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."

28. What specific adaptation has the sub-type of CAM plants derived to reduce the amount of water lost in dry environments?
zhannawk [14.2K]

Answer: a. Stomata open at Night

Explanation:

As a tactic to minimize photorespiration in warm regions, many water-storing plants such as cacti and pineapples modified its method of carbon fixation. This process is called Crassulacean Acid Metabolism (CAM), following the plant family Crassulaceae, in which it was first identified. In these plants, the stomata (singular, stoma), specialized openings in the leaves of all plants through which CO2 enters and water vapor is lost, open during the night and close during the day. This model of stomatal opening and closing is the opposite of that in most plants.

Does carrying capacity influence the survival of a population?
aivan3 [116]
'<span>Does carrying capacity influence the survival of a population?'

The answer you're looking for is something along the lines of Yes, because a carrying capacity that is too small will be easy prey, while a carrying capacity that is too large will consume it's needed resources too quickly.

Hope this helped!</span>
