Heat, light, sound and fire may have been involved when the Bunsen burner was lit with the spark from the Van de Graaff generator. Bunsen burner is a common device in the lab.
<h3>What is a Bunsen burner?</h3>
Bunsen burner is a laboratory device (gas burner) that generates a single open gas flame.
The gas most commonly used in Bunsen burner is generally natural gas, i.e., methane gas.
This device (Bunsen burner) can be used to generate a heat source during a lab experiment.

i believe the answer is b radioactive nucleotide
Answer:
Let's consider that the allele 'B' is for Black hair colour and it is dominant. Let's consider that the allele for red hair colour is b.
Let's consider the allele for lacking horns or polles is 'P' and it is dominant. The allele for having horns is 'p' and it is recessive.
When two heterozygous black, lacking horns (BbPp) are crossed, the results will have the probability of 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned organisms.
Answer:
1) Break down of the nuclear membrane allowing mitotic spindles to connect to kinetochores:A. Metaphase
2)APC degrades securin which allows separase to become active which degrades the cohesin rings: E. Anaphase
3) Dephosphorylation of nuclear pore and lamins: F.Telophase
4) cleavage of plasma membrane by actin and myosin contractile ring:D.Cytokinesis
5) copying of the genome:C. Interphase
6) formation of the metaphase plate:B. Prometaphase
