The answer is d) proteins
Explanation:
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
Researchers found that the brain's response time begins to decline at age 24. The descent is a slow, but nonetheless, steady one.
The answer is (B. Medium) because it has to travel through the ear drum evenly without busting it. Hope this helped :)
The answer is first to last with the labels going in and out of order to get an explanation
Answer:
A) The aim of the experiment is to test the plant for photosynthesis.
B) Sodium hydrogen carbonate is known to increase the amount of carbon dioxide supply to the plants. Hence, it the availability of sodium hydrogen carbonate ensures that carbon dioxide is not the limiting factor for the experiment.
C) Submerged water plants are used because using these plants makes it easier to measure the rate of photosynthesis. Water and carbon dioxide become readily available to the plant which are the reactants for photosynthesis.
