Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.
- Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
- A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
- Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.

Answer:
B. Fewer pesticides are needed because of parasitoids.
Explanation:
Herbicides are chemicals utilized to manage or command unwanted vegetation. Herbicide employment happens most commonly in row-crop cultivation, where they are employed before or throughout seeding to maximize yield productivity by decreasing other vegetation. Yields have improved considerably, and, in association with tillage, herbicide use decreases erosion, fuel usage, greenhouse gas discharges, and nutrient run-off, and preserves water.
Answer:
caffeine is a stimulant of the central nervous system
Explanation:
Caffeine is a substance that acts on the central nervous system to increase the resting metabolic rate, thereby energy drinks with caffeine can increase the number of calories burned at rest. Energy drinks are generally composed of stimulants such as, for example, caffeine, taurine and glucuronolactone, in addition to substances associated with mental alertness (e.g., B vitamins, panax ginseng root extract, L-carnitine, etc). It has been shown that the overdose of caffeine may be associated with palpitations, high blood pressure, type 2 diabetes (caffeine reduces insulin sensitivity), etc. Moreover, it is also important to highlight that energy drinks generally contain high sugar levels (around 40 grams of sugar for each beverage). In consequence, well-reputed health organizations discourage the use of energy drinks in order to avoid stimulant ingredients and reduce the consumption of sugar-sweetened beverages.
Answer:
Explanation is the answer.
Explanation:
DNA and RNA are different from their structure, functions, and stabilities. DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil. Also, DNA is double-stranded and RNA is single-stranded which is why RNA can leave the nucleus and DNA can't. Another thing is that DNA is missing an oxygen.
Answer:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted.
