joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.
Answer:
The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other.
Explanation:
For example, the output of photosynthesis is the input of glucose production or cellular respiration. The output of glucose production is the input of photosynthesis. Photosynthesis involves the use of energy from sunlight, water, and carbon dioxide to produce glucose and oxygen. Cellular respiration uses glucose and oxygen to produce carbon dioxide and water. To emphasize this point, even more, the equation for photosynthesis is the opposite of cellular respiration.
Answer:
A considerable increase in phytoplankton populations in winter, and a greater increase in spring due to increase in light intensity.
Explanation:
Nitrogen and phosphorus are important nutrients required by phytoplankton populations. The growth of phytoplankton populations is dependent on the level of the availability of Nitrogen and Phosphorus in the presence of sunlight.
A rise in the aquatic coastal levels of nitrogen and phosphorus would result in a great increase in phytoplankton populations in spring, as stimulated by nutrient enrichment coupled with the availability of sunlight during spring. Phytoplankton populations would increase also in winter but not as high when compared to the rise in population in spring
Answer:
The classic symptoms of asthma include wheezing, coughing, tightness in your chest, and feeling short of breath. But other conditions — like allergies, chronic obstructive pulmonary disease (COPD), sleep apnea, and post nasal drip — can trigger the same problems.
