False. 

If ice melts, it becomes water, and when it boils it becomes evaporation, until the process is repeated and it becomes ice again. 

That is an example of a change in matter that happens to be PHYSICAL!

NOT BIOLOGY ITS PHYSICAL SCIENCE how are the allotropes of carbon similar and how are they different?
Rashid [163]

Allotropes of carbon includes substances such as graphite, diamond or buckminsterfullerene.



They’re all similar in the thing that they’re all made out of carbon only.


However, their structure is different, such as graphite has a layer structure, diamond has a tetrahedral structure, and buckminsterfullerene has a spherical structure.  



Since they have different structures, they have different physical properties too. For example, diamond is hard because all the carbon atoms in the structure is held together by strong covalent bonds, while graphite are graphene layers that are held by weak intermolecular forces which makes the layers slide over each other easily thus making graphite soft.

A pea plant with purple flowers (and unknown genotype) is crossed with a pea plant with white flowers. one-half of the offspring
Archy [21]
The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).  
 For example:  
 If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>
