Answer:
Platelets would release signals to stimulate the production of more platelets
Explanation:
Positive feedback mechanism is one of the two types of feedback mechanisms (other being negative feedback mechanism) in which the products of a process stimulates more of that product to be synthesized or produced. In other words, the result of a reaction increases the secretion of more results.
In this case where the injured tissue of a cut initially releases chemical signals into the bloodstream. These chemicals signal platelets to be attracted to the injured area. However, if this is a positive feedback mechanism as explained above, Platelets would release signals to stimulate the production of more platelets.
B - the lion eats the grass—it cannot be A. because grass gives off o2 not co2
Answer:
1. Green beetles and red beetles exist in the environment.
2. Birds that eat the beetles move into the environment.
3. Red beetles are eaten by birds, but green beetles aren’t eaten.
4. Green beetles pass on their color trait to future offspring.
5. The entire population of beetles eventually becomes green in color.
Explanation:
According to the theory of natural selection, only those species survives which fits closely with their environment. According to the conditions given, there are two genetic variations of the same species based on the color, i.e. green and red. Initially, both red and green are living together in a grassland (green in color). Then, birds enter the same environment because they have food there (beetles). Now, green beetles will take a competitive advantage because of the color and avoid getting eaten by the birds. However, red beetles would be prominent and eaten fast. The green beetles will pass on their genetic variation causing the color to be green in their future offspring and a time will come when there will be on green beetles in the area.
Carbon capture and sequestration
While it's not a power generation technology, carbon capture and sequestration—technologies that allow for the scrubbing of carbon from power plants for storage in underground reservoirs—may finally be coming of age after years of trial and error.
Technology pilot demonstrations at coal-based power plants in places like Australia and the U.S. have sparked new interest in the technology.
The hope is, it could become an enabler for other technologies, such as biomass or algae-based biofuels that produce carbon emissions. That's because organic fuels pull carbon from the atmosphere before converting it to fuel.
I believe you are referring to the Disney cartoon "The Aristocats."
At one moment during the film, one of the cats called Marie falls off the truck and into a river. However, she is saved by one of the Aristocats called Thomas O'Malley, a feral cat who falls in love with the Duchess and acts as a fatherly figure to her kittens.
