Answer:
24 million years
Explanation:
A: GCACTAAGCATCGATTT
B: GCACCAGGCACTGGTTC
There are 6 base pair changes between species A and species B. Since we know the rate of change is 1 base pair every 4 million years, we know 6x 4 million is likely how long ago the species diverged. 6x 4 million = 24 million years
Answer:To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics.
Explanation:
Aerobic bacteria cause an infection on the surface of the skin, and anaerobic bacteria cause an infection in a heart muscle.
An aerobic bacteria can survive and grow in a oxygenated environment. A perfect environment is the skin because it's in contact with a lot of oxygen.On the other hand, an anaerobic bacteria cannot grow in the presence of oxygen. So for them to cause an infection, they need to be in a place without this gas, just like the heart which a deep tissue.
