Answer:
b, a, d, c, e
Explanation:
The lac operon is called lactose operon is a cluster of genes with a promoter. The bacteria uses lactose as the source of energy by the proteins coded by genes. This is present in prokaryotes.
The regulatory gene codes for repressor protein. The repressor binds to lactose and prevent its binding to operator. In the absence of lactose repressor gets activated and binds with operator. Thus, RNA polymerase is prevented from binding the promotor. The transcription of genes inhibited. Thus correct order is b, a, d, c, e.
Answer:
Waste is broken down, phosphate is released
Explanation:
The short cycle consists of the following:
- Waste from living things is recycled by decomposers
- Decomposers break down wastes and dead tissues
- Decomposers release the phosphates into the soil

they conduct a literature review before formulating any hypothesis. carrying out a literature review involves utilizing research databases to look for research materials that cover or are related to a certain topic of interest. the scope of the study and subject matter will influence the selection of research materials. information in these material play a crucial role when scientist are formulating hypothesis.
Answer:
Ridges = crust formation
Trenches = crust destruction
Explanation:
Mid-ocean ridges are areas of rifting where two tectonic plates are diverging from one another. Magma rises up through the rifts and forms mountain ranges. The largest is located in the middle of the Atlantic. Rifting creates new crust.
Deep-ocean trenches are formed at convergent plate boundaries where the more dense plate (usually the oceanic) subducts under the less dense (usually continental). Subduction destroys old crust and is often accompanied by volcanoes. They are common along the pacific rim.
