Answer:
contour farming
Explanation:
Contour farming is the method of growing crops on sides of hills, mountains and steep slopes by planting on graduated terraces built into the slope. This method effectively reduce soil erosion and water loss and maximizes arable land area. In most of the systems the contours are low, flat ridge of earth built across the slope, with a channel for runoff water just above the ridge. In areas where soils are able to take in water and rainfall amount is relatively low, level terraces may be used to reduce soil erosion too.
The answer is b because ferns are primitive vascular plants and seeded plants are one of the characteristics of vascular plants
The correct answer is D. Flask 3 (only). This is because fish produce carbon dioxide products of cellular respiration and they do not undergo photosynthesis therefore not consuming carbon dioxide.
This is where cellular respiration is being involved.
Cellular respiration is termed as process and reaction of metabolic which takes place in organisms where biochemical energy are converted to adenosine triphosphate from nutrients where waste product is being released.
Catabolic reactions is involved in cellular respiration where large molecules are broken to small molecules so as to release energy.
Answer:
For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it. Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs. ... Your circulatory system delivers oxygen-rich blood to your bones.
