The right and left ventricles are responsible for pumping blood while the right and left atria are responsible for receiving blood. These are the four main chambers of the heart that are responsible for transporting oxygenated blood within the body.
Answer:
Invasive species in time destory biodiversity of an ecosystems
Explanation:
So lets go over what each answer is:
Invasive species are species that invade a ecosystem, and can harm other species and take over resources.
Populatiuons are what make up an ecosystem. There are many populations in a single ecosystem.
Biotic factors are the living things found in the world.
Abiotic factors are the opposite, being the nonliving things found in the world.
Looking at these, which would eventually destroy the biodiversity(variation of species) of an ecosystem?
This would be invasive species, for it is the only answer that harms it's ecosystem.
And this is correct, for invasive species often times can cause extiction of species, or even whole ecosystems.
For example of an invasive species, if a tree-consuming and widly reporudcing insect that lives in plains, invades a pine forest, it will eventually kill off all the trees in the area.
This wont only kill off the pine trees, but harms and could potentiallu kill the species that depend on the pine trees for survival.
Answer: invasive speices.

Answer:
To write a hypothesis, you can create an "if-then" statement that indicates directionality, or you may also use the null/alternative hypothesis.
Examples:
If-then: If you get at least 6 hours of sleep, you will do better on tests than if you get less sleep.
Null: The number of pets in a household is unrelated to the number of people living in it.
Alternative: The chemicals will affect the plants.
