Answer:

The concentration of chemical auto inducers increases with increase in population density

Explanation:

There is something known as Quorum sensing which is a sort of cellular communication in bacteria established through chemical signals. A bacterium is enabled to observe/monitor the environment and thus produce a widespread change in the species with in a community. These sensing processes are effective only when large numbers of cells are doing sensing controlled process together. A bacteria releases auto-inducers whose concentration increases when the population density of cells increase.

"When autoinducers produced by one bacterium cross the membrane of another, they bind to receptors in the cytoplasm. This autoinducer/receptor complex is then able to bind to DNA promoters and activate the transcription of quorum sensing-controlled genes. In this way, individual bacteria within a group are able to benefit from the activity of the entire group."

Which structure is highlighted? proximal convoluted tubule descending loop of Henle distal convoluted tubule ascending loop of H

SVETLANKA909090 [29]

Answer:

distal convoluted tubule

Explanation:

This is the region of the nephron downstream the macula densa ,which extends the to convulence of the collecting duct.Due to response to mineralocoticoid aldosterone they can be categorised as Distal Convoluted 1 and Distal convoluted 2. This steroid hormones is responsible for homeostatic control of hyperkalemia.

The DCT cells are simple cuboidal epithelium.The stained or pointed part of the image represented this possess this shape,they are therefore portion of DCT. Besides the stained cells are located above the glomerulus ()in the cortex as indicated,therefore they can not be the proximal which must be below the glomerulus, based on the shape ascending and descending loop of Henle (despite located in the cortex too).

The functions of the DCT is in the absorption and secretions of ions(majorly ca+,Na+ and chloride ions.By secreting hydrogen and reabsorbing HC03 ions ,the pH of the urine is maintained.

Which is a difference between bacteria and viruses that showed that bacteria are living organisms and viruses are not?

Zigmanuir [339]

The difference between bacteria and viruses that show bacteria are living and not viruses is that viruses, unlike bacteria, lack what is considered a living organism. For Example, viruses cannot reproduce without the help of a host, and don't use the normal way of cell-division for replication. Unlike bacteria, which can reproduce without the aid of a host.

So basically viruses don't have what it need to be a living organism, like reproducing without and host and aren't in the norm for cell-division for replication.
