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.

Answer:
A gas-powered lawn mower is a complex machine because for it to function it does more than one motion. For example, it has a wheel and axle system so it can move when powered. And it has a system of simple machines and other parts that are put together to accomplish the task of cutting grass.
Explanation:
Answer:
Hematocrit is a blood test that can identify anemia, dehydration and even heart disease. Generally, if the hematocrit values are too low, it can indicate the presence of anemia. If the hematocrit value is too high, the number of red blood cells in your blood is very high.
Explanation:
Hematocrit is a blood test that measures the percentage of the volume of all blood that is made up of red blood cells. If the hematocrit value increases, it is usually a sign that the body is not oxygenating well, and it compensates for it by increasing the number of red blood cells. If the hematocrit value decreases, it indicates anemia, the red blood cells or erythrocytes are cells capable of transporting oxygen to the tissues; Therefore, when they are reduced, a deficit of oxygen supply to the cells occurs, causing various symptoms. The heart tries to bring more blood supply to the tissues with the intention of increasing its oxygenation, for this reason the heart rate increases, producing tachycardias that are perceived as palpitations.
The medium would be functionally classified as a growth medium. It is because a growth medium is a media that is being use to observe the growth of bacteria such as having to observe whether it would be inhibited or whether it will grow in the media.
