1)How long did it take for the third of population to double?How long did it take for the population to double a third time? 2) 51 years
___________ A third time? It took 75 years for the population to double a second time and it took 51 years to double a third time. It will reach 8 billion at about 2024. 4.
Answer:
An increase in the amount of CO2 well increase the rate of photosynthesis, Carbon dioxide concentration will directly affect the rate of photosynthesis as it is used in the photosynthesis reaction.Increased amount of CO2 will increase the rate of photosynthesis to a certain limit, after which a further increase in its amount will no longer increase the rate any further. This is when the other factors necessary for photosynthesis, such as light, become "limiting reactants"; that is, those other factors also need to increase to bring about a further increase in the rate.
six molecules of water plus six molecules of carbon dioxide produce one molecule of sugar plus six molecules of oxygen
An increase in the amount of water leads to the increase in the amount of photosynthesis
The amount of water available to the plant will affect the rate of photosynthesis. If the plant does not have enough water, the plant's stomata will shut and the plant will be deprived of CO², and thus lower photosynthesis rate.
An increase in the amount of light well increase the amount of photosynthesis, if the light intensity increases the rate of the reaction will increase at a proportional rate until a certain level is reached, the rate of increases will then go down.
Other factors affecting the rate of photosynthesis :
1. Temperature
2. The availability of nutrients
Explanation:
i think that it is a generator
Answer:
The function of the pleura is to allow optimal expansion and contraction of the lungs during breathing. The pleural fluid acts as a lubricant, allowing the parietal and visceral pleura to glide over each other friction free. This fluid is produced by the pleural layers themselves.
Answer:
Binding of <u>ACh (acetylcholine) </u> to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Explanation:
It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.
Hence , the answer is <u>ACh (acetylcholine) .</u>
