Answer:
C. Promoter; Operator
Explanation:
Related genes in bacteria are often found in a cluster on the chromosome, where they are transcribed from one RNA polymerase binding site(promoter) as a single unit while other regulatory proteins are binding repressors attached to DNA pieces known as operators. When they are bound to operator, a repressor reduces transcription.
Genes in cases like this encode proteins, having various roles which include fuel metabolism, maintenance of cell structure, and
also defense against viruses in its process. A great number of these proteins are been used while others are needed only under certain decrees. Therefore, it is said that cells don't express all the genes in their genome always.
Answer:
I'm pretty sure it's the mouse
Explanation:
Because it is eating the insects but also gets eaten by the snake.
D. weathered remains of other rocks
Explanation:
The raw material from which sedimentary rocks are formed are from the weathered remain of other rocks.
Sedimentary rocks are rocks that are derived from the deposition of rock fragments and precipitations in basins.
- Most sedimentary rocks are clastics. They are products of rock fragments that have been weathered.
- Some are chemical rocks that forms from the precipitation of minerals from solutions.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments.
- The sediments are used to produce sedimentary rocks when carried away and deposited in basins.

Answer:
I agree with Joelle.
Explanation:
Just out of common sense, not all cells are the same.
-Sienctists have studied and evaluated that cells in different matter have different make-ups. For instance, plant have cell walls and a cell membrane while animals (incluing humans) only have a cell membrane. Plants have a chloroplast, used to make their own food using the process photosythesis, While animals don't, an consume other living things.
-I don't know if you have to fill it out or anything, but if you were to fill it out, You'd put a check under each cell part for each thing.
