This probably is Yeast cells they can respire both aerobically and anaerobically. they prefer the presence of oxygen as aerobic respiration produces more energy that anaerobically and produces less waste products than anaerobic respiration.
hope that helps
I believe the answer is indeterminate embryonic cells. Determinate cleavage or the mosaic cleavage (cell division in early embryos) is in most protostomes. It results in the developmental fate of the cells being set early in the embryo development. A cell can only be indeterminate if it has a complete set of undisturbed animal/vegetal cytoarchitectural features. It is a characteristic of deuterostomes- when the original cell in a deuterostome embryo divides, the two resulting cells can be separated and each one can individually develop into a whole organism.
D. Myosin and actin do not fully detach, so the muscle cannot relax.
In framing farmers use pesticides kill crop pests. But pesticides can have unexpected and unwanted effects on other organisms too. These chemicals harm other species living around the farm. Besides, farmers often use chemical fertilizers to increase the crop productivity but excess use of fertilizers can cause water pollution. Polluted water can kill fish and other aquatic organisms. In this way farming affects biodiversity.
The correct answer is: D, a decreased number of oxygen-rich mitochondria.
