Answer:
        <em>P      p</em>
<em>P</em>    PP   Pp
<em>p    </em>Pp    pp
PP=Homozygous purple
Pp= heterozygous purple
pp=homozygous White
Explanation:
 I tried to type out the cross. The bold letters are the heterozygous  plants that you are crossing. and the normal letters are the offspring of the two heterozygous parents being crossed. Heterozygous means they are different alleles. Homosygous means the same alleles are present.
heterozygous= Pp
Homozygous= PP or pp

The correct answer is A - leaves that close when touched.
The Venus flytrap is a type of flowering plant that is best known for its unique adaptation to trap live insects using a trap.
The trap is made up of two hinged lobes at the end of each leaf, with hair like projections called trichomes that cause the lobes to snap shut when prey comes into contact with them. 
This type of movement is called thigmonasty which is a non directional plant response to being touched.
 
        
             
        
        
        
Answer:
The half-life of a substance is the amount of time it takes for half of that substance to decay. However, after two half-lives, half of the half remaining will decay, leaving you with one quarter of the original substance.
So, after 1 million years you will have 50% of the original substance remaining.
And, after 2 million years you will have 25% of the original substance remaining.
After 3 million years you will have 12.5% of the original substance remaining.
And after 4 million years you will have 6.25% of the original substance remaining.
