it. It is an example of the catabolic pathway.
The reactions that synthesize the larger molecules from the simpler substances are anabolic reactions. These are the endothermic reactions and therefore, are also called "uphill" reactions. An example includes photosynthesis that builds glucose from simpler substances like CO2 and H2O.
