For gradualism changes in species is slow an gradual, occurring in small period changes in the gene pool, whereas for punctuated equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non- change.
Answer: Water. The pH level is 7.
Explanation: The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic.
Answer:
Crossing over and random alignment of chromosones
Explanation:
Photosynthesis and cellular respiration basically are dependent on one another. Photosynthesis produces a product of glucose, and oxygen as a byproduct. Cellular respiration uses both glucose and oxygen to produce carbon dioxide and water which are needed for photosynthesis to occur. Humans, animals and plants depend on the cycle of cellular respiration and photosynthesis for survival.
