Answer:

The outer layer of a cell that acts as a gatekeeper to a cell is the Cell Membrane or Plasma Membrane.

The cell membrane made up of mostly phospholipids and proteins and is known as selectively permeable membrane as it allows the entry of some selective molecules into it.

The plasma membrane is the layer present between  the cell and its external  environment. As the gatekeeper takes care of entry, cell membrane also regulates the molecules that enters and exits the cell from external environment.

Cells membrane helps in maintaining appropriate amount of molecules to function inside them.

Hence, the correct option is Cell Membrane.

Why is hamburger, of all meat, particularly vulnerable to bacterial contamination such as that caused by E. coli?
My name is Ann [436]
When cattle are slaughtered and processed, E. coli bacteria in their intestines can get on the meat. Ground beef combines meat from many different animals, increasing the risk of contamination. E. coli bacteria on a cow's udder or on milking equipment can get into raw milk or runoff from cattle farms can contaminate fields where fresh produce is grown. Certain vegetables, such as spinach and lettuce, are particularly vulnerable to this type of contamination.

Which of the following statements best describes bacteria?
zubka84 [21]

Answer:

d. Genes that play a role in the same metabolic pathway are organized into an operon.

Explanation:

In prokaryotic organisms like bacteria, polycistronic mRNAs exist which means that each gene does not have a separate promoter of its own. In fact many genes are under the control of a single promoter. These genes being a part of same metabolic pathway are organized into an operon. For example, lac operon and tryptophan operon. In lac operon, three genes named as β-galactosidase, permease and transacetylase are expressed under a single promoter which is known as lac promoter.

In contrast to this, in eukaryotes the mRNAs are monocistronic i.e. only a single gene is controlled under a single promoter.
