Answer:

Begin to prepare

Explanation:

When the National Weather Service issues a severe weather alert you should start preparing. Stock up on survival articles and wait for the National Weather Service to announce new information. If you need to evacuate to a safer area or shelter, you will be advised not only of the need for evacuation, but also of the availability of shelters in the city. It is important to always be aware of the National Weather Service announcements to know what to do in dangerous weather.

katen-ka-za [31]

Answer:

sympatric speciation

Explanation:

Species of fruit fly larvae in the genus Rhagoletis each feed on a particular kind of fruit. Rhagoletis pomonella feeds on the small red fruit of the hawthorn tree. In 1865, farmers in the Hudson River valley found that R. pomonella flies had begun attacking their apples and then spread to apple orchards in adjacent areas of Massachusetts and Connecticut. These now separate varieties of flies, the apple and haw flies, usually don't interbreed with each other because their periods of mating coincide with the different ripening times of apples and hawthorn fruit. Each variety is becoming specialized to feed and reproduce in its own particular microhabitat and may be transitioning to separate species.If the apple and haw flies become distinct enough to be separate species, their evolution is an example of sympatric speciation

The lactose (lac) operon in E. coli is an example of a repressed gene when lactose is not available in a cell. In 3-5 sentences
irakobra [83]

Answer:

Please find the detailed explanation of this statement below

Explanation:

Firstly, a repressed gene is a gene whose expression has been inhibited or repressed. The lac operon in E.coli bacteria is a regulatory unit containing structural genes, a single promoter and operator regions. The promoter is the region where the transcription enzyme (RNA polymerase) binds to in order to transcribe the genes in the lac operon. The structural genes in the lac operon can only be expressed in the presence of lactose sugar.

However, in the absence of lactose, LAC REPRESSOR, which is a transcription factor (protein), prevents the binding of RNA polymerase to the PROMOTER region by binding to the OPERATOR region of the lac operon. This inhibits the expression of the lactose genes in the operon.

Note that, the structural genes in the lac operon (lacZ, lacY, lacA) code for proteins that help break down lactose sugar for energy in the E.coli bacteria. Therefore, a bacteria cell with a repressed lac operon will be unable to degrade lactose sugar.

¿Qué caracteriza el magma de los volcanes?
Sati [7]

Answer:

El magma es una roca líquida y semilíquida extremadamente caliente ubicada debajo de la superficie de la Tierra.

Como la roca sólida, el magma es una mezcla de minerales.
