Darwin's proposed mechanism for evolution is natural selection. Natural selection allows species to respond to their surroundings through time, or to become progressively excellently-suited. Natural selection is environmentally based and involves established heritable variation within a population.
They lead to changes in species over time:
- Darwin suggested species will evolve over time, new species originate from pre-existing species, and all species share a common ancestor with each other.
- In this framework each organism has its own special set of heritable i.e genetic variations from the common ancestor that have slowly developed over very longer periods of time.
- Parroted branching activities that isolate new species from a common ancestor create a multi-level tree that connects all living organisms.
The type of solution formed is hypertonic.
<h3>What are hypertonic solutions?</h3>
Hypertonic solutions are solutions with higher dissolved solutes as compared to the sap of the cells suspended in them.
Epsom salt is made up largely of magnesium sulfate. Thus, a solution formed by dissolving Epsom salt is water will have more magnesium in it than the cells of the part of the body soaked in it.
Hence, such a solution is hypertonic.

False. The number of trees is more than the number of trees cut down.
Answer:
A child...? Sorry if I'm wrong, this one's kind of confusing me.
Explanation:
While there is no graph provided and I cannot find the graph online, I will base my answer through theory.
In theory, the most common blood type is O+, followed by A+, then B+, then AB+. Rh negative blood is deemed to be rare. While the most common blood type is O+, the same blood type is also called the "universal donor" as a type O+ blood has no antigens attached in red blood cells therefore the probability of adverse reactions (i.e. hemolytic reactions) when transfused to other blood types are close to nil. In an emergency situation, wherein there is not enough time to do proper crossmatching, blood type O+ can be used therefore supplies of blood type O+ are easily depleted.
