What is the connection between DDT and pyrethroids? They are both pesticides, but different ones. However, many mutations that protect the bugs from one of them also work on the other.
So, if they had been exposed, they'd be selected for resistence to these pesticides. But if they have not been exposed; they would be dying more often during the last decade.
The shape of snowflakes is influenced by the temperature and humidity of the atmosphere.
<span>Snowflakes form in the atmosphere when cold water droplets freeze onto dust particles. Depending on the temperature and humidity of the air where the snowflakes form, the resulting ice crystals will grow into a myriad of different shapes.</span>
Answer:
Genetic engineering has its grass roots from the recombinant technology.
Explanation:
Genetic engineering is seen to have started from a scientists activity which involved restriction enzymes and DNA ligases that were used by Paul Berg in 1972 to create the first recombinant DNA molecules. A monkey virus which is SV40 was combined with a lambda one. Following that, the results of the experiment and attempts were further investigated by other scientists and later, the first plant that underwent genetic engineering was the plant tobacco.
<span>These are the three most common types of stresses that occur at different types of plate boundaries.
Compression- convergent boundaries
Tension- divergent boundaries
Shear- transform boundaries
Therefore, Compression, or compressing stress, is the major type of stress that occurs at convergent plate boundaries.</span>
The circulatory system circulates blood around the body. The blood passes through the lungs, where it loses carbon dioxide and gains oxygen. All cells need oxygen to function and carbon dioxide is a form of waste produced in the cells. The digestive system breaks down food and absorbs.
