Answer:
For most of us, between 60 and 100 beats per minute (bpm) is normal.
Explanation:
The rate can be affected by factors like stress, anxiety, hormones, medication, and how physically active you are.
I hope this helps!
brainliest is appreciated... :}
Two haploid cells is the outcome
Because they are 2 different Allotropes of Carbon
Allotropes are different forms of an element existing in the same physical state. Diamond and Graphite are both be up if carbon atoms and are both in the solid state.
Like I said Allotropes exist in different forms.
Diamond has a tetrahedral structure and it's colourless and transparent. This makes it very hard and dense. it's the hardest substance known. It has no valence electrons so it's a bad conductor of electricity.
While Graphite has an hexagonal structure and is held together by weak intermolecular forces. this makes it soft and slippery. it is a very good solid lubricant. It has valence electrons so it is a good conductor of electricity.
So how Well do u know the difference know?
Fairly sure that would be secondary succession.
