It is a true statement. We do this with tomatato plants all the time. If you have ever looked closely at a tomatato plant you will notice tiny hairs on it, each hair can grow a new root system. So I cut it off then place it in a grow seed tray with some support and it grows a whole new plant. You do have to remove the leaves except the very top ones say 15-20 leaves should be left on the plant you want a bare stem up to that. Also works witha variety of ivy plants.
The correct answer is (A and E) The operator region where the mutation occurs and the operator does not binds to the repressor normally.The mutation can also occur in the Lacl gene which leads to an inactive lac repressor.
- The lacI gene helps in regulation of lac operon. It is also responsible for the metabolism of lactose in bacteria.
- The mutation could have occured in the operator region, where after mutation the repressor would not be able to bind to operator.
Hi there!
Composite volcanoes, shield volcanos, and cinder cone volcanos are all different types of volcanos found on the Earth's surface.
Igneous is a type of rock typically produced by volcanoes, so it is not a type of volcano.
Therefore, the correct answer is B. Igneous.
