Answer:
peristalsis.
Explanation:
Food moves through your GI tract by a process called peristalsis.
The answer would be D - boom and bust cycle. In a biological framework with two predator and two prey species, hypothesis predicts two manners by which the species' populace elements can end up coupled. On the off chance that the two predators eat both prey, at that point prey populaces will waver together, blasting when predators are uncommon and smashing when predators, looked with a prey excess, blast thus. In any case, if every predator eats a different prey, and the two prey species contend, hypothesis says the prey populaces will sway out of adjust from each other, as initial one, at that point alternate, commands assets.
Answer:
The chemical element which would be the most reactive with other elements is: D. helium, #2.
A chemical property is a property of a chemical substance that is observable and measurable in the course of a chemical reaction. The chemical properties of a chemical substance include the following:
- Tarnishing.
- Heat of combustion.
- Flammability.
- Acidity.
- Chemical reactivity.
Chemical reactivity is a property that determines how readily a chemical element would bond with other chemical elements to form a new compound.
Basically, the ability of a chemical element to bond with other chemical elements is highly dependent on the number of valence electrons.
The chemical elements Neon and Argon are noble elements, and as such have a filled outermost shell and wouldn't react with other chemical elements.
Helium has a single valence electron in its outermost shell while Boron has three (3) valence electrons in its outermost shell.
In conclusion, Helium with an atomic number of two (2) would be the most reactive with other elements.

Answer: We are evolving to the environment, and the changes around us. And those that don't die
Explanation:
They put pressure on us to adapt in order to survive the environment we are in and reproduce. It is selection pressure that drives natural selection ('survival of the fittest') and it is how we evolved into the species we are today. Genetic studies have demonstrated that humans are still evolving.
